Description

  The present invention relates to a radiation image capturing apparatus, a radiation image capturing system, and a capturing control method for a radiation image capturing apparatus that detect radiation and acquire radiation image information.

  In the medical field, a radiographic imaging apparatus that irradiates a subject with radiation, detects the radiation transmitted from the subject with a radiation detector, and converts it into radiation image information is widely used. In recent years, still image shooting and moving image shooting are sometimes performed by a single radiographic image capturing apparatus (see, for example, Patent Document 1).

  The radiographic image capturing device (radiation detection device) disclosed in Patent Document 1 performs still image capturing in a normal state, and performs moving image capturing by connecting an additional function module. In addition, the radiographic imaging device of Patent Document 1 is configured as a portable electronic cassette, a radiation detector (sensor panel) and its control unit (basic configuration) are accommodated inside the casing, and a handle is provided outside the casing. Provided. When carrying the electronic cassette, the operator can easily carry the electronic cassette by gripping the handle.

  By the way, in the portable electronic cassette, when the radiographic image is taken (when the radiographic image information is acquired), the installation portion of the handle becomes an extra space. For this reason, Patent Document 2 discloses a technique for using a handle in a radiographic imaging apparatus (X-ray detector). That is, the handle of the radiographic imaging apparatus disclosed in Patent Document 2 includes an interface for transmitting / receiving data to / from an external apparatus, and an interface for supplying power to a radiation detector or the like. When this handle is attached (coupled) to the housing, data transmission / reception and power supply can be performed.

  Now, when taking a still image with a radiographic imaging device, a doctor, an engineer, or a nurse holds the handle attached to the housing and performs the positioning operation of the device (housing), or the subject holds the handle. Thus, the positioning and holding of the apparatus may be performed. For this reason, the handleability of the apparatus is better when the handle is attached to the housing.

  However, when performing moving image shooting, the position of the radiographic image shooting device is fixed, and shooting is often performed for a relatively long time, and a handle protruding from the housing is an obstacle. For example, because the handle protrudes from the housing, it may require an unreasonable posture of the subject depending on the shooting part of the subject. It becomes.

  The present invention has been made in view of the above circumstances, and when performing video shooting, it is possible to set the posture of the subject and the arrangement of the apparatus more freely by detaching the handle from the housing. Thus, it is an object of the present invention to provide a radiographic image capturing apparatus, a radiographic image capturing system, and an imaging control method for the radiographic image capturing apparatus that can reduce the burden on the subject even when capturing images for a relatively long time.

  In order to achieve the above-described object, the present invention provides a housing that houses a radiation detector that detects radiation and converts it into radiation image information, and is detachably attached to the housing, when the housing is carried. A radiographic image capturing apparatus including a grippable handle, wherein the radiological detector is controlled to selectively perform still image capturing for acquiring still image information and moving image capturing for acquiring moving image information. A control unit that determines whether the handle is attached to or detached from the housing, enables the photographing of the still image when the handle is attached, and removes the handle. The moving image shooting can be performed.

  According to the above, the control unit determines the attachment / detachment state of the handle with respect to the housing, and enables video shooting when the handle is detached, so that still image shooting and movie shooting are performed based on the attachment / detachment state of the handle. Can be easily switched. Further, when performing moving image shooting, since the handle is detached from the housing, the posture of the subject and the arrangement of the radiographic imaging device can be set more freely. As a result, it is possible to reduce the need for an unreasonable posture of the subject, and to prevent the position of the photographing location from being displaced due to the movement of the subject and to reduce the burden on the subject, etc.

  The housing is provided with a communication connector that can be connected to a communication cable for transmitting a signal between the radiographic imaging device and the external device, and the handle is attached to the housing. The communication connector may be covered when the cover is removed, and the communication connector may be exposed when the cover is detached from the housing.

  Thus, when the handle is attached to the housing, the handle covers the communication connector, so that liquid or dust can be prevented from entering the communication connector when the housing is carried. Then, by exposing the communication connector in a state where the handle is detached, the communication cable can be connected to the communication connector, and the moving image information acquired by moving image shooting can be easily sent to the external device.

  In this case, the communication cable may be a high-speed communication cable capable of transmitting the moving image information acquired by the control unit to the external device at a high speed.

  As described above, when a high-speed communication cable capable of high-speed transmission to an external device is used, for example, moving image information whose data amount is increased by being shot at a frame rate such as 30 frames / second (fps) is transmitted. However, it can be smoothly transmitted to the external device.

  The communication cable may be connected to a power line communication modem that performs power line communication.

  In this way, when the communication cable is connected to the power line communication modem that performs power line communication, for example, when taking a radiographic image outside a medical institution, the radiographic image information is transmitted via an electric wire wired indoors. Transmission (power line communication) can be performed. For this reason, the radiographic image information image | photographed indoors can be simply sent with respect to the round-trip car and visiting vehicle which are parked outdoors.

  Further, the housing is provided with a power connector that can be connected to a power cable for supplying power to the radiographic imaging apparatus from an external power source, and the handle is attached to the housing. The power connector may be covered so that the power connector is exposed when the power connector is detached from the housing.

  Thereby, since the handle covers the power connector in a state where the handle is attached, it is possible to prevent liquid and dust from entering the power connector when the casing is carried. Then, with the handle detached, the power connector can be exposed to connect the power cable to the power connector to supply power to the radiation detector and the control unit. Even when shooting a large moving image, it is possible to continue shooting without worrying about the amount of electricity stored in the battery.

  Here, it is preferable that the handle has a cable housing portion that houses the communication cable or the power cable.

  This eliminates the need to carry a communication cable separately from the radiographic imaging device, thereby reducing forgetting of the communication cable.

  Further, the housing has a heat radiating port capable of releasing heat generated from the radiation detector or the control unit at least during the moving image shooting, and the heat dissipation is performed when the handle is attached to the housing. It is preferable to cover the mouth and expose the heat radiating port when the mouth is detached from the housing.

  In this way, by releasing heat generated from the radiation detector or the control unit through the heat radiating port, the inside of the housing can be cooled, and moving image information can be stably acquired even when moving image shooting is performed for a long time. be able to.

  In this case, the handle may include a locking portion that is locked to the heat radiating port, and the locking portion is locked to the heat radiating port so that the handle is attached to the housing.

  As a result, the handle can be securely locked to the housing. Further, since the heat radiation port is used for locking, it is not necessary to separately form a hole or the like for locking the handle in the housing, and the manufacturing process of the apparatus can be facilitated.

  In order to achieve the above object, the present invention includes a radiation source that irradiates a subject with radiation having a predetermined irradiation energy amount, and a radiation detector that detects radiation transmitted from the subject and converts the radiation into radiation image information. A radiographic imaging system comprising: a housing for housing; and a radiographic imaging apparatus including a handle that is detachably attached to the casing and can be gripped when the casing is carried, wherein the radiographic imaging apparatus includes: A control unit that selectively performs still image shooting for acquiring still image information and moving image shooting for acquiring moving image information by controlling the radiation detector; The attachment / detachment state of the handle is detected, the still image shooting can be performed when the handle is attached, the moving image shooting can be performed when the handle is detached, and the release is performed. Ray source, with the switching of the moving image capturing and the still image shooting by the control unit, and wherein the switching the irradiation energy amount of the radiation.

  The present invention also includes a housing that houses a radiation detector that detects radiation and converts it into radiation image information, and a handle that is detachably attached to the housing and can be gripped when the housing is carried. A radiographic imaging device imaging control method comprising: a control unit that selectively performs still image shooting for acquiring still image information and moving image shooting for acquiring moving image information by controlling the radiation detector A detection step in which the control unit detects the attachment / detachment state of the handle with respect to the housing, and the still image shooting can be performed when the handle is attached, and the handle is detached. And a switching step for enabling the moving image shooting.

  According to the present invention, it is possible to set the posture of the subject and the arrangement of the apparatus more freely by detaching the handle from the casing, and this makes it possible to reduce the burden on the subject even when shooting a video for a relatively long time. Can be reduced.

One surface (irradiation surface 16) of the housing 12 is made of a material that can transmit the radiation X (see FIG. 5), and a guide line 16a serving as a reference for an imaging region and an imaging position is formed on the irradiation surface 16. Is done. In addition, surfaces other than the irradiation surface 16 of the housing | casing 12 may be comprised with the same material as this irradiation surface 16, or may be comprised with another material (for example, material which shields a radiation).

  Further, on the side surface 12a of the housing 12 to which the handle 14 is mounted, a USB (Universal Serial Bus) terminal 18 as an interface capable of transmitting / receiving information to / from an external device (including a console 78 described later), A card slot 22 for loading the memory card 20 is provided.

  On the other hand, the handle 14 is attached to the central portion of the side surface 12a of the housing 12 so that the weight balance when carrying the radiographic imaging device 10 can be maintained. The handle 14 has a rectangular base end connecting portion 24 that is in contact with the housing 12 in a state of being attached to the housing 12 and an arc shape that protrudes outward from the base end connecting portion 24 and has a predetermined thickness. The unit 26 is configured. The base end connection portion 24 is provided with a main configuration of a lock mechanism 28 (see FIG. 3) that firmly connects and fixes the housing 12 and the handle 14. This prevents the handle 14 from inadvertently dropping from the housing 12.

  As shown in FIG. 2, when the radiographic imaging apparatus 10 is transported, an operator (a doctor, a technician, a nurse, or the like) holds the grip portion 26 with the handle 14 attached to the housing 12. Can be carried easily. The operator grasps the handle 14 and transports the radiographic imaging apparatus 10 to outside the medical institution (for example, disaster site, accident site, health check-up or home nursing site, etc.), so that the radiographic image is captured at the site of the transport destination. For example, radiographic imaging of an accident site victim or disaster site victim using the imaging apparatus 10, radiographic imaging of a person who undergoes a health checkup (examiner), home care that requires home care It is possible to take a radiographic image of a person.

  FIG. 3 is a cross-sectional view taken along line III-III in FIG. 1 and schematically shows an internal configuration of the radiographic image capturing apparatus 10. A radiation detection panel 30 (radiation detector) that detects radiation X and a control unit 32 (still image capturing control unit 34, which controls driving of the radiation detection panel 30) are provided in the housing 12 of the radiographic image capturing apparatus 10. A moving image shooting control unit 36, a shooting switching control unit 38), a battery 40 that supplies power to the radiation detection panel 30 and the control unit 32, and a cooling fan 42 that cools the radiation detection panel 30 and the control unit 32 during shooting. Provided.

  For example, the radiation detection panel 30 temporarily converts the radiation X transmitted through the subject 44 into visible light by a scintillator, and converts the converted visible light into a solid detection element (hereinafter, pixel 46) made of a substance such as amorphous silicon (a-Si). Indirect conversion type that converts to an electric signal is applied. In this case, the radiation detection panel 30 includes an ISS (Irradiation Side Sampling) method (surface reading method) in which a solid detection element and a scintillator are arranged in this order along the radiation X irradiation direction, and a scintillator along the radiation X irradiation direction. Any of PSS (Penetration Side Sampling) method (back surface reading method) arranged in the order of the solid state detection elements can be adopted. In addition to the indirect conversion type described above, the radiation detection panel 30 employs a direct conversion type in which the dose of radiation X is directly converted into an electrical signal by a solid detection element made of a substance such as amorphous selenium (a-Se). You can also

  FIG. 4 is a circuit diagram schematically showing the configuration of the radiation detection panel 30 of FIG. As shown in FIG. 4, the radiation detection panel 30 includes an array of TFTs 48 in which photoelectric conversion layers in which pixels 46 made of a substance such as a-Si that converts visible light into electrical signals are formed are arranged in a matrix. It has a structure arranged on the top. In this case, in each pixel 46, the charge generated by converting visible light into an electrical signal (analog signal) is accumulated, and the charge can be read out as an image signal by sequentially turning on the TFT 48 for each row. .

  A gate line 50 extending parallel to the row direction and a signal line 52 extending parallel to the column direction are connected to the TFT 48 connected to each pixel 46. Each gate line 50 is connected to a line scan driver 54, and each signal line 52 is connected to a multiplexer 56. Control signals Von and Voff for controlling on / off of the TFTs 48 arranged in the row direction are supplied from the line scan driving unit 54 to the gate line 50. In this case, the line scan driving unit 54 includes a plurality of switches SW1 for switching the gate lines 50 and an address decoder 58 for outputting a selection signal for selecting one of the switches SW1. The address decoder 58 is supplied with an address signal from the still image shooting control unit 34 (or the moving image shooting control unit 36).

  In addition, the charge held in each pixel 46 flows out to the signal line 52 via the TFTs 48 arranged in the column direction, and is amplified by the amplifier 60 connected downstream. A multiplexer 56 is connected to the amplifier 60 via a sample and hold circuit 62. The multiplexer 56 includes a plurality of switches SW2 that switches the signal line 52 and an address decoder 64 that outputs a selection signal for selecting one of the switches SW2. The address decoder 64 is supplied with an address signal from the still image shooting control unit 34 (or the moving image shooting control unit 36). An A / D converter 66 is connected to the multiplexer 56, and radiation image information (still image information or moving image information) converted into a digital signal by the A / D converter 66 is used for the still image capturing control unit 34 or the moving image capturing control. Supplied to the unit 36.

  The TFT 48 functioning as a switching element may be realized in combination with another imaging element such as a CMOS (Complementary Metal-Oxide Semiconductor) image sensor. Further, it can be replaced with a CCD (Charge-Coupled Device) image sensor that transfers charges while shifting the charges by a shift pulse corresponding to the gate signal referred to in the TFT 48.

  As shown in FIG. 3, one radiation detection panel 30 described above is disposed inside the housing 12 of the radiographic imaging apparatus 10. The control unit 32 supplies an address signal to the radiation detection panel 30 to capture a radiation image. The control unit 32 selectively switches between the still image shooting control unit 34 and the moving image shooting control unit 36 before shooting, thereby performing still image shooting for acquiring still image information and moving image shooting for acquiring moving image information. To do. Note that the number of radiation detection panels 30 of the radiation image capturing apparatus 10 is not limited to one. For example, two or more radiation detection panels 30 are disposed, and still image capturing and moving image capturing are performed. It may be properly used for.

  The still image capturing control unit 34 acquires the still image information of the subject 44 by controlling the driving of the radiation detection panel 30 (that is, performing still image capturing). The still image information is, for example, one frame of radiation image information generated (converted) by detecting the radiation X output from the radiation source 83 for a predetermined time based on one imaging operation. In general, radiation X having an irradiation energy amount larger than that of moving image shooting is output from the radiation source 83 and converted into still image information. For this reason, the still image information has high resolution and clear image quality, and is used by doctors, technicians, and the like to read the state of the subject 44 (such as a medical condition).

  The USB terminal 18 and the card slot 22 are attached to the still image shooting control unit 34 so that signals can be transmitted. The front end connection side of the USB terminal 18 and the card slot 22 is fitted into the side wall 13 constituting the side surface 12 a of the housing 12 and is exposed to the outside of the housing 12.

  On the other hand, the moving image capturing control unit 36 acquires the moving image information of the subject 44 by controlling the driving of the radiation detection panel 30 (that is, performing moving image capturing). With the moving image information, for example, radiation X is repeatedly output from the radiation source 83 at a predetermined pulse interval (frame rate) based on one imaging operation, and the radiation X is detected by the radiation detection panel 30 at each pulse interval. It is converted into a plurality of radiation image information (frames). Alternatively, the moving image information may be information obtained by detecting the radiation X continuously irradiated from the radiation source 83 with a certain irradiation energy amount at each predetermined detection timing and converting the radiation X into a plurality of pieces of radiation image information. Therefore, the moving image information is configured such that a plurality of frames are continuous. In general, radiation X having an irradiation energy amount smaller than that in still image shooting is output from the radiation source 83 and converted into moving image information. For this reason, the moving image information is processed at high speed by the moving image capturing control unit 36 although the resolution is lower than that of the still image information. This moving image information is used, for example, for interpretation of a catheter inserted into the subject 44.

  The moving image shooting control unit 36 includes a communication connector 68 that transmits moving image information to an external device (for example, the console 78). The tip connection side of the communication connector 68 is fitted into the side wall 13 constituting the side surface 12 a of the housing 12. In this case, the communication connector 68 is disposed at a substantially central portion of the side surface 12 a of the housing 12, and is covered with the handle 14 when the handle 14 is attached to the housing 12.

  In addition, the shooting switching control unit 38 performs control to switch the operation of the still image shooting control unit 34 and the moving image shooting control unit 36. A handle detection sensor 70 that detects the attachment / detachment state of the handle 14 is connected to the photographing switching control unit 38. The photographing switching control unit 38 performs switching control based on the attachment / detachment state of the handle 14. The specific operation of the photographing switching control unit 38 will be described later.

  Further, the battery 40 includes a radiation detection panel 30 disposed in the housing 12, a control unit 32 (a still image shooting control unit 34, a moving image shooting control unit 36, a shooting switching control unit 38), a cooling fan 42, and a handle detection. Electric power is supplied to the sensor 70 and the like.

  The cooling fan 42 is connected to a heat radiation port 72 formed on the side surface of the housing 12, and guides outside air to a location where heat is generated during imaging (at the time of acquisition of radiation image information) by drive control of the control unit 32. As a result, the temperature inside the housing 12 can be lowered as a whole, and photographing can be performed stably. In addition, the cooling fan 42 can prevent dust from adhering to the radiation detection panel 30 and the control unit 32 by including a filter capable of adsorbing dust and the like mixed in outside air.

  A pair of heat radiation ports 72 are provided on the side surface, and have a function of sucking outside air into the housing 12 and exhausting hot air inside the housing 12 to the outside. Further, the pair of heat radiation ports 72 of this embodiment constitute a part of the lock mechanism 28 for attaching the handle 14 to the housing 12.

  On the other hand, the handle 14 has a main structure of the lock mechanism 28 in the proximal end connection portion 24 and a cable storage portion 75 for storing the high-speed communication cable 74 in the grip portion 26. The lock mechanism 28 is preferably configured to firmly lock the housing 12 and the handle 14 so that the operator can easily carry the radiographic imaging apparatus 10 by gripping the handle 14.

  For example, as shown in FIG. 3, the lock mechanism 28 according to the first embodiment has a pair of opposing hook portions 28 a and hooks the hook portions 28 a on the opening edge of the heat radiation port 72 of the housing 12. Thus, the handle 14 can be firmly locked. Further, the lock mechanism 28 includes a lock release button 28 b on one side surface of the proximal end connection portion 24. The operator can release the lock of the hook portion 28a by pressing the lock release button 28b against the internal spring 28c, thereby easily removing the handle 14 from the housing 12. Of course, the lock mechanism 28 for connecting the handle 14 and the housing 12 is not limited to the above configuration, and various configurations can be adopted. For example, the hook portion 28a may be provided in the housing 12, and a lock port (not shown) that can be locked by the hook portion 28a may be provided in the handle 14. Further, a lock mechanism 28 using a key, a password or the like may be employed.

  The cable storage portion 75 uses the internal space of the grip portion 26 of the handle 14 and stores the high-speed communication cable 74 in this embodiment. This eliminates the need to carry the high-speed communication cable 74 separately from the radiation image capturing apparatus 10, thereby reducing forgetting the high-speed communication cable 74 and the like. The cable storage unit 75 may be provided in the housing 12.

  Next, the radiographic image capturing system 11 constructed when radiographic image capturing (still image capturing) is performed using the radiographic image capturing apparatus 10 according to the first embodiment will be described.

  As the radiation irradiation device 76, for example, when a radiographic image is taken in a medical institution, a device installed at the shooting location is used. When taking a radiographic image outside a medical institution such as a disaster site, an accident site, home medical care, etc., it is carried with the radiographic image capturing apparatus 10 and a predetermined setting is made at the site. In this case, the radiographic image capturing apparatus 10 can also have a configuration in which the radiation irradiating apparatus 76 is integrally provided (for example, see Japanese Patent Application Laid-Open No. 2011-172904).

The radiation irradiation device 76 includes an input / output unit 80, an exposure switch 81, a radiation source control unit 82, and a radiation source 83.

  The input / output unit 80 is wired to the console 78 using a USB cable or the like, and transmits and receives data between the radiation irradiation device 76 and the console 78. Note that transmission / reception of data between the radiation irradiation device 76 and the console 78 is not limited to wired communication, but wireless communication (for example, UWB (Ultra Wide Band), WiFi 802.11.Wireless Fidelity such as IEEE 802.11.a / g / n). ) Or communication using millimeter waves).

  The exposure switch 81 is turned on / off by an operator or the like when taking a radiographic image, and switches the power supply from the external power source to the radiation source controller 82, the radiation source 83, and the like. The radiation source control unit 82 is activated based on an ON signal of the exposure switch 81 and controls driving of the radiation source 83 according to a predetermined control condition (for example, an imaging condition transmitted from the console 78). The radiation source 83 outputs the radiation X based on the control of the radiation source control unit 82.

  On the other hand, as described above, the radiation image capturing apparatus 10 includes the radiation detection panel 30, the control unit 32 (the still image capturing control unit 34, the moving image capturing control unit 36, the capturing switching control unit 38), the battery 40, and the cooling fan 42. Prepare. In addition, a USB cable 84 is connected to the USB terminal 18 of the radiation image capturing apparatus 10 so that data can be transmitted to and received from the console 78. Furthermore, the radiographic imaging device 10 includes a radiation source position detection unit 86 that detects a distance (distance between imaging) with the radiation irradiation device 76.

  The radiation source position detection unit 86 includes a distance sensor (not shown), for example, and detects the distance between the radiographic image capturing apparatus 10 and the radiation irradiation apparatus 76. The detection distance detected by the distance sensor is sent to the still image capturing control unit 34 or the moving image capturing control unit 36.

  The still image shooting control unit 34 includes an address signal generation unit 34a, an image memory 34b, an SID determination unit 34c, and an image processing unit 34d. The address signal generator 34a supplies an address signal corresponding to still image shooting to the address decoder 58 of the line scan driver 54 and the address decoder 64 of the multiplexer 56. The image memory 34b stores still image information detected by the radiation detection panel 30.

  The SID determination unit 34c determines whether or not the detection distance detected by the radiation source position detection unit 86 matches a preset distance (SID). That is, the SID determination unit 34 c determines whether or not the irradiation energy amount of the radiation X irradiated from the radiation irradiation device 76 is normally incident on the radiation image capturing device 10 when performing still image capturing. it can. When the detected distance does not match the SID, information indicating that the distance between the radiographic imaging device 10 and the radiation irradiation device 76 does not match is transmitted and displayed on the display unit 90 of the console 78.

  In addition, the image processing unit 34d performs predetermined image processing on the still image information acquired by the radiation detection panel 30, and stores the still image information in the image memory 34b.

  A USB cable 84 is connected to the USB terminal 18, and various data are transmitted and received between the radiation image capturing apparatus 10 and the console 78. In this case, the USB cable 84 also transmits the still image information detected by the radiation image capturing apparatus 10 to the console 78. On the other hand, the memory card 20 is inserted into the card slot 22, and still image information is stored in the memory card 20 as necessary.

  The console 78 has a function of controlling the radiation image capturing system 11 as a whole. Schematically, a control instruction signal such as an imaging condition is sent to the radiation irradiation device 76 so that the radiation X is irradiated based on the imaging condition, and the radiation X transmitted through the subject 44 is detected by the radiographic image capturing device 10. The radiation image information sent from the radiation image capturing apparatus 10 is processed (data correction, storage, etc.) and displayed on the display unit 90.

  In this case, as the console 78, a generally known computer including an arithmetic processing unit 88, a storage unit 89, a display unit 90, and an input / output unit 91 can be applied. In addition, when taking a radiographic image outside a medical institution, if a portable computer (so-called notebook personal computer) is used, it is easy to carry.

  The arithmetic processing unit 88 and the storage unit 89 are configured to execute a predetermined program for controlling the radiographic imaging system 11. For example, the imaging conditions (tube voltage, tube current, irradiation time, frame rate, cumulative exposure) for irradiating the subject 44 with the radiation X having an appropriate irradiation energy amount are set based on the preconditions such as the imaging region and the imaging method. The imaging conditions are set as appropriate, and the imaging conditions are transmitted to the radiation irradiation device 76 based on the operation of the operator. Further, the arithmetic processing unit 88 and the storage unit 89 manage information (name, sex, ID number, etc.) of the subject 44 and information (usage state, ID number, etc.) of the radiographic image capturing apparatus 10. Further, the arithmetic processing unit 88 and the storage unit 89 perform predetermined image processing on the radiographic image information acquired by the radiographic imaging device 10 and store the radiographic image information.

  The display unit 90 is configured by, for example, a liquid crystal panel, and displays the radiation image information stored in the storage unit 89 based on the control of the arithmetic processing unit 88. The input / output unit 91 includes a plurality of wired connection terminals (for example, a USB terminal 91a), and transmits and receives data to and from the radiation irradiation device 76 and the radiation image capturing device 10.

  The radiographic image capturing system 11 configured as described above enables still image capturing by setting the handle 14 to the housing 12. As a method of positioning the radiographic imaging device 10 at a predetermined position (position corresponding to the imaging region of the subject 44) in still image shooting, a dedicated loading device (standing position / stand-by position / retrofit table or retrofit, dedicated frame) : Not shown) may be set in the apparatus, and when there is no loading apparatus (for example, when photographing outside a medical institution), as shown in FIG. The radiographic imaging device 10 is disposed between a lying bed (or a floor or the like) and the subject 44. In this case, as shown in FIG. 6B, the operator may adjust the position (positioning) of the apparatus by holding the handle 14 and sliding the radiographic image capturing apparatus 10 from the lateral direction of the subject 44. Further, when taking a still image by irradiating the radiation X from the back side of the subject 44, the subject 44 holds the handle 14 (or the housing 12) as shown in FIG. 10 can also be positioned at a desired position.

  As described above, in still image shooting, the radiographic imaging apparatus 10 can be positioned relatively easily by operating the handle 14 on which the operator or the subject 44 is mounted on the housing 12. Then, the radiation X based on the imaging conditions is irradiated from the radiation irradiation device 76 disposed above the subject 44, and the radiation X transmitted through the imaging region of the subject 44 is detected by the radiographic imaging device 10 located below. The still image capturing control unit 34 performs drive control of the radiation detection panel 30 to acquire still image information, and transmits the acquired still image information to the console 78. The console 78 displays this still image information on the display unit 90.

  In still image shooting, since shooting is performed with the handle 14 attached to the housing 12, there is a possibility that the subject 44 may be requested to be in an unreasonable posture, but still image shooting can be performed in a short time. For this reason, it does not become a big burden for the to-be-photographed object 44. FIG.

  In addition, when switching from still image shooting to moving image shooting, an operation (detachment operation) for removing the handle 14 from the housing 12 is performed. The radiographic image capturing apparatus 10 according to the first embodiment can automatically switch from still image capturing to moving image capturing by detaching the handle 14. FIG. 7 is an explanatory view showing the detaching operation of the handle 14, and FIG. 8 is an explanatory view showing a state where a communication cable is connected to the housing 12.

  As shown in FIGS. 3 and 7, when removing the handle 14 from the housing 12, the hook portion 28 a that locks the handle 14 to the housing 12 is unlocked by pressing the lock release button 28 b. Do. Therefore, even when the radiographic imaging device 10 is inserted between the subject 44 and the bed (see FIG. 6B), the operator can easily remove it by pressing the lock release button 28b. Thereby, the radiographic imaging device 10 exposes the communication connector 68 and the heat radiation port 72 provided on the side surface of the housing 12.

  After the handle 14 is detached, the high-speed communication cable 74 is taken out from the cable housing portion 75 of the handle 14 and one end of the high-speed communication cable 74 is connected to the communication connector 68 exposed on the housing 12 (see FIG. 8). ). The other end of the high-speed communication cable is connected to the console 78.

  The high-speed communication cable 74 can transmit data from the radiographic image capturing apparatus 10 to the console 78 at high speed, and can smoothly transmit even moving image information whose data amount is increased by capturing at a high frame rate to the console 78. Can do.

  FIG. 9 is a block diagram illustrating an example of the radiographic image capturing system 11 when performing moving image capturing. In moving image shooting, the shooting switching control unit 38 controls the radiation detection panel 30 to be switched from the still image shooting control unit 34 to the moving image shooting control unit 36. The shooting switching control unit 38 detects the attachment / detachment state of the handle 14 by the handle detection sensor 70, and detects (determines) the removal of the handle 14, whereby the still image shooting control unit 34 moves to the moving image shooting control unit 36. Switch.

  The radiographic image capturing system 11 transmits this switching information to the radiation irradiating device 76 when the photographing switching control unit 38 switches between still image capturing and moving image capturing (that is, when the handle 14 is attached / detached). Then, the imaging conditions (setting of still image shooting and moving image shooting) of the radiation irradiation device 76 are switched. This switching information may be transmitted from the radiation image capturing apparatus 10 to the radiation irradiating apparatus 76 via the console 78, or a transceiver (not shown) is provided in the radiation image capturing apparatus 10 and the radiation irradiating apparatus 76. You may transmit directly from the radiographic imaging apparatus 10 to the radiation irradiation apparatus 76 (refer the dotted line of FIG. 5, FIG. 9).

  As shown in FIG. 3, the handle detection sensor 70 is disposed at a position close to the heat radiation port 72 and detects the presence or absence of the hook portion 28 a of the handle 14. The shooting switching control unit 38 operates the still image shooting control unit 34 when the handle detection sensor 70 detects the attachment of the handle 14, and when the detachment of the handle 14 is detected from the handle detection sensor 70, the moving image shooting control unit 36. To work. Note that the detection of the handle 14 is not limited to the handle detection sensor 70, and various means can be applied.

  As shown in FIG. 9, the moving image shooting control unit 36 includes an address signal generation unit 36a, an image memory 36b, an SID determination unit 36c, and a high-speed image processing unit 36d. The address signal generator 36a supplies an address signal corresponding to moving image shooting to the address decoder 58 of the line scan driving unit 54 and the address decoder 64 of the multiplexer 56 based on the frame rate of moving image shooting. Here, the moving image shooting control unit 36 (address signal generation unit 36a) may perform binning control for collecting a plurality of pixels 46 (for example, 2 × 2 pixels) into one pixel. Thus, even if the binning control is performed and the image quality of the moving image information is lower than that of the still image information, for example, it is possible to obtain a sufficient image quality for interpretation of a catheter or the like.

  The image memory 36b continuously stores the moving image information detected by the radiation detection panel 30 for each frame. The SID determination unit 36 c has the same function as the SID determination unit 34 c of the still image capturing control unit 34, and determines the distance between images of the radiographic image capturing apparatus 10 and the radiation irradiation apparatus 76. The high-speed image processing unit 36d performs predetermined image processing on the moving image information acquired by the radiation detection panel 30, and stores the moving image information in the image memory 36b.

  The moving image shooting control unit 36 is connected to the communication connector 68, and transmits the moving image information stored in the image memory 36 b to the console 78 via the high-speed communication cable 74 connected to the communication connector 68. To do.

  As the high-speed communication cable 74, for example, a short-distance communication cable that transmits radiation image information in parallel is applied. Thereby, even moving image information in which the amount of data transmission per unit time increases can be transmitted at high speed. Further, as the high-speed communication cable 74, an optical cable or an LVDS (Low Voltage Differential Signaling) cable may be applied.

  Of course, a normal communication cable such as a LAN cable may be used. In this case, for example, the transmission mode (protocol) is changed by the moving image capturing control unit 36 so that moving image information can be transmitted at high speed. May be. That is, when still image information is transmitted, a virtual circuit is constructed between the radiographic image capturing apparatus 10 and the console 78 in order to reliably transmit high-quality still image information, and still image information ( Data communication is performed in a TCP (Transmission Control Protocol) transmission mode in which retransmission of packet data) is performed. On the other hand, when moving image information is transmitted, data communication is performed in a UDP (User Datagram Protocol) transmission mode in which moving image information is simply transmitted without constructing a virtual circuit as non-connectionless transmission. Thus, moving image information can be smoothly displayed on the display unit 90 by transmitting moving image information to the console 78 by UDP.

  When the radiographic imaging device 10 is set in a dedicated loading device, the communication connector 68 may be connected to a connector provided in the loading device.

  The console 78 has a communication connector 91b to which a high-speed communication cable 74 can be connected. The moving image information transmitted from the radiation image capturing apparatus 10 via the high-speed communication cable 74 is image-processed by the arithmetic processing unit 88. And stored in the storage unit 89 and displayed on the display unit 90.

  The radiographic image capturing apparatus 10 and the radiographic image capturing system 11 according to the first embodiment are basically configured as described above. Next, operations thereof will be described. FIG. 10 is a flowchart showing the operation of the radiation image capturing system 11 according to the first embodiment.

  For example, when radiographic imaging is performed outside the medical institution by the radiographic imaging system 11 according to the first embodiment, the radiographic imaging apparatus 10 and the radiation irradiation apparatus 76 are arranged at predetermined positions as preparations before imaging. These devices and the console 78 are connected by wire. That is, the USB terminal 18 of the radiation image capturing apparatus 10 and the USB terminal 91a of the console 78 are connected by the USB cable 84, and the input / output unit 80 of the radiation irradiation apparatus 76 and the input / output unit 91 of the console 78 are connected by a dedicated cable ( Or a USB cable). Furthermore, the radiographic imaging system 11 is driven by starting the radiographic imaging apparatus 10, the radiation irradiation apparatus 76, and the console 78, respectively.

  After activation of the radiographic imaging system 11, the attachment / detachment state of the handle 14 is detected by the handle detection sensor 70 in the radiographic imaging apparatus 10 (step S1: detection step). The detection result of the attachment / detachment state of the handle 14 is sent to the photographing switching control unit 38, and the photographing switching control unit 38 determines whether the still image photographing or the moving image photographing is performed based on the attaching / detaching state (step S2).

  In step S <b> 2, when the radiation image capturing system 11 detects the attachment of the handle 14, it prepares to perform still image capturing (step S <b> 3: switching step). In this still image shooting preparation preparation, a still image shooting setting signal (switching information) is transmitted from the radiation image shooting device 10 to the console 78. When the console 78 receives the still image shooting setting signal, the arithmetic processing unit 88 sets shooting conditions for still image shooting, and outputs the shooting conditions to the radiation irradiation device 76. In the radiation irradiation device 76, the radiation source control unit 82 sets the tube voltage, the tube current, the irradiation time, and the like based on the imaging conditions. On the other hand, in the radiographic image capturing apparatus 10, the still image capturing control unit 34 and the radiation detection panel 30 are connected by the image capturing switching control unit 38 so that signals can be transmitted. Further, the distance between the radiographing apparatus 10 and the radiation irradiation apparatus 76 is detected by the SID determination unit 34c, and the inter-imaging distance is adjusted.

  When the preparation for performing the still image shooting is completed, the still image shooting is performed (step S4). In this case, the radiation irradiation device 76 irradiates the subject 44 with radiation X having an irradiation energy amount based on the imaging conditions. The radiation X that has passed through the subject 44 is detected by the radiation detection panel 30 that is driven based on the control of the still image capturing control unit 34, and is converted into still image information. The still image information is subjected to image processing by the image processing unit 34d and temporarily stored in the image memory 34b. Further, the still image information is sent from the radiographic image capturing apparatus 10 to the console 78 via the USB cable 84, subjected to predetermined image processing in the arithmetic processing unit 88, and stored in the storage unit 89. The stored still image information is displayed on the display unit 90 based on the operation of the operator.

  On the other hand, if it is determined in step S2 that the handle 14 has been detached, preparations for moving image shooting are made (step S5: switching step). In preparation for moving image shooting, a setting signal (switching information) for moving image shooting is transmitted from the radiation image shooting device 10 to the console 78. The console 78 sets shooting conditions for moving image shooting in the arithmetic processing unit 88 at the timing of receiving the moving image shooting setting signal, and outputs the shooting conditions to the radiation irradiation device 76. In the radiation irradiation device 76, the radiation source control unit 82 sets the tube voltage, the tube current, the irradiation time, the frame rate, and the like based on the imaging conditions. On the other hand, in the radiographic image capturing apparatus 10, the moving image capturing control unit 36 and the radiation detection panel 30 are connected by a capturing switching control unit 38 so that signals can be transmitted. Further, the distance between the radiographing apparatus 10 and the radiation irradiation apparatus 76 is detected by the SID determination unit 36c, and the inter-imaging distance is adjusted. Furthermore, a transmission path for moving image information is constructed by connecting the high-speed communication cable 74 to the communication connector 68 of the radiographic imaging apparatus 10 and the communication connector 68 of the console 78 by the operator.

  When preparation for the video shooting is completed, the video shooting is performed (step S6). In this case, the radiation irradiation device 76 irradiates the subject 44 with radiation X having an irradiation energy amount based on the imaging conditions in accordance with a predetermined frame rate (for example, 30 fps). The radiation X that has passed through the subject 44 is detected by the radiation detection panel 30 that is driven based on the control of the moving image capturing control unit 36, and is converted into moving image information for each frame. The moving image information is subjected to image processing in the high-speed image processing unit 36d and temporarily stored in the image memory 36b. Further, the moving image information is sent from the radiographic image capturing apparatus 10 to the console 78 via the high-speed communication cable 74, subjected to predetermined image processing in the arithmetic processing unit 88 and stored in the storage unit 89. The stored moving image information is displayed on the display unit 90 based on the operation of the operator.

  After the still image shooting or the moving image shooting is performed, it is determined whether or not the radiographic image is continuously captured (step S7). And when imaging | photography is continued, it returns to step S1 and repeats the same control. On the other hand, when the shooting is to be ended, a predetermined shooting end process is performed (step S8). At this time, when moving image shooting is being performed, the high-speed communication cable 74 is removed from the communication connector 68, and the detached handle 14 is attached to the housing 12. The handle 14 can be easily reattached by hooking the hook portion 28a of the lock mechanism 28 to the heat radiating port 72 at the time of attachment.

  As described above, radiation image information (still image information or moving image information) is acquired by the radiation image capturing system 11. The doctor diagnoses the state of the imaging region of the subject 44 by visually recognizing the still image information displayed on the display unit 90. On the other hand, by visually recognizing the moving image information displayed in real time, it is possible to recognize the operation (body movement) of the imaging region, the position of the catheter, and the like. In addition, the radiographic imaging apparatus 10 which concerns on 1st Embodiment can take a various aspect other than said structure.

  FIG. 11A is an explanatory diagram illustrating a mounting pattern of the handle 14 of the radiographic image capturing apparatus 10, and FIG. 11B is an explanatory diagram illustrating a state where a plurality of handles 14 are mounted on the radiographic image capturing apparatus 10.

  For example, the radiographic imaging apparatus 10 has a plurality of mounting positions (four in FIG. 11A) of the handle 14 provided on the side surface of the housing 12, and can be attached to or detached from any of the side surfaces of the housing 12 as shown in FIG. 11A. It may be configured to be mounted on Thereby, when the radiographic imaging device 10 is made to enter between the subject 44 and the bed, the handle 14 can be attached according to the direction of the entry, and the handleability can be improved.

  A plurality of handles 14 may be attached to the radiographic image capturing apparatus 10. For example, as shown in FIG. 11B, when a pair of handles 14 are mounted on both sides of the housing 12, the subject 44 holds the pair of handles 14 when taking a still image from the back of the subject 44. Therefore, the positioning and holding of the radiographic image capturing apparatus 10 can be made more reliable.

  FIG. 12A is a perspective view showing a radiographic image capturing apparatus 10A according to a first modification, and FIG. 12B is a perspective view showing a radiographic image capturing apparatus 10B according to a second modification. In the following description, the same reference numerals are given to the same components or the components having the same functions as those of the radiographic image capturing apparatus 10 according to the first embodiment, and detailed descriptions thereof are omitted.

  As shown in FIG. 12A, the radiographic image capturing apparatus 10A according to the first modification is the radiographic image capturing according to the first embodiment in that a power connector 92 is provided at the substantially central portion of the side surface 12a of the housing 12. Different from the device 10. The power connector 92 is connected to a power cable 93 that can supply power from an external power source (not shown). That is, in the radiographic image capturing apparatus 10A, power is supplied to the radiation detection panel 30 and the control unit 32 by an external power supply in a state where the handle 14 is detached from the housing 12 and the moving image can be captured.

  Here, in the moving image shooting by the radiographic imaging devices 10 and 10A, since the shooting is performed for a relatively long time, the power consumption becomes large, and the shooting is interrupted only by the power supply by the battery 40 in the housing 12. There is a possibility. Therefore, as with the radiographic image capturing apparatus 10A according to the first modification, imaging can be performed without worrying about the amount of power stored in the battery 40 by supplying power from the external power source during moving image capturing. In this case, if the radiographic image capturing apparatus 10A is configured to include an antenna (not shown) for wireless communication, the moving image information acquired by the radiographic image capturing apparatus 10A can be transmitted to the console 78. Alternatively, the image quality of the moving image information may be reduced to reduce the amount of data, and the data may be transmitted via the USB cable 84.

  In addition, if the power cable 93 is stored in the cable storage unit 75 provided in the handle 14 (or the housing 12), the handleability is improved. Further, the power cable 93 may be provided with an AC / DC conversion adapter (not shown) so that an AC power supply (commercial power supply) is converted into a DC power supply and supplied to the radiographic imaging apparatus 10A. Furthermore, 10 A of radiographic imaging apparatuses may charge with respect to the battery 40 accommodated simultaneously with video recording.

  As illustrated in FIG. 12B, the radiographic image capturing apparatus 10 </ b> B according to the second modified example is provided with a communication connector 68 and a power connector 92 on the side surface 12 a of the housing 12. Therefore, in the radiographic imaging apparatus 10 </ b> B, both the transmission of moving image information by the high-speed communication cable 74 and the power supply by the power cable 93 can be performed.

  FIG. 13 is a perspective view showing a radiographic imaging apparatus 10C according to a third modification, and FIG. 14 is an explanatory diagram schematically showing an example of use of the radiographic imaging apparatus 10C of FIG.

  As illustrated in FIG. 13, the radiographic imaging apparatus 10 </ b> C according to the third modification includes a connector (hereinafter referred to as a general-purpose connector 95) in which a communication cable (for example, a LAN cable) is connected to the side surface 12 a of the housing 12. Prepare. The general-purpose connector 95 is connected with a communication cable 94 of a PLC (Power Line Communication) adapter 96 (power line communication modem) that performs power line communication. Thereby, the radiographic image information acquired by the radiographic image capturing apparatus 10C can be transmitted by power line communication.

  For example, when a radiographic image is captured by the radiographic image capturing apparatus 10C outside the medical institution, as shown in FIG. 14, a visit car 97 (round-trip car) is parked outside the home and the radiographic image capturing system 11 is used. It is conceivable to bring only indoors. In this case, if the radiographic image information acquired by the radiographic imaging device 10C is to be stored in the management device 97a of the visiting car 97, it is temporarily stored in the memory card 20 (or other storage medium) or by a long communication cable. It is necessary to form a transmission path, and workability is reduced.

  Therefore, the radiographic imaging system 11 is constructed so that data is transmitted and received between the radiographic imaging apparatus 10C and the visiting vehicle 97 using power line communication. Specifically, the PCL adapter 96 to which the radiographic imaging device 10C is connected is inserted into a first outlet 98a provided indoors, and the management device 97a in the visiting car 97 is connected to a second outlet 98b provided on the outer surface side of the house. Plug in the PLC adapter 96 connected to. Thereby, the radiographic image information acquired by photographing indoors can be transmitted from the first outlet 98a to the second outlet 98b via the indoor wiring, and further, the radiographic image information is transmitted from the second outlet 98b to the management device 97a. It can be transmitted and stored in the management device 97a.

  Thus, by realizing the power line communication, for example, even in a situation where it is difficult to move the subject 44 indoors, the radiation image information acquired by capturing the radiation image can be easily sent to the visiting car 97. The radiation image information can be easily managed.

  15A to 15D are views showing handles 14a to 14d according to fourth to seventh modifications. As shown in FIGS. 15A to 15D, the shape and function of the handle 14 attached to the housing 12 can be freely set. That is, as shown to FIG. 15A, the handle 14a does not have the base end connection part 24, and the both ends of the holding part 26 from the housing | casing 12 may be mounted | worn detachably. Further, as shown in FIG. 15B, the handle 14 b may have a configuration in which a T-shaped gripping portion 26 extends from the proximal end connection portion 24. Further, as shown in FIG. 15C, the handle 14c may be swingable by the gripping portion 26 being connected to the proximal end connecting portion 24 (or the housing 12) via the rotating shaft 99. Furthermore, as illustrated in FIG. 15D, the handle 14 d is formed in a shape that is continuous with the housing 12. In this case, the still image shooting control unit 34 is provided in the handle 14d, and the moving image shooting control unit 36 is provided in the housing 12, so that the still image shooting control unit 34 is separated with the detachment of the handle 14d. The photographing control unit 36 can also be driven.

  The radiographic image capturing apparatuses 10, 10 </ b> A to 10 </ b> C do not include the moving image capturing control unit 36 in the housing 12, and the communication connector 68 exposed by detaching the handle 14 is similar to the moving image capturing control unit 36. An external control device (not shown) having a function may be connected and moving image shooting may be performed by this external control device. In this case, the imaging switching control unit 38 may connect the radiation detection panel 30 and the communication connector 68 in the housing 12 so as to transmit signals when switching from still image shooting to moving image shooting.

  As described above, according to the radiographic image capturing apparatuses 10, 10 </ b> A to 10 </ b> C (the radiographic image capturing system 11) according to the first embodiment, the imaging switching control unit 38 is attached or detached with the handles 14 and 14 a to 14 d with respect to the housing 12. Can be performed when the handles 14, 14a to 14d are detached, so that still image shooting and movie shooting can be easily switched based on the attachment / detachment state of the handles 14, 14a to 14d. Can do. Further, when performing moving image shooting, since the handles 14 and 14a to 14d are detached from the housing 12, the posture of the subject 44 and the arrangement of the radiographic imaging devices 10, 10A to 10C can be set more freely. Is possible. As a result, an excessive posture is not required for the subject 44, and the position shift of the shooting location due to the movement of the subject 44, the burden on the subject 44, and the like can be reduced when moving image shooting is performed for a long time.

  Further, when the handle 14 is attached to the housing 12, the handle 14 covers the communication connector 68, so that liquid and dust can be prevented from entering the communication connector 68 when the housing 12 is carried. it can. In the state where the handle 14 is detached, the communication connector 68 is exposed to connect the high-speed communication cable 74 to the communication connector 68 so that the moving image information obtained by moving image shooting can be easily displayed on the console 78 ( Or an image display device).

  On the other hand, in the radiographic image capturing apparatus 10A of the first modification, the handle 14 covers the power connector 92 with the handle 14 attached, so that liquid or dust is applied to the power connector 92 when the housing 12 is carried. It can be prevented from entering. In the state where the handle 14 is detached, the power supply connector 92 is exposed to connect the power supply cable 93 to the power supply connector 92 to supply power to the radiation detection panel 30 and the control unit 32. In addition, even when taking a video for a long time and taking a relatively large amount of power, the video can be taken without worrying about the remaining amount of electricity stored in the battery 40.

  Moreover, the inside of the housing 12 can be cooled by releasing heat generated from the radiation detection panel 30 or the control unit 32 (moving image capturing control unit 36) through the heat radiation port 72 formed in the side surface 12a of the housing 12. Thus, it is possible to stably acquire moving image information even when shooting a moving image for a long time. Furthermore, in the radiographic imaging devices 10, 10 </ b> A to 10 </ b> C according to the first embodiment, the hook portion 28 a of the handle 14 is locked using the heat radiating port 72, so that a hole or the like for locking the handle 14 is provided.

In the handle proximal end connection portion 24, a cable housing portion 75 for housing the power extension cable 116 is provided at the center portion, and the main portion of the lock mechanism 128 is provided at both end portions of the proximal end connection portion 24. The grip portion 26 of the handle 114 has a plug housing portion 130 at the center of a bar extending substantially parallel to the housing 12, and the power plug 120 is provided in the plug housing portion 130. In addition, an AC / DC conversion adapter 132 (AC / DC converter) is provided inside the bar of the grip portion 26 extending in a direction orthogonal to the housing 12.

  The cable storage unit 75 is provided with a winding mechanism 134 that winds the power extension cable 116. The winding mechanism 134 includes, for example, an operation button 136 provided outside the handle 114, a winding portion 138 around which the power extension cable 116 is wound, and a rotating portion 140 that rotates the winding portion 138 based on the operation of the operation button 136. It is comprised by. When the operation button 136 is not operated, by pulling out the handle 114, the winding portion 138 can rotate and the power extension cable 116 can be discharged. Thus, for example, when taking a radiographic image outside a medical institution, even when the outlet 118 is located away from the radiographic imaging device 110, the handle 114 can be extended and the power plug 120 can be inserted.

  The lock mechanism 128 includes, for example, a hook portion 128a that locks the heat radiation port 72 of the housing, a lock release button 128b that is provided on both side surfaces of the handle 114 and is connected to the proximal end of the hook portion 128a, and a lock with the hook portion 128a. An internal spring 128c that presses the release button 128b outward from the handle 114, and by pressing the lock release button 128b, the hook portion 128a is slid to release the lock.

  The power plug 120 is rotatable with respect to the plug housing part 130 (gripping part 26). That is, when the operator carries the radiation image capturing apparatus 110 while holding the grip portion 26, the handle 114 can be easily gripped by storing the power plug 120 in the plug storage portion 130. On the other hand, when power is supplied through the handle 114, the power plug 120 is rotated to project the insertion teeth 120 a made of a metal material from the handle 114, so that it can be inserted into the outlet 118.

  The AC / DC conversion adapter 132 is disposed between the power plug 120 and the take-up mechanism 134, and an AC power supplied from an outlet 118 (commercial power) can be used as a direct current that can be used by the radiation detection panel 30 and the control unit 32. Convert to power.

  On the other hand, the power extension cable 116 has one end connected to the winding mechanism 134 and the other end connected to the battery 40 provided in the housing 12 (see also FIG. 18). The side wall 13 of the housing 12 may be provided with a packing 142 for tightly holding the power extension cable 116 in order to improve dust resistance and waterproofness. The electric power supplied from the outlet 118 is temporarily stored in the battery 40, and the electric power necessary for driving the radiation detection panel 30 and the control unit 32 is supplied from the battery 40.

  The radiographic image capturing apparatus 110 according to the second embodiment is basically configured as described above, and the operation thereof will be described next. The radiographic image capturing apparatus 110 according to the second embodiment determines the attachment / detachment state of the handle 114 by the handle detection sensor 70 and the imaging switching control unit 38. When the handle 114 is attached, the still image capturing control unit 34 is driven to perform still image capturing. On the other hand, when the handle 114 is detached, the moving image shooting control unit 36 is driven to perform moving image shooting. The operation when performing still image shooting and moving image shooting is the same as that of the radiographic image capturing apparatus 10 according to the first embodiment.

  In the radiographic image capturing system 111, when still image capturing is performed, generally, only a few radiographic images of the subject 44 are captured, so that the capturing is performed in a short time. For this reason, even if power is supplied from the battery 40 to the radiation detection panel 30, the still image capturing control unit 34, and the like, the amount of power stored in the battery 40 is less likely to decrease rapidly and become insufficient. On the other hand, when moving image shooting is performed, it is normal that shooting is performed for a long time, and the number of processed moving image information is enormous, and power is rapidly consumed. Therefore, it is assumed that the power supply from the battery 40 alone causes power shortage relatively early.

  The radiographic image capturing apparatus 110 according to the second embodiment supplies power to the radiation detection panel 30 and the moving image capturing control unit 36 by effectively utilizing the handle 114 that has been detached in moving image capturing. Thereby, it is possible to avoid power shortage during moving image shooting, and it is possible to stably continue moving image shooting. Further, by temporarily storing the power supplied from the power extension cable 116 in the battery 40, for example, even if the power plug 120 is accidentally dropped from the outlet 118 and the power supply is interrupted, the video shooting is continued by the battery 40. And interruption of shooting can be avoided.

  Note that the moving image information acquired by moving image shooting is transmitted to the console 78 by performing wireless communication between the transmitter / receiver 144 of the radiographic image capturing apparatus 110 and the transmitter / receiver 146 of the console 78, as shown in FIG. can do. Of course, the image quality of the moving image information may be reduced to reduce the amount of data, and the data may be transmitted via a USB cable.

  FIG. 19A is a diagram showing a handle 114a of an eighth modification, FIG. 19B is a diagram showing a handle 114b of the ninth modification and a part of the housing 112, and FIG. 19C shows a handle 114c of the tenth modification. FIG. 19D is a view showing a handle 114d of the eleventh modification.

Also, the power plug 120 is housed and the plug 120a of the power plug 120 is inserted. The exposure mechanism is not limited. For example, as shown in the eighth modification (see FIG. 19A), the power plug 121a may be provided on the side surface of the handle 114a and disposed (stored) in the handle 114a so as to be movable forward and backward. . In this case, when the handle 114a is detached from the housing 12, the power plug 121a automatically protrudes the insertion teeth 120a, and when the handle 114a is attached to the housing 12, the insertion teeth 120a are automatically It is convenient to be stored in.

  As shown in the ninth modification (see FIG. 19B), the power plug 121b may be provided on the contact surface 148 where the handle 114b and the housing 112 come into contact. In particular, when the gripping portion 26 of the handle 114b is formed in an arc shape in a plan view, the insertion plug of the power plug 121b protrudes from a flat portion (contact surface 148) in contact with the housing 112. Can connect the outlet 118 and the power plug 121b closely.

  In this case, a plug storage portion 131 that can store the power plug 121b may be provided at a position facing the power plug 121b on the side surface 12a of the housing 112. That is, when the handle 114 is attached to the housing 12, the insertion teeth of the power plug 121 b are housed in the plug housing portion 131 of the housing 112. As a result, there is no need to provide a plug storage portion or an exposure mechanism on the handle 114b side, so that a simple structure can be achieved.

  Furthermore, as shown in the tenth modification (see FIG. 19C), the handle 114c may be provided with a plurality of power supply outlets 150 into which power plugs of other power-driven devices can be inserted. In this case, other power driving devices include a radiation irradiation device 76 and a console 78. As described above, by providing the power supply outlet 150, it is easy to connect the power supply outlet 150 of the handle 114c even when it is difficult to insert the power plug of another power drive device by connecting the handle 114c to the outlet 118. Can be plugged in.

  As shown in the eleventh modification (see FIG. 19D), a power cable 154 having a power plug 152 may extend from a handle 114d to which the power extension cable 116 is connected. In this case, the gripping portion 26 includes a cable storage portion 75 and can be configured to store the power supply cable 154. In this way, by further extending the power cable 154 from the handle 114d, the power plug 152 is sufficiently connected to the outlet 118 even when the distance from the imaging position (the position of the radiographic imaging apparatus 110) to the outlet 118 is greatly separated. Can be delivered to.

  FIG. 20A is a perspective view showing a radiographic image capturing apparatus 110A according to a twelfth modification, and FIG. 20B is a perspective view showing a radiographic image capturing apparatus 110B according to a thirteenth modification.

  As shown in FIG. 20A, the radiographic imaging apparatus 110A according to the twelfth modification protrudes from the side surfaces (thickness portions) of the handles 114, 114a to 114d like the power plugs 120, 121a, 121b of the second embodiment. The power plug 121c is configured to protrude from the plane portion of the handle 114e. That is, the power plug 121c protrudes in the orthogonal direction from the surface having the largest planar area (hereinafter referred to as the plug protrusion surface 156) among the six surfaces constituting the substantially rectangular handle 114e. Thus, the power plug 121c projects from the plug projecting surface 156 having a large planar area, so that the connection state between the power plug 121c and the outlet 118 can be strengthened. That is, when the power plug 121 is connected, the plug projecting surface 156 of the handle 114 comes into contact with a decorative plate (not shown) of the outlet 118. As a result, even if a load is applied in the rotation direction with the power plug 121c as a fulcrum due to the weight of the handle 114e and the power extension cable 116, the load can be received by the outlet 118, thereby effectively preventing the power plug 121c from coming off. can do.

  As shown in FIG. 20B, the radiographic imaging apparatus 110B according to the thirteenth modification has a high-speed communication cable 74 (see FIG. 8) on the side surface 12a of the housing 12 in addition to the insertion portion of the power extension cable 116. A connectable communication connector 68 is provided. One end of the high-speed communication cable 74 is connected to the console 78. Thereby, the radiographic imaging apparatus 110 </ b> B can perform both power supply by the power extension cable 116 and transmission of moving image information by the high-speed communication cable 74.

  The radiographic imaging apparatuses 110, 110 </ b> A, and 110 </ b> B may be provided with a communication cable 68 (not shown) on the power extension cable 116 and the communication connectors 68 on the handles 114 and 114 a to 114 e. Thus, even if the communication connectors 68 are provided on the handles 114 and 114 a to 114 e, wired communication can be performed with the console 78.

  As described above, according to the radiographic image capturing apparatuses 110, 110A, and 110B according to the second embodiment, the power plugs 120, 121a to 121c are attached to the handles 114, 114a to 114e configured to be detachable from the housing 12. And is electrically connected to the radiation detection panel 30 and the control unit 32 via the power supply extension cable 116, so that the handles 114, 114a to 114e used when carrying the radiographic imaging apparatuses 110, 110A, 110B are carried out. Can be used for power supply. For this reason, at the time of radiographic image capturing, the posture of the subject 44 and the arrangement of the radiographic image capturing apparatuses 110, 110A, 110B can be set more freely. As a result, it is less likely to require an unreasonable posture for the subject 44, and it is possible to prevent displacement of the shooting location due to the movement of the subject 44 and to reduce the burden on the subject 44, etc., when taking a video for a long time. it can.

  In addition, when the handles 114 and 114a to 114e are detached, the handles 114 and 114a are connected to the outlets 114 and 114a from the outlet 118 when performing movie shooting for a long time by performing movie shooting for acquiring movie information of a predetermined frame rate. To 114e and the power supply cable 116 can be used to supply power, so that photographing can be continued stably.

  The radiographic image capturing apparatuses 110, 110A, 110B connect the power plugs 120, 121a-121c to the outlet 118 by detaching the handles 114, 114a-114e from the casings 12, 112, when performing still image capturing. Of course, you may do. In this case, a switching switch (not shown) that switches between still image shooting and moving image shooting is provided, and when switching to moving image shooting is performed by removing the handles 114 and 114a to 114e, What is necessary is just to set it as the structure changed to image photography. Of course, the configuration for switching between still image shooting and moving image shooting may be adopted in other embodiments.

  Further, since the power extension cable 116 is pulled out from the cable housing portion 75 and extended by separating the handles 114, 114a to 114e from the housings 12, 112, the power extension cable 116 is inadvertently extended. It can be avoided. As a result, it is possible to reduce the chance of the power supply extension cable 116 interfering when the radiographic imaging devices 110, 110A, 110B are transported or when radiographic images are taken. In particular, the radiographic imaging apparatuses 110, 110 </ b> A, and 110 </ b> B have the winding mechanism 134 that winds the power extension cable 116 around the cable housing portion 75, so that the power extension cable 116 can be connected to the cable housing portion only by operating the operation button 136. 75 can be stored.

  Further, the AC / DC conversion adapter 132 that converts the AC power supplied from the outlet 118 to DC power and supplies it to the radiation detection panel 30 or the control unit 32 is provided in the handles 114, 114a to 114e, thereby allowing the casing to Since it is not necessary to provide an AC / DC converter in the 12 and 112, the housings 12 and 112 can be downsized.

[Third Embodiment]
FIG. 21A is a perspective view showing a state in which a handle 214 is attached to the housing 12 of the radiographic image capturing apparatus 210 according to the third embodiment, and FIG. 21B is a housing 12 of the radiographic image capturing apparatus 210 of FIG. 21A. FIG. 22 is a perspective view showing a state where the handle is detached from FIG. 22, and FIG. 22 is a block diagram showing a radiographic image capturing apparatus 210 according to the third embodiment.

  The radiographic image capturing apparatus 210 according to the third embodiment can transmit or receive signals between the electrically operable electric function module 216 and the control unit 32 and the console 78 (or other external device). It differs from the radiographic imaging apparatuses 10 and 110 according to the first and second embodiments in that the communication function module 218 is provided in the handle 214. In this case, the electrical function module 216 and the communication function module 218 are used when the radiographic image capturing apparatus 210 is brought into a disaster site, an accident site, etc., among the use of the radiographic image capturing apparatus 210 outside the medical institution. It is equipped with equipment required in

  As shown in FIG. 22, for example, the electric function module 216 provided in the handle 214 includes a camera 220, a projector 222, a light 224, and the like. Examples of the communication function module 218 include a USB terminal 226, an antenna 228, and the like.

  The camera 220 is a digital camera that can store a photograph of the surrounding environment as electronic data. Usually, it is desirable to take a picture of the state of the subject 44 and the state of the site at a disaster site or accident site. The camera 220 is used flexibly in such a situation. As shown in FIG. 21A, when the handle 214 is attached to the housing 12 and the radiographic image capturing apparatus 210 is carried, the camera 220 is in a stopped state and the lens 220a is protected by a protective cover. 230. As shown in FIG. 21B, when the handle 214 is detached from the housing 12, the camera 220 becomes operable. Then, the protective cover 230 is removed, and an operation button 232 provided on the handle 214 is operated, so that a photograph of the surrounding environment can be taken.

  Electronic data (photographing information) of a photograph taken by the camera 220 is transmitted to the console 78 via, for example, a USB cable (not shown) connected to the USB terminal 226. In addition, the shooting information may be projected by the projector 222 provided by operating the operation button 232. Thus, the operator can immediately confirm the photographing information photographed by the camera 220.

  The projector 222 projects the shooting information shot by the camera 220 as described above onto a surrounding wall or the like. The radiographic image information (still image information and moving image information) captured by the radiographic image capturing apparatus 210 is projected. Similarly to the camera 220, the projector 222 is in a stopped state when the handle 214 is attached to the housing 12 and the radiographic image capturing apparatus 210 is carried, and the lens 222 a is protected by the protective cover 230. Covered by As shown in FIG. 21B, when the handle 214 is detached from the housing 12, it becomes operable, the protective cover 230 is removed, and the operation button 232 provided on the handle 214 is operated, so that imaging information and radiation are obtained. Image information can be projected. 21A and 21B illustrate a state where the camera 220 and the lenses 220a and 222a of the projector 222 are separately provided, the camera 220 and the projector 222 may share the lens. The housing 12 (or the handle 214) may accommodate a tripod (support device: not shown) that can support the handle 214 in a predetermined posture. By fixing the handle 214 to the tripod, the projector 222 can stably project imaging information and radiation image information.

  The light 224 is turned on when the site is dark, for example, to assist the operator in visually recognizing the surrounding environment. In particular, when the site is dark, inconveniences such as difficulty in seeing operation buttons of various devices occur. Therefore, the use of the light 224 can eliminate such inconvenience. In this case, it is preferable to use an LED driven with low power as the light source of the light 224. The light 224 may have a function of irradiating a flash when the camera 220 is used.

  The electric function module 216 such as the camera 220, the projector 222, and the light 224 is supplied with power during operation from the battery 40 in the housing 12. This eliminates the need for a power source in the handle 214, so that the camera 220, projector 222, and light 224 can be mounted even if the handle 214 is small. Of course, a power source such as a battery may be disposed on the handle 214. Note that the electric function module 216 is not limited to the camera 220, the projector 222, the light 224, and the like, and it is also conceivable that an electric drive device used in the treatment is provided, for example.

  On the other hand, the USB terminal 226, which is the communication function module 218, is connected to a USB cable (not shown) in the same manner as the USB terminal 18 provided in the housing 12, and the radiographic imaging device 210 and the console 78 (or other external device). A function of transmitting or receiving a signal to / from the device. That is, the handle 214 can serve as a relay that extends the wired connection between the housing 12 and the console 78. For example, at disaster sites and accident sites, there are many opportunities to perform work (taking radiographic images, etc.) at a remote location with the management device mounted on the vehicle, and the length of the communication cable (including the USB cable 84) May be insufficient. The radiographic imaging apparatus 210 can extend the communication cable as a whole system by detaching the handle 214 provided with the USB terminal 226 from the housing 12, and can easily cope with the situation in the field. Thereby, the radiographic image capturing apparatus 210 can transmit the radiographic image (still image information and moving image information) acquired by capturing the radiographic image to an external apparatus (management apparatus) or the like via the USB terminal 226 and the USB cable. .

  The antenna 228 has a function of wirelessly transmitting or receiving a signal between the radiographic image capturing apparatus 210 and the console 78 (or other external apparatus). For example, as the antenna 228, an RF antenna capable of short-range wireless communication can be used. In this manner, by providing the antenna 228 on the detachable handle 214, wireless communication can be performed at a position where the antenna 228 is separated from the housing 12. For this reason, by arranging the handle 214 (antenna 228) in a place where the radio wave condition is good, the radiographic image information (still image information and moving image information) acquired by radiographic imaging can be transmitted more reliably.

  When the handle 214 is attached to the housing 12 (see FIG. 21A), the antenna 228 blocks the circuit so that signals are not transmitted to or received from the console 78, and the handle 214 It is preferable that a wireless communication circuit be connected when the device is detached from the housing 12. Thereby, it can suppress that the noise by radio | wireless communication mixes in the radiographic image image | photographed by irradiation of the radiation.

  Note that an electric field strength detector (not shown) for detecting electric field strength may be provided in the handle 214 as the electric functional module 216 for assisting the antenna 228. Thus, when the antenna 228 is used, the handle 214 can be positioned based on the electric field strength detected by the electric field strength detector. Further, the communication function module 218 provided in the handle 214 is not limited to the USB terminal 226 or the antenna 228, and other communication connectors and wireless communication mechanisms may be applied.

  The handle 214 and the housing 12 do not supply power to each other between the communication cable capable of transmitting or receiving signals between the electrical function module 216 and the communication function module 218, and the battery 40 and the handle of the housing. The power cable is connected by a shared cable 234. When the handle 214 is attached to the housing 12, the cable 234 is a cable storage portion provided on the handle 214 or the housing 12, like the radiographic imaging devices 10 and 110 according to the first and second embodiments. 75 should be stored.

  An interface 236 capable of transmitting or receiving signals between the electrical function module 216 and the communication function module 218 and the control unit 32 is provided in the housing 12. The control unit 32 uses the handle detection sensor 70 to determine the attachment / detachment state of the handle 214. When the handle 214 is mounted on the housing 12, the control unit 32 transmits signals to the electrical function module 216 and the communication function module 218 or Reception is prohibited and power supply to each module 216, 218 is stopped. On the other hand, when the handle 214 is detached from the housing 12, the transmission and reception of signals to the electrical function module 216 and the communication function module 218 are permitted, and power is supplied to each module 216 and 218 to operate. State.

  In this way, by controlling the operation of the electrical function module 216 or the communication function module 218 provided on the handle 214 based on the attachment / detachment state of the handle 214, for example, when the radiographic imaging apparatus 210 is carried, the operator carelessly Even if the operation button 232 of the handle 214 is pressed, the modules 216 and 218 can be prevented from operating. Further, by removing the handle 214 when taking a radiographic image, it is possible to reduce the chance that each module 216, 218 is affected by the radiation X, and to suppress the deterioration of the function due to the radiation X, etc. it can.

  FIG. 23A is a perspective view showing a state where an external battery 238 is connected to the radiographic image capturing apparatus 210 of FIG. 21B, and FIG. 23B is a perspective view showing a radiographic image capturing apparatus 210A according to a fourteenth modification.

  As shown in FIG. 23A, the radiographic image capturing apparatus 210 may be provided with a power connector 240 at a handle 214 and connected to an external battery 238 via a power cable 241. Thereby, power can be supplied from the external battery 238 to the radiation image capturing apparatus 210. For example, at a disaster site or an accident site, there is a possibility that power cannot be supplied from a facility outlet when there is no outlet (commercial power supply) nearby or due to a power failure or the like. For this reason, the power supply connector 240 that can be connected to the external battery 238 is provided in the handle 214, so that the power supply cable 241 is connected and power is supplied from the external battery 238 to the radiation imaging apparatus 210. As described above, when performing moving image shooting, power consumption increases due to reasons such as shooting for a long time. For this reason, moving images can be stably taken by supplying power from the external battery 238.

  In this case, the power supplied from the external battery 238 may be temporarily charged in the battery 40 in the housing 12. Further, the electric function module 216 (camera 220, projector 222, light 224, etc.) may be driven by power supplied from the external battery 238.

Moreover, it is preferable that the AC cable 316 has a sufficient length so that the power plug 316b reaches a relatively distant place. The AC cable 316 may be stored in a cable storage unit 75 provided in the housing 12 (or the handle 314).

  The radiographic imaging apparatus 310 supplies power to the radiation detection panel 30 and the control unit 32 from the outlet 320 (commercial power supply) by connecting the AC cable 316 having the power plug 316b inserted into the outlet 320 to the AC connector 318. be able to.

  As shown in FIG. 25, inside the handle 314 is an AC / DC conversion adapter 322 capable of converting AC power supplied from the AC cable 316 into DC power, and AC cable connection for detecting the connection state of the AC cable 316. A detection unit 324 is provided. The AC / DC conversion adapter 322 converts the AC power supplied from the AC cable 316 into a DC power that can be used by the radiation detection panel 30 and the control unit 32. The AC cable connection detection unit 324 detects the connection state of the AC cable 316 with respect to the AC connector 318 (handle 314). In this case, the AC cable connection detection unit 324 does not detect that the AC cable 316 is physically connected to the AC connector 318, but the power plug 316b is connected to the outlet 320 so that power can be supplied. The connection of the AC cable 316 may be detected.

  On the other hand, the imaging switching control unit 38 provided in the housing 12 is connected to the AC cable connection detection unit 324, and based on the detection result (connection state of the AC cable 316) detected by the AC cable connection detection unit 324, The driving of the still image capturing control unit 34 and the moving image capturing control unit 36 is switched. That is, the radiographic image capturing apparatus 310 can perform still image capturing when the AC cable 316 is not connected to the AC connector 318 (handle 314), and the AC cable 316 is connected to the AC connector 318 (handle 314). In addition, it is possible to perform video shooting.

  Further, the housing 12 is provided with a power supply switching unit 326 connected to the AC / DC conversion adapter 322. The power supply switching unit 326 is also connected to the AC cable connection detection unit 324. Based on the connection state of the AC cable 316, the power supplied to the radiation detection panel 30 and the control unit 32 is supplied from the battery 40 and the AC cable. 316 has a function of selectively switching between supply from an external power source (outlet 320) supplied via 316. That is, when the AC cable 316 is not connected to the AC connector 318, power is supplied from the battery 40, and when the AC cable 316 is connected to the AC connector 318 (the handle 314), power is supplied from the outlet 320. Do.

  Furthermore, when the AC cable 316 is connected, the power supply switching unit 326 uses the power supplied from the AC cable 316, the power supplied to the radiation detection panel 30 and the control unit 32, and the power to charge the battery 40. To distribute. Thereby, the power supply switching unit 326 can also charge the battery 40 with the power supplied from the AC cable 316.

  The radiographic image capturing apparatus 310 is configured as described above, and when moving image shooting is performed, power is supplied from an external power source (outlet 320), and long-time moving image shooting (the radiation detection panel 30 and the moving image is performed). Even when driving the imaging control unit 36), power can be stably supplied.

  Note that the handle 314 may be configured to be detachable from the housing 12 in the same manner as the radiographic imaging apparatuses 10, 110, and 210 according to the first to third embodiments. In this case, a power cable 328 capable of supplying DC power is disposed between the handle 314 and the housing 12. That is, the AC power supplied via the AC cable 316 is converted into a DC power by the AC / DC conversion adapter 322 and supplied to the radiation detection panel 30 and the control unit 32 via the power cable 328. As a result, the handle 314 functions as a relay for the two cables 316 and 328 in the entire system. Even if the outlet 320 is installed at a relatively far place from the radiographic imaging location outside the medical institution, the AC cable 316 can be delivered. In this case, the AC cable connection detection unit 324 may be provided on the housing 12 side and may detect the connection value of the AC cable 316 by detecting the current value of the DC power supplied to the housing 12. Good.

  FIG. 26 is an explanatory diagram schematically showing an overall configuration of a radiation image capturing system 311 according to the fifteenth modification.

  The radiographic image capturing system 311 according to the fifteenth modification is configured to perform power line communication using an AC cable 316A connected to the radiographic image capturing apparatus 310. Thereby, the radiation image information (still image information or moving image information) acquired by the radiation image capturing apparatus 310 can be transmitted by power line communication.

  Specifically, the AC cable 316A to which the radiographic imaging device 310 is connected is plugged into a first outlet 330 provided in the room, and a management device in the visiting vehicle is connected to a second outlet 332 provided on the outer surface side of the house. Plug the AC cable 316A. Thereby, the radiographic image information acquired by photographing indoors can be transmitted from the first outlet 330 to the second outlet 332 via the indoor wiring, and further, the radiographic image information is transmitted from the second outlet 332 to the management device 334. Can be transmitted and stored in the management device 334.

  As described above, by realizing the power line communication using the AC cable 316A, for example, even in a situation where it is difficult to move the subject 44 indoors, the radiation image information obtained by capturing the radiation image is obtained as the visiting vehicle 336. The radiation image information can be easily managed.

  As described above, according to the radiation imaging apparatus 310 according to the fourth embodiment, the radiation detection panel 30 is connected via the AC cable 316 by connecting the AC cable 316 capable of supplying AC power to the handle 314. In addition, power can be supplied to the control unit 32. In addition, the shooting switching control unit 38 determines whether the AC cable 316 is attached to or detached from the housing 12, and can perform still image shooting when the AC cable 316 is disconnected. The power of the battery 40 is used for shooting. On the other hand, by enabling moving image shooting when the AC cable 316 is connected, shooting can be performed without worrying about the amount of power stored in the battery 40 even for moving image shooting with a relatively long power consumption. Can continue.

  In this case, by providing the handle 314 with an AC / DC conversion adapter 322 that converts AC power supplied from the AC cable 316 into DC power, the internal space of the handle 314 can be effectively used. Moreover, since it becomes unnecessary to provide a DC converter in the housing 12, the housing can be reduced in size.

  Note that the power line connected to the radiation imaging apparatus 310 is not limited to the AC cables 316 and 316A that supply AC power, and various modes can be adopted. For example, a DC power cable (not shown) may be connected to the radiographic image capturing apparatus 310 as an electric lamp line, and direct current power may be supplied to the radiographic image capturing apparatus 310 to capture a radiographic image. In this case, since it is not necessary to provide the AC / DC conversion adapter 322 in the housing 12 or the handle 314, the apparatus can be reduced in size.

  In particular, in recent years, power generation using natural energy (sunlight, wind power, etc.) has been promoted, and a direct current power source is easily generated in such a power generation apparatus. For this reason, by applying a DC power supply cable, a radiographic image can be taken with a DC power supply (a power source using natural energy). Further, the radiographic image capturing apparatus 310 can be effectively used even in an area where a DC power supply network is constructed. Of course, even when a DC power cable is used, power line communication can be performed by a power line communication device or the like applicable to a DC power line.

  Note that the present invention is not limited to the above-described embodiment, and it is needless to say that various configurations can be adopted without departing from the gist of the present invention.
