An apparatus that irradiates an object with radiation and detects the intensity distribution of the radiation that has passed through the object to obtain a radiation image is widely used in industrial nondestructive inspection and medical diagnosis. A film/screen method and a CR method are typical methods for such photographing. In all of these, a photosensitive film or a phosphor plate that accumulates an image as a latent image is put in a storage case called a cassette standardized by Non-Patent Document 1 and used for photographing.

On the other hand, due to recent advances in digital technology, a method of obtaining a high-quality radiation image by converting the radiation image into an electric signal, performing image processing on the electric signal, and reproducing the visible image on a CRT or the like has become widespread. There is. FIG. 9 is a conceptual diagram showing a system using such a radiation image capturing apparatus. Reference numeral 103 is a radiation image capturing apparatus having a built-in radiation detection sensor 104. When the subject 102 is irradiated with the radiation emitted by the radiation generator 101, the radiation transmitted through the subject is converted into visible light through the phosphor, and the radiation detection sensor 104 photoelectric conversion elements arranged in a two-dimensional lattice form. It is detected as an electric signal. A control unit 105 that controls reading drive, image transfer, and the like is connected to the radiation image capturing apparatus 103, performs digital image processing on the image output from the radiation image capturing apparatus 103, and monitors the radiation of the subject on the monitor 106. Display the image.

Conventionally, this type of imaging device has been installed and used in a radiation room. However, in recent years, a thin and lightweight portable imaging device (referred to as an electronic cassette) has been developed in order to enable more rapid and wide-area imaging. As a result, an imaging system has been proposed which is applied not only to cassette imaging in a radiation room but also to the field of rounds (Patent Document 1 (page 2-3, FIG. 1)).

(Photographing department)
In FIG. 1, reference numeral 1 denotes a radiation image detection panel, which includes a fluorescent plate 1a, a photoelectric conversion element 1b, and a substrate 1c. As the substrate 1c, a glass plate is often used because it has no chemical action with the semiconductor element, can withstand the temperature of the semiconductor process, and needs dimensional stability. The photoelectric conversion elements 1b are formed in a two-dimensional array on the glass substrate 1c by a semiconductor process. The fluorescent plate 1a is a resin plate coated with a phosphor of a metal compound, and is integrated with the substrate 1c by adhesion.

The fluorescent plate 1a, the photoelectric conversion element 1b, and the substrate 1c are fixedly supported by the metal base 2 as the radiation image detection panel 1 to ensure mechanical strength. Reference numeral 3 is a circuit board on which an electronic component 3a for processing the electric signal converted by the photoelectric conversion element 1b is mounted. The circuit board 3 is connected to the photoelectric conversion element 1b by the flexible circuit board 4, and is fixed to the protrusion 2a provided on the back side of the base 2. The base 2 is fixed to the housing main body 5a via the support portion 2b, and is sealed by the radiation-transparent housing lid 5b, and the imaging unit 10 is configured as an electronic cassette.

Further, the photographing unit 10 includes a battery 6 that supplies power to the circuit board 3 and the like, and a wireless communication unit 7 that carries out signal transmission of image signals, control signals, and the like. The battery 6 is built in the photographing unit 10, and the photographing unit exterior 5a has an electrical contact terminal 6b for charging the battery 6.

(Mobile imaging device)
Such an imaging unit 10 is used as a mobile imaging device (moving radiation imaging device) 20 in combination with a mobile radiation generating device for rounds. The configuration of the mobile imaging device 20 according to this embodiment will be described with reference to FIG. A mobile imaging device 20 main body (hereinafter referred to as “main body”) 21 has a bottom portion 22 provided with a plurality of wheels 23 and 24, and can be arbitrarily moved. The main body 21 has a detection unit 25 that detects the rotation of the wheels 24, and has a function of detecting the moving state of the mobile imaging device 20. The detection means 25 can be realized by a simple structure such as a rotary encoder. On the other hand, in the front of the main body 21, there is provided a vertical support column 26 that is rotatably supported around an axis, and an arm 27 that extends horizontally with respect to the support column 26 and is supported so as to be movable in the vertical direction. It is equipped. A radiation generator 28 including a radiation tube is attached to the tip of the arm 27. The radiation generation unit 28 is movable in the horizontal direction along the arm 27, and the irradiation direction of the radiation can be arbitrarily adjusted.

The main body 21 is provided with a storage unit 30 for storing the image capturing unit 10. The image capturing unit 10 is stored during movement and is taken out from the storage unit 30 for use. Further, inside the main body 21, a control unit 32 that controls a tube for radiation irradiation, control of the mobile imaging device 20, and imaging control with the imaging unit 10, and a battery 31 that supplies necessary power to various units. Have. The control unit 32 includes a communication unit for communicating with the imaging unit, a unit for storing information such as images, an input/output unit, an interface for interlocking the radiation generator with the imaging unit, a power output control unit, and a controller for controlling these. Have. The operation of the control unit 32 is executed based on a computer program.

The input/output unit 33 used for the user's operation of the mobile imaging device 20 is composed of a monitor for display output and a device for input, and is arranged on the upper portion of the main body 21. The input device may be, for example, a button of a selection key for switching the selection position on the monitor or a touch panel. On the display unit, an operation menu is displayed for selecting the imaged region and transitioning the imager to the imageable state, and for setting the image capturing conditions such as the tube voltage and tube current of the generator and the irradiation time. Photography is performed in response to the user selecting an item on the input device. In addition, a series of operations for performing processing such as trimming and rotation on the captured image and storing it in the image recording means built in the control unit 32 is performed using the input device. Further, means for managing the information of the ordered patient, the imaging conditions, and the imaging history is provided, and is composed of a software module incorporated in the control unit 32. The operator can check the list of patient information and the like from the input/output unit 33. These pieces of information are operated by communicating with an external terminal in the hospital via the external communication means 34 connected to the control unit 32.

When taking a picture, the radio communication means 35, which communicates exclusively with the radio communication section 7 built in the photographing section 10, is used. Under the conditions set by the input/output unit 33, an imaging command is sent from the control unit 32, and an image taken in synchronization with the radiation tube of the radiation generation unit 28 is transmitted. The captured image is stored in the memory in the control unit 32 and finally transferred to the external terminal.

Further, the main body 21 is provided with a receiving means 36 for receiving information for recognizing the wireless restriction. A mechanism for recognizing the wireless restriction based on the information from the transmitting means provided outside and limiting the communication by the communication means 34, 35 is provided. In this embodiment, as shown in FIG. 3, the gate 40 provided on the wall surface of the facility is provided with the transmitting means 41 for notifying the switching of the wireless restricted area, and the receiving means 36 receives the signal when passing through the gate. It recognizes the switching of the wireless restricted area. Here, the wireless restricted area refers to an area where the wireless communication function of the mobile imaging device 20 should be restricted in order to suppress the influence of electromagnetic waves on medical devices, biological devices, and the like. Such wireless restricted areas include, for example, areas in and around medical/institutions such as hospitals and laboratories where measurement/inspection devices and medical devices that can be affected by electromagnetic waves are installed/used. For example, in the floor of the hospital with the layout shown in FIG. 4, the hatched area A1 in FIG. 4 is a space where devices susceptible to wireless communication are installed, and wireless restrictions are applied. It is a restricted wireless area. On the other hand, hospital rooms for inpatients are in areas A2 and A3, and wireless communication is required here for round-trip imaging. Therefore, the gates 40 and 42 are arranged near the entrances of the areas A2 and A3 to transmit the restricted area switching signal. In this way, the mobile imaging device 20 recognizes the intrusion into the wireless restricted area in response to receiving the signal indicating the existence of the wireless restricted area from the outside from the transmitting unit 41 which is an external device. As a result, wireless communication can be restricted in response to the reception of this signal. That is, the mobile imaging device 20 acquires the information that specifies the wireless restricted area, and restricts the wireless communication function according to the information.

(Processing procedure)
A workflow when the mobile imaging device 20 as described above is used will be described with reference to the flowchart of FIG. Hereinafter, the processing executed by the mobile imaging device 20 is executed under the control of the control unit 32.

As a preparation procedure, when the user connects an AC cable (not shown) for operating the mobile imaging device 20 to a commercial power source, the mobile imaging device 20 charges the main body battery 31 with electric power in advance (S100). Order information from the RIS terminal in the hospital is uploaded to the control unit 32 of the mobile imaging device 20 via an external communication unit (not shown) (S101). The transferred information is displayed as a list on the input/output unit 33 (S102), and the technician as the user confirms the information (S103), and at the same time, plans a rough schedule for round-trip imaging in consideration of priority and movement route ( S104). The displayed contents include patient information such as patient name and sex, hospital room number, and imaging requirements such as imaging site and imaging posture. Then, the AC cable is removed upon completion of charging (S105). If the imaging unit 10 is not mounted on the main body 21, it is mounted (S106).

When the preparation is completed, the user starts moving to a predetermined hospital room while pressing the mobile imaging device 20 according to the scheduled schedule (S107). At this time, the counter value of the control flag Nf for recognizing the radio restriction is reset to 0. The mobile imaging device 20 monitors passage through the gate during movement (S108). If the gate passage is detected (YES in S108), the process proceeds to S109, and if the gate passage is not detected (NO in S108), the process proceeds to S110. In the present embodiment, when the receiving unit 36 receives the restricted area switching signal from the transmitting unit 41 of the gate 40 (YES in S108) in response to the passage through the gate, the signal is transmitted to the control unit 32, and the counter is set in the control unit 32. One is added to the value Nf (S109). The counter value Nf is a binary flag, and when 1 is added when Nf=1, Nf=0.

Next, in S110, it is determined whether the counter value Nf is 1 (S110). When Nf=1 (YES in S110), wireless communication is limited (S111), and the process proceeds to S115. If Nf=0 (NO in S110), the restriction on wireless communication is released (S112), and shooting (S113) is enabled.

For example, consider a case where the mobile imaging device 20 exits from the elevator entrance/exit 45 of the floor of FIG. 4 using an elevator from the imaging base of another floor. When leaving the base station, Nf=0, but before the floor is reached in FIG. 4, the restricted area switching signal is received, the counter value Nf is set to 1, and the wireless limit Nf=1 is displayed. Suppose you moved to the 4th floor. Since the passage area including the elevator hall is adjacent to the area A1 where the influence of radio waves is strong, the movement is still performed while maintaining the radio restriction. When moving further, the gate 40 is arranged in order to perform a round trip radiographing in the ward A2. When a restricted area switching signal is obtained from the gate 40, the counter value becomes Nf=0 and the wireless restriction is released. In this way, since the restriction on the wireless communication function is released in response to the recognition of the exit from the wireless restricted area, the wireless communication becomes possible again thereafter. For example, it is possible to collectively send images taken in a state where wireless communication is restricted to the server device.

As a method of limiting the wireless communication, for example, in addition to disabling the wireless communication function, a time zone in which the wireless communication function can perform communication, an interval of communication, a communication data amount, and a communication power within a certain range. It is possible to limit it to. The system designer can select an appropriate restriction method according to the requirements of the wireless restricted area.

When the patient arrives at the predetermined hospital room and stops, the position of the radiation generating unit 28 is adjusted with respect to the predetermined photographing posture, and then the photographing region on the display unit is selected to set the photographing conditions such as the tube voltage of the generator and the mAS value. Set. When the conditions are met, shooting is performed (S113). When the shooting is completed, the shooting unit 10 is returned to the storage unit 30 and the list is automatically updated to reflect that the shooting is completed as the management information (S114). The imaging order is checked (S115), and if the order remains ("remaining" in S115), the procedure moves to the next hospital room and the series of flow is repeated. When the shooting order is exhausted (“No” in S115), the mobile imaging device 20 is returned to a predetermined standby base. When the mobile imaging device 20 arrives at the base (YES in S116), at the same time, the processing result of the imaging order is output to the RIS (S117), and the round-trip imaging ends.

As described above, the mobile imaging device 20 of the present embodiment limits the wireless communication function in response to the recognition that the imaging device has entered the wireless restricted area. Therefore, according to the configuration of the present embodiment, it is possible to appropriately limit the wireless communication without requiring a complicated work such as the user confirming the entry into the wireless restricted area and disabling the wireless communication function. .. In addition, in the present embodiment, the configuration example of the mobile radiation imaging apparatus has been described as an example of the medical imaging apparatus having the wireless communication function, but the present invention is not limited to this, and another type having a wireless communication function is provided. Needless to say, it can be applied to medical devices of.

<<Embodiment 2>>
In the first embodiment, the configuration example in which the wireless communication control area is recognized by receiving the restricted area switching signal from the transmission means provided in the gate has been described. In the present embodiment, a configuration example will be described in which the current position is recognized based on the detection result of the rotation of the wheel 24 by the detection unit 25, and the entry into the wireless communication control area is determined. FIG. 6 is a diagram showing a configuration example of a mobile radiographic apparatus (mobile radiographic apparatus) according to the second embodiment of the present invention. Most of the configurations according to the present embodiment are the same as the configurations of the first embodiment, and therefore the differences from the first embodiment will be mainly described.

In FIG. 6, a mobile photographing device 50 combined with the photographing unit 10 is shown. A current position recognizing means 51 for grasping the current position is provided inside the main body 21 of the mobile imaging device 50, and sequentially transmits information about the current position to the control unit 32. The current position recognizing means 51 also includes information from the detecting means 25 for detecting the rotation of the wheel 24 as the moving means, the detecting means 52 for detecting the moving direction, and the detecting means 53 for detecting the moving in the gravity direction. In addition, the relative position change and the movement amount are calculated, and the current position is recognized. As described above, the current position recognizing unit 51 determines the current position based on the detected movement amount of the mobile imaging device 50, and when it is determined that the current position belongs to the wireless restricted area, Recognize intrusion. As described above, in the present embodiment, the mobile imaging device 20 acquires the information that specifies the wireless restricted area based on the moving amount of the mobile imaging device 50, and restricts the wireless communication function according to the information. There is. It should be noted that such information may be acquired based on a GPS signal, information from a network, or the like, as described later.

On the other hand, similarly to the first embodiment, an input/output unit 33 including a monitor and an input device is provided on the upper portion of the main body 21. The input/output unit 33 can be used to set a wireless restricted area. The control unit 32 stores in-hospital map information and has a function of displaying a map on the input/output monitor 60 as shown in FIG. The map is created for each floor, and it is possible to switch and confirm by using the tab 61. Further, it has a function of inputting and editing wireless control area information, and can switch to the input/edit mode in response to selection of the edit button 62. As shown in FIG. 7, the wireless restricted area can be defined by defining the wireless prohibited area A1 as a hatched portion. In this way, by displaying the map of the predetermined area on the monitor, performing the reception process for receiving the selection from the user on the map, and setting the area selected by the user as the wireless restricted area, the user can perform a simple operation. You can set the wireless restricted area with.

Further, it is also possible to define the level of wireless restriction in stages such as a level for invalidating wireless communication and a level for suppressing the frequency of wireless communication. That is, the wireless restricted area is composed of partial areas to which respective levels for restricting wireless communication are allocated, and the level for restricting the wireless communication function is controlled according to the level allocated to the partial area where the photographing device exists. Can be configured to. As a result, the wireless communication can be finely restricted according to the level at which the wireless communication should be restricted.

In addition, a marker 63 that displays the current location is displayed on the monitor 60, and the positional relationship with the wireless restricted area can be confirmed on the monitor. A wireless restriction rule can be set in advance. For example, it is possible to manage the wireless communication by restricting the wireless communication within a radius of a few meters of the wireless prohibited area or stopping the wireless communication when the wireless prohibited area is actually invaded. By having such a function, wireless communication can be automatically managed without the operator being aware of it, and troubles due to wireless communication can be prevented.

By setting the level that suppresses the frequency of wireless communication described above, instead of disabling wireless communication, by making a rule to control the communication frequency, the time delay for information update is reduced, Flexibility in handling urgent orders can be improved.

<<Embodiment 3>>
The third embodiment shown in FIG. 8 is a modification of the second embodiment. The same parts as those in the second embodiment are described with the same reference numerals. The mobile radiation imaging apparatus according to the second embodiment uses the current position recognizing unit 51 as a positioning unit. This is an autonomous navigation in which the relative position change is calculated based on the information from the movement by each detecting means that detects the rotation of the wheel 24 or detects the movement in the moving direction or the gravity direction to obtain the current position. It was a type of positioning means. At present, positioning technology has advanced, and positioning means using signals from satellites such as GPS and positioning means using wireless network are generally used, and the detection position accuracy is improving. The mobile radiation imaging apparatus of FIG. 8 in the present embodiment is equipped with the positioning means 71 using such radio waves.

In the case of the above-mentioned autonomous navigation type positioning means, since relative positions are calculated and integrated, there is a possibility that position errors will gradually occur, and fairly accurate detection capability is required. On the other hand, the positioning means using radio waves detects the relative position from the known position each time, and therefore the error is not accumulated. Usually, the position can be accurately grasped by using the positioning means using this radio wave. However, if there is a wireless restriction, the usage is restricted, and the position detection accuracy is degraded. In that case, the present position recognition means 51 is used as an autonomous navigation type. The position can be corrected by using the positioning means by radio waves when the wireless restriction is released.

As described above, in the present embodiment, the positioning device includes the measuring device that measures the position by the received radio wave and the autonomous navigation positioning device, and it is recognized that the imaging device is invading the wireless restricted area. During this period, only the autonomous navigation type positioning means is used. Therefore, it is possible to achieve both the restriction of wireless communication in the wireless restricted area and the accurate grasp of the current location.

According to each of the above-described embodiments, it is possible to comply with wireless restrictions and suppress the influence on other devices in the hospital without the operator being aware. It goes without saying that the radiation image capturing apparatus according to the above-described embodiment can be variously modified without departing from the scope of the claims.
