[First Embodiment]
First, a radiation imaging system according to the present invention will be described with reference to FIG. FIG. 1 is a schematic configuration diagram for explaining a radiation imaging system.

  The radiation imaging system 100 captures a radiation digital image (hereinafter referred to as a captured image). The radiation imaging system 100 performs inspection (imaging) based on an inspection order including a plurality of inspection information. The inspection information includes information for determining an imaging protocol, and each of the imaging protocols includes parameter information or imaging execution information used at the time of imaging or image processing, as well as, for example, the type of the imaging apparatus or the imaging posture. Such shooting environment information is specified. The inspection information includes information for specifying an inspection order, such as an inspection ID and a reception number, or specifying a captured image according to the inspection order.

  The radiation imaging system 100 includes a radiation imaging apparatus 200, a radiation generation control unit 110, a radiation imaging control unit 120, a display unit 121, an operation unit 122, and a radiation source 130. The radiation source 130 functions as a radiation generator. In the present embodiment, the radiation source 130 is an X-ray tube and irradiates the subject 140 (that is, the subject) with radiation (here, X-rays).

  The radiation generation control unit 110 controls the generation of radiation based on the imaging protocol in accordance with the control of the radiation imaging control unit 120. Specifically, the radiation generation control unit 110 generates radiation by applying a voltage to the radiation source 130 according to imaging conditions (for example, parameters such as tube current, tube voltage, and irradiation time) corresponding to the imaging protocol.

  The radiation imaging control unit 120 performs overall control of radiation imaging processing based on the imaging protocol. Further, the radiation imaging control unit 120 performs image processing on the captured image obtained from the radiation imaging apparatus 200. Image processing includes gradation processing, frequency processing, and the like, and is performed using image processing parameters according to the imaging protocol. In addition, the radiation imaging control unit 120 has a communication function of wired communication or wireless communication, or both.

  The display unit 121 displays information such as the system state to the operator. The display unit 121 is a display, for example, and can display an inspection order received from the outside, an inspection order created by an operator of the radiation imaging apparatus 200, or the like. The operation unit 122 receives an instruction from the operator. The operation unit 122 is configured using, for example, a keyboard, a mouse, or various buttons. The operator can input an imaging protocol based on the examination order or input an operation instruction to the radiation imaging apparatus 200 via the operation unit 122.

  Next, the flow of radiography of the subject 140 by the radiography system 100 will be described. When performing radiography of the subject 140, the operator places the radiation imaging apparatus 200 at a position where the radiation irradiated from the radiation source 130 and transmitted through the subject 140 is irradiated. Next, the operator activates the radiation imaging apparatus 200 and then operates the operation unit 122 to make the radiation imaging apparatus 200 ready for imaging. Subsequently, the operator operates the operation unit 122 to set radiation irradiation conditions for irradiation. After the above operation is completed, the operator confirms that each imaging preparation including the subject 140 is ready, presses the exposure switch provided in the operation unit 122, and the radiation generation control unit 110 is exposed to radiation. Direct shooting.

  Upon receiving the radiation exposure instruction, the radiation generation control unit 110 notifies the radiation imaging apparatus 200 of a signal indicating that radiation will be emitted. Note that when the radiation imaging apparatus 200 itself has a function of detecting radiation irradiation, the radiation generation control unit 110 does not need to notify the radiation imaging apparatus 200 of irradiation.

  When a signal to irradiate radiation is received from the radiation generation control unit 110 to the radiation imaging apparatus 200, the radiation imaging apparatus 200 confirms whether its own state is ready for radiation irradiation, and if there is no problem, permits irradiation. A response is made to the radiation generation control unit 110. When receiving the irradiation permission from the radiation imaging apparatus 200, the radiation generation control unit 110 drives the radiation source 130 to irradiate the radiation. When the radiation imaging apparatus 200 detects the end of radiation irradiation, the radiation imaging apparatus 200 detects radiation transmitted through the subject 140 as an electric charge corresponding to the amount of transmitted radiation, starts generation of a radiation image, and the generated radiation image is detected by the radiation imaging control unit 120. Send to. The end of radiation irradiation can be detected by various methods such as notification from the radiation generation control unit 110 or detection of the passage of the irradiation time determined in advance. The radiation imaging control unit 120 stores the radiation image received from the radiation imaging apparatus 200 in a storage medium or displays it on the display unit 121.

  Next, the configuration of the radiation imaging apparatus 200 will be described with reference to FIGS. 2 and 3. FIG. 2A is a perspective view of the radiation imaging apparatus 200 as viewed from the opposite surface (rear surface) of the radiation irradiation surface, and FIG. 2B is a block diagram illustrating each function of the radiation imaging apparatus 200.

  A radiation detection sensor 201 (radiation detection unit) is housed in the housing of the radiation imaging apparatus 200. The radiation detection sensor 201 detects the radiation transmitted through the subject S as a charge corresponding to the amount of transmitted radiation, and outputs it as an electrical signal corresponding to the charge. The electric circuit unit 202 takes in an electric signal output from the radiation detection sensor 201, performs a signal processing for convenience of transfer and post-processing, a function of supplying a power source for driving the radiation detection sensor 201, and the like Have The electric circuit unit 202 also has a function as a control unit that controls communication with the outside and the operation of each unit, and transmits images to other devices through communication, receives instructions from external devices, The activation / stop of the radiation imaging apparatus 200 is switched according to the operation of the person.

  A battery unit 203 is detachably attached to the back surface of the radiation imaging apparatus 200. The battery unit 203 is preferably configured so that it can be easily attached and detached, so that it can be replaced with a charged battery unit when the remaining battery level is low. The battery unit 203 is an element serving as a power source for driving each unit in the radiation imaging apparatus 200 including the radiation detection sensor 201, and is connected to the electric circuit unit 202 to supply power thereto.

  The wired connection interface 204 is connected to the wired communication unit 210 as necessary, and has a function of transmitting / receiving an electrical signal from the electrical circuit unit 202 to the outside. In some cases, the wired connection interface 204 has a power supply function. The wireless communication unit 205 performs wireless communication between the electric circuit unit 202 and the outside of the radiation imaging apparatus 200 when the radiation imaging system 100 is in a wireless communication network environment. Thereby, a communication form can be selected according to convenience between wired communication and wireless communication.

  Further, a switch 212 and a state display unit 211 are provided on the side surface of the radiation imaging apparatus 200. The switch 212 can be used for an operation of turning on / off the radiation imaging apparatus 200, an operation of switching an imaging enabled / disabled state (ready state), and the like. The status display unit 211 is configured using, for example, an LED, and displays the power on / off status, the remaining amount of the battery unit 203, and the like according to the color of the light, lighting / flashing / extinguishing status, and the like. Since the radiation imaging apparatus 200 is as thin as about 15 mm, it is difficult to display a lot of information on the state display unit 211. Therefore, a display unit 206 that displays information such as imaging patient information, imaging conditions, and the number of images that can be acquired is provided on the back of the radiation imaging apparatus 200.

  Further, a speaker that informs the state by sound so that the operator can recognize the state even when it is difficult for the operator to visually recognize the state display unit 211 and the display unit 206 such as when the radiation imaging apparatus 200 is under the patient. A unit 207 (sound generation unit) is provided on the back surface. The notification by the state display unit 211, the display unit 206, and the speaker unit 207 is controlled by the electric circuit unit 202. Note that when the switch 212, the status display unit 211, the display unit 206, and the speaker unit 207 are arranged in an adjacent region or a nearby region of the radiation imaging apparatus 200, the movement of the operator's line of sight or the like is small when operated. This is preferable.

  The volume control unit 208 controls the volume of sound emitted from the speaker unit 207. As for the volume, a standard volume level is set, and the volume can be adjusted automatically or manually. When the adjustment is performed automatically, the electric circuit unit 202 sets the volume based on various information. Here, the setting of the volume includes setting of a parameter relating to determination of the volume of the sound emitted from the speaker unit 207. The radiography control unit 120 may set the volume. When the volume is set by the radiation imaging control unit 120, information on the set volume is notified to the electric circuit unit 202 by wired communication or wireless communication, and the volume control unit 208 controls the volume based on the information. When the adjustment is performed manually, the radiation imaging control unit 120 sets the volume based on the input from the operation unit 122. The standard volume level and the adjusted volume level are saved as necessary. The storage unit 209 stores various parameters used for control of the radiation imaging apparatus 200 as electronic data. For example, you may memorize | store the parameter regarding a volume level.

  The processing related to the setting of the volume may be shared by the control unit of the electric circuit unit 202 and the volume control unit 208, or another control unit (for example, the radiation imaging control unit 120), or may be processed by one control unit. You may make it do. Moreover, CPU, MPU, FPGA, CPLD, etc. can be used also about the concrete mounting of each control part, and there is no restriction | limiting in particular.

  FIG. 3 is a view showing an AA cross section of FIG. A sensor panel 305 in which a photoelectric conversion element is formed on a glass substrate is disposed inside the radiation imaging apparatus 200. A phosphor 306 that converts radiation into visible light is formed on the surface of the sensor panel 305 on the photoelectric conversion element side. For the phosphor 306, CsI or the like is preferably used. When the radiation imaging apparatus 200 is irradiated with radiation, the phosphor 306 emits light, and the photoelectric conversion element of the sensor panel 305 converts the light into a small amount of charge signal. This charge signal is used for image formation. The method of converting radiation into electric charge is not limited to the above, and a direct conversion sensor that directly converts radiation such as a-Se into electric charge may be used. The charge signal generated by the sensor panel 305 is connected to the integrated circuit 308 through the flexible substrate 307. The integrated circuit 308 amplifies and A / D-converts a small amount of charge signal, and converts the charge signal into a digital image signal. The digital image signal is further processed in the electric circuit board 309 (corresponding to the electric circuit unit 202) and transferred to the radiation imaging control unit 120.

  Further, as described above, the radiation imaging apparatus 200 itself may have a function of detecting radiation irradiation (radiation irradiation detection function). There are various methods for realizing the radiation irradiation detection function. As an example, when the signal amount of the radiation irradiation signal generated in the sensor panel 305 due to the radiation irradiation exceeds a set threshold value, the radiation is emitted. There is a method for determining that the irradiation has occurred. Here, the radiation irradiation signal is a small amount of electric charge, and is amplified and A / D converted in the integrated circuit 308 or another integrated circuit (not shown) mounted on the electric circuit board 309. By determining whether the digital signal is equal to or greater than the threshold by the electric circuit unit 202, a radiation irradiation detection function is realized. Further, when radiation irradiation is detected by the electric circuit unit 202, a notification sound may be notified through the speaker unit 207.

  The sensor panel 305 has a rigid support plate 303 bonded to the opposite side of the radiation incident surface so that deformation or cracking does not occur due to external load or vibration during transportation. For the support plate 303, CFRP, magnesium alloy, aluminum alloy, or the like is used in order to achieve both strength and weight reduction. Further, a radiation shielding member (not shown) having a role of suppressing radiation deterioration of the electric circuit board 309 or removing scattered radiation from the back surface of the radiation imaging apparatus 200 is attached to the support plate 303 as necessary. The radiation shielding member is made of a high specific gravity material such as molybdenum, iron, or lead. The exterior of the radiation imaging apparatus 200 includes a radiation transmission plate 302 and a housing 301 that are disposed on the radiation irradiation surface. For the radiation transmitting plate 302, CFRP is preferably used in order to achieve both radiation transparency and rigidity. The casing 301 is made of CFRP, magnesium alloy, aluminum alloy, or the like in order to achieve both strength and weight reduction. A buffer material 304 is appropriately provided between the radiation transmitting plate 302 and the internal components, so that an effect of dispersing an external load and a buffering effect against an impact can be obtained. The material of the buffer material 304 is, for example, silicon or urethane-based foam material, silicon gel, or elastomer.

  On the electric circuit board 309, the sound producing component 312 and the detection unit 311 that constitute the speaker unit 207 are mounted. The sound producing component 312 can emit sound by, for example, an electrical signal, and a sound passage hole 313 (sound passage portion) is provided in a portion of the housing 301 facing the sound producing component 312. The speaker unit 207 is used as means for notifying a change in the state of the radiation imaging apparatus 200. For example, in the above-described radiation irradiation detection function, a notification sound may be used to notify when radiation irradiation is detected. Further, it may be notified by sound that a predetermined irradiation time has elapsed or the remaining battery level is low. Although FIG. 3 shows a configuration in which the sound producing component 312 is provided inside the housing and the sound is passed through the sound passage hole 313, the sound producing component 312 may be disposed near the surface of the housing.

  As described above, depending on the arrangement of the speaker unit 207 and the installation environment of the apparatus, the speaker unit 207 is blocked, so that the sound is attenuated and it may be difficult for the operator to hear the sound. For this problem, it is assumed that the volume is increased. However, particularly when the subject is closer to the radiation imaging apparatus 200 than the operator, there is a risk that a loud sound may be borne by the subject, so it is not preferable to increase the volume unnecessarily. Further, it is very troublesome for the operator to manually adjust the volume whenever the installation environment of the apparatus changes.

  Therefore, in the present embodiment, a detection unit for detecting whether there is an object (proximity object) approaching the vicinity of the speaker unit 207 is provided, and the volume of the notification sound is automatically set according to the detection result. A specific configuration will be described below.

  The detection unit 311 is configured using, for example, a proximity sensor, an ultrasonic sensor, an optical sensor, or the like, and detects the proximity of an object outside the radiation imaging apparatus 200. A through hole 314 is provided in a portion of the housing 301 that faces the detection unit 311. The sound passage hole 313 and the through hole 314 are arranged in the vicinity of the same surface of the housing 301 or are formed as an integral hole. With such a configuration, the detection unit 311 can detect whether or not the through hole 314 is closed depending on the installation environment, posture, and the like of the radiation imaging apparatus 200, and the volume based on the detection result The volume is set by the control unit 208. When the through-hole 314 is closed by an object outside the radiation imaging apparatus 200, there is a high possibility that the sound passage hole 313 provided near the through-hole 314 is also closed. Therefore, when it is determined that there is an adjacent object (the through hole 314 is blocked), the volume is larger than when it is determined that there is no adjacent object (the through hole 314 is not blocked). Is set so as to be notified.

  As shown in FIG. 3, when the sound passage hole 313 and the through hole 314 are arranged on the surface opposite to the radiation incident surface of the housing 301, the sound passage hole 313 is formed on a table or a bed, for example, in the case of taking a lying position. It will be in a state of being blocked by a futon. In this case, when the proximity object is detected by the detection unit 311, the sound volume control unit 208 is set to notify the sound at a volume larger than the normal volume in consideration of sound attenuation. Note that the volume setting may be changed according to the type of notification event in consideration of the burden on the subject 140 due to the increase in volume, and the volume may be set higher particularly in the case of notifications such as important warnings. .

  Further, the detection unit 311 may be a pressure sensor or the like directly configured on the housing 301. Also in this case, by disposing the pressure sensor in the vicinity of the sound hole 313, it is possible to determine whether or not the sound hole 313 is blocked according to the detected pressure value and to control the volume to be changed.

  Next, the flow of processing by the radiation imaging apparatus 200 having the above configuration will be described with reference to the flowchart of FIG. Hereinafter, a case where the volume of sound emitted from the speaker 207 by the electric circuit unit 202 will be described. However, as described above, the volume may be set by the radiation imaging control unit 120 or another control unit.

  When the radiation imaging apparatus 200 is activated, power is supplied to the electric circuit unit 202, and the electric circuit unit 202 is activated. Also, power is supplied to the other function units, and each function unit is activated. When the electric circuit unit 202 is activated, detection information by the detection unit 311 is acquired and transmitted to the volume control unit in step S501. The detection information may be a value itself detected by a sensor constituting the detection unit 311 or information indicating whether or not there is an adjacent object. When acquiring the value detected by the sensor itself, the electric circuit unit 202 may determine whether or not there is an adjacent object.

  In step S502, the electric circuit unit 202 sets the volume level of the sound to be generated by the sound generation component 312 based on the detection information acquired in step S501. As described above, the sound volume is set so that when a proximity object close to the through hole 314 (that is, close to the speaker unit 207) is detected, the sound is notified at a higher sound volume than when it is not detected. . When the radiography control unit 120 sets the sound volume, the proximity object detection information is received from the electric circuit unit 202 using wired communication or wireless communication, and the sound volume information set based on the detection information is electrically stored. It is assumed that the data is transmitted to the circuit unit 202.

  When the volume level is set in step S502, a sound generation request interrupt is permitted in step S503. As a result, when an interrupt signal requesting the execution of sound generation is generated, the volume control unit 208 controls the sound generation component 312 to generate sound according to the volume level set in step S502. In step S504, radiation is emitted in accordance with the operation of the operator, and imaging is performed.

  Next, an example of processing when radiography is performed using the radiation irradiation detection function will be described with reference to the flowchart of FIG. The processing up to step S602 is the same as the processing up to step S502 in FIG.

  In step S603, the electric circuit unit 202 starts radiation irradiation detection in response to an input from the operation unit 122 by the operator. In addition, prior to the start, it is assumed that necessary functional units are energized or activated. Here, the start of radiation irradiation detection may be notified by sound or light. When radiation irradiation detection is started, the radiation imaging apparatus 200 enters a radiation detection waiting state.

  In step S604, the electric circuit unit 202 determines whether radiation irradiation has been detected. If radiation irradiation is detected, the process proceeds to step S605, and if not detected, the process proceeds to step S607.

  In step S607, the electric circuit unit 202 determines whether or not a predetermined time has elapsed since the start of radiation irradiation detection, that is, whether or not the detection time has timed out. This detection time timeout is provided in order to end the radiation irradiation detection in preparation for the case where the detection time is left without irradiation. If the detection time has timed out, the process proceeds to step S608. If the detection time has not timed out, the process returns to step S604 to continue detection of radiation irradiation.

  In step S608, the electric circuit unit 202 causes the sound generation component 312 to generate a sound according to the volume level set in step S602, notifies the timeout, and ends the radiation irradiation detection. In FIG. 6, the sound is notified when the detection time has timed out, but the sound may be notified when the remaining time until the time-out reaches a predetermined time.

  On the other hand, when radiation irradiation is detected in step S604, in step S605, the electric circuit unit 202 generates sound in the sound generation component 312 according to the volume level set in step S602, and notifies the detection of radiation irradiation. Ends detection of radiation exposure. In step S606, shooting is performed.

  5 and 6, it is assumed that the volume level is set immediately after the radiation imaging apparatus 200 is activated, but the timing for setting the volume level is not limited to this. When the notification regarding the radiation irradiation detection is performed by sound as shown in FIG. 6, the volume level is set when, for example, the operator is instructed to shift to the mode for performing the radiation irradiation detection before the start of the radiation irradiation detection. You may make it perform.

  As described above, in the present embodiment, in the radiographic apparatus capable of sound notification, a detection unit that detects a proximity object is provided in the vicinity of the speaker unit, and the volume is set based on detection information from the detection unit. Specifically, when it is detected that there is an adjacent object, a louder volume is automatically set than when it is not detected. Thereby, it is possible to make a notification at an appropriate volume according to the installation environment and installation state of the radiation imaging apparatus.

  FIG. 4 is a perspective view of the radiation imaging apparatus 400 according to the present embodiment as seen from the radiation irradiation surface. A speaker unit 402 is provided on the housing 401 of the radiation imaging apparatus 400. In FIG. 4, a configuration in which the speaker unit 402 is provided on the side surface of the housing 401 is shown, but the arrangement of the speaker unit 402 is not limited thereto, and may be arranged on the back surface, for example. An attitude detector 403 is provided inside the radiation imaging apparatus 400. The posture detection unit 403 is configured using, for example, a gyro sensor (angular velocity sensor) and detects the posture of the radiation imaging apparatus 400.

  In the present embodiment, the storage unit 209 is registered in advance with the positional relationship between the three-axis direction of the posture detection unit 403 and the speaker unit 402. Thereby, the volume of the sound emitted from the speaker unit 402 can be set according to the direction of the radiation imaging apparatus 400 detected by the posture detection unit 403. Specifically, based on the detected orientation of the radiation imaging apparatus 400 and the positional relationship between the speaker unit 402 and the surface on which the speaker unit 402 is disposed becomes a lower surface (a state facing downward in the direction of gravity), The sound volume control unit 208 is set so as to increase the sound volume, assuming that the sound is reduced due to sound insulation. Note that the sound volume setting using the posture detection unit 403 may be used together with the sound volume setting in the first embodiment, or only one of them may be used.

  Further, the volume may be set according to the combination with the shooting conditions. For example, when the radiation imaging apparatus 400 is incorporated into a supine position imaging apparatus or the like used for imaging the subject's supine position, the surface on which the speaker unit 402 is provided is blocked by the apparatus. In the case of, the volume is set to be larger. In another example, when the head is photographed, if the posture of the speaker unit 402 is not blocked, the volume is set to be smaller. In this manner, by setting the volume according to the combination of the selected shooting condition and the posture detected by the posture detection, a more appropriate volume setting can be performed.

  As described above, in the present embodiment, in the radiographic apparatus capable of sound notification, the attitude detection unit that detects the attitude of the radiographic apparatus is provided, and the volume is set based on the detected attitude. Specifically, based on the attitude of the radiation imaging apparatus, it is determined whether or not the surface on which the speaker unit is provided is facing a predetermined direction. If the surface is facing the predetermined direction, a larger volume is automatically set. Set. As a result, it is possible to notify the operator at an appropriate volume regardless of the installation environment or installation state of the radiation imaging apparatus.
