[0026] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings.

[0027] Fig. 1 is a diagram showing a schematic configuration of a radiation imaging system 1. As shown in Fig. 1, the radiation imaging system 1 includes an imaging device 10 and a console 30. The imaging device 10 and the console 30, and the console 30 and an external RIS (Radiology Information System) 50 are communicably connected via a wired or wireless network.

[0028] The console 30 acquires imaging orders and the like from the RIS 50. The console 30 also controls the imaging device 10 in accordance with the acquired imaging order and settings and instructions specified by the user to perform radiation imaging processing. When the radiation imaging processing starts, the imaging device 10 performs radiation imaging by irradiating radiation onto the subject H in accordance with the control of the console 30 and acquiring a radiation image of the subject H. The console 30 is an example of an "information processing device."

[0029] The console 30 is operated by a person who operates the imaging apparatus 10, such as a radiologist. A radiologist is an example of a "user." The radiation imaging system 1 may be configured to include a PACS (Picture Archiving and Communication Systems), not shown.

[0030] Next, the imaging device 10 will be described with reference to Fig. 2. Fig. 2 is a diagram showing a schematic configuration of the imaging device 10. Fig. 2 shows an example of how radiation imaging is performed on the chest of a patient, which is an object H, as the imaging region.

[0031] As shown in Fig. 2, the imaging device 10 includes a radiation irradiator 11 and a radiation detector 15. The radiation irradiator 11 includes a radiation source 12 that irradiates radiation such as X-rays, and an optical camera 13. The optical camera 13 is an example of an "imaging device." The radiation detector 15 is an example of an "image receiving unit."

[0032] When a user issues an instruction to irradiate radiation, the imaging device 10 irradiates radiation from the radiation source 12. A range R shown in FIG. 2 indicates the region to be irradiated with radiation. The range R can be adjusted variably by the user. The type of radiation source 12 is not particularly limited, and for example, a hot cathode type or a cold cathode type radiation source can be used as appropriate.

[0033] The optical camera 13 is an optical digital camera that captures images based on visible light and includes, for example, a CMOS (Complementary Metal Oxide Semiconductor) image sensor or a CCD (Charge Coupled Device) image sensor. A 2D camera such as a color camera, or a 3D camera equipped with a color camera and a depth camera can be used as the optical camera 13. The optical camera 13 is capable of capturing still images and moving images. The optical camera 13 captures images of the surroundings of the radiation irradiation unit 11 and can acquire, in real time, visible light images and depth images corresponding to the visible light images.

[0034] In the radiation imaging system 1, the movements of people, objects, etc. included in the images and videos acquired by the optical camera 13 can be detected using, for example, inter-frame difference, optical flow, and a posture estimation system.

[0035] Furthermore, in the radiation imaging system 1, the presence of people, objects, and the like included in the images and videos acquired by the optical camera 13 can be detected using, for example, a human body detection system, a posture estimation system, and the like.

[0036] The optical camera 13 can capture an image of an area wider than the area R shown in FIG. 2, for example, the area C shown in FIG.

[0037] There is no particular limitation on the location where optical camera 13 is installed. For example, as shown in Fig. 2, optical camera 13 may be attached to the same surface as the radiation irradiation opening of radiation irradiation unit 11. Alternatively, optical camera 13 may be attached to the wall of the imaging room.

[0038] The radiation detector 15 detects, on a detection surface 15A, the radiation that has passed through the subject H. The radiation detector 15 generates a radiographic image based on the detected radiation, and outputs the generated radiographic image to, for example, the radiation irradiation unit 11 and the console 30.

[0039] The radiation detector 15 is, for example, a portable electronic cassette, and may be placed on any pedestal or held by the subject H. The radiation detector 15 may be movable to any position in the horizontal direction (X direction and Y direction) and vertical direction (Z direction) relative to the radiation irradiator 11. The radiation detector 15 may also be a stationary type that is placed inside an imaging table installed in an imaging room.

[0040] There is no particular limitation on the type of radiation detector 15. The radiation detector 15 may be an indirect conversion type radiation detector that converts radiation into light and then converts the converted light into an electric charge, or a direct conversion type radiation detector that directly converts radiation into an electric charge.

[0041] The radiation irradiator 11 may be a ceiling-traveling type irradiator that is supported by a support column suspended from the ceiling of the radiography room. The ceiling-traveling type irradiator has a support column that is extendable in the vertical direction (Z direction) and attached via wheels to rails that run around the ceiling, and is movable horizontally (X direction and Y direction) within the radiography room. The horizontal movement and vertical extension / contraction of the support column causes the radiation irradiator 11 to translate horizontally and vertically. The radiation irradiator 11 may also be rotatable around a rotation axis that extends horizontally or around a rotation axis that extends vertically.

[0042] Furthermore, the radiation irradiator 11 may be, for example, a portable irradiator. The portable irradiator may be used, for example, for simple radiological examinations in medical facilities, radiological examinations in home medical care, radiological examinations outdoors, or for on-site medical care in disaster areas or medically underserved areas. Furthermore, for example, the radiation irradiator 11 may be a stationary irradiator installed in an imaging room. The operation of the radiation irradiator 11 is controlled by the console 30.

[0043] 3 is a diagram showing an example of the hardware configuration of the console 30 that controls the operation of the radiation irradiation unit 11 and the operation of the imaging device 10. For the purpose of explanation, FIG. 3 also shows part of the hardware configuration of the imaging device 10.

[0044] The console 30 includes a CPU (Central Processing Unit) 31, memory 32 such as ROM (Read Only Memory) and RAM (Random Access Memory), a storage unit 33, a display 34, an operation unit 35, and an I / F (Interface) unit 36.

[0045] The CPU 31 loads various programs including the information processing program 100 stored in the storage unit 33 into the memory 32 and controls each component included in the radiation irradiation unit 11 .

[0046] The display 34 displays in real time the images and videos captured by the optical camera 13. The display 34 may also display the radiation image generated by the radiation detector 15.

[0047] The I / F unit 36 ​​is an interface for communicatively connecting each component included in the imaging device 10 to the console 30. The I / F unit 36 ​​is also an interface for communicatively connecting the console 30 and the RIS 50.

[0048] The CPU 31 can control the turning on and off of the light emitting unit 14 provided in the radiation emitting unit 11. The user can turn on the light emitting unit 14 and determine the position of the range R of the radiation irradiation area, etc.

[0049] The light irradiation unit 14 is provided with, for example, a timer (not shown). After the light irradiation unit 14 starts to turn on, the timer starts counting, and after a predetermined time, such as 30 seconds, has elapsed, the light irradiation unit 14 automatically turns off. The light irradiation unit 14 is an example of "lighting." The light irradiation unit 14 is configured with an LED (Light Emitting Diode) light, an LD (Laser Diode) light, or the like.

[0050] The operation unit 35 is an interface between the user and each component of the console 30 and the imaging device 10. The light irradiation unit 14 can be turned on and off by switches provided on the console 30, the imaging device 10, etc.

[0051] The console 30 can acquire patient information from the RIS 50 and display the acquired patient information on the display 34. A user can input information about the patient who will be the subject H, etc., into the console 30 and acquire the patient information from the RIS 50. The CPU 31 is an example of a "processor."

[0052] Next, the processing of the information processing program 100 executed by the CPU 31 will be described with reference to FIG.

[0053] FIG. 4 is a flowchart showing an example of processing executed by the CPU 31 in accordance with the information processing program 100.

[0054] In step S100, the CPU 31 receives setting information from the user. Here, the setting information includes various settings in the imaging device 10 when imaging the subject H, such as an imaging menu and an illumination control mode for controlling the on / off of the light irradiation unit 14. The setting information is registered by the user. The setting information also includes information on the patient who will be the subject H. The setting information is registered in, for example, the console 30.

[0055] In the imaging menu, the user can register the body parts of the patient to be imaged, such as the head, chest, abdomen, and legs, which will be the subject H to be imaged. In the illumination control mode, the user can select and register whether to use the first mode as the illumination control mode for controlling the on / off of the light irradiator 14. According to the illumination control in the first mode, the on / off of the light can be controlled using an image acquired from the optical camera 13. Details of the control of the light irradiator 14 in the first mode will be described later (see FIG. 5). Regardless of whether the first mode is set, the user can control the on / off of the light irradiator 14 by operating the operation unit 35. Control of the on / off of the light irradiator 14 in a mode other than the first mode, in other words, a mode in which the on / off of the light irradiator 14 is controlled by operating the operation unit 35 without using an image, will be referred to as the second mode hereinafter. Details of the control of the on / off of the light irradiator 14 in the second mode will be described later (see FIG. 6).

[0056] In step S102, the CPU 31 receives an instruction to start the examination. The instruction to start the examination is given, for example, by the user operating the console 30. When the instruction to start the examination is received, the CPU 31 starts the radiation imaging process by the radiation imaging system 1.

[0057] In step S104, the CPU 31 determines whether or not the first mode is set in the setting information as the control mode of the light irradiation unit 14. If the first mode is set, the CPU 31 makes a positive determination. If the determination is positive, the CPU 31 executes the process of step S106. If the first mode is not set, the CPU 31 makes a negative determination and executes the process of step S108.

[0058] In step S106, the CPU 31 changes the control mode of the light irradiation unit 14 to the first mode.

[0059] In step S108, the CPU 31 determines whether radiation has been irradiated. An instruction to irradiate radiation is given by the user. If radiation has been irradiated, the CPU 31 makes a positive determination in step S108. If radiation irradiation has not been completed, the CPU 31 makes a negative determination in step S108.

[0060] If the determination in step S108 is positive, the CPU 31 executes the process of step S110. If the determination in step S108 is negative, the CPU 31 executes the process of step S108.

[0061] In step S110, the CPU 31 acquires the radiographic image generated by the radiation detector 15.

[0062] In step S112, the CPU 31 determines whether the control mode of the light irradiation unit 14 is set to the first mode. The case where the control mode of the light irradiation unit 14 is set to the first mode is, for example, when the determination is affirmative in the processing of step S104. If the control mode of the light irradiation unit 14 is set to the first mode, the CPU 31 determines affirmative in the processing of step S112 and executes the processing of step S114. If the control mode of the light irradiation unit 14 is not set to the first mode, the CPU 31 determines negative in the processing of step S112 and executes the processing of step S116.

[0063] In step S114, the CPU 31 ends the control of the light irradiation unit 14 in the first mode.

[0064] In step S116, the CPU 31 receives an instruction to end the examination, for example, from a user. After receiving the instruction to end the examination, the radiation imaging process by the radiation imaging system 1 ends. The CPU 31 executes the process shown in FIG. 4 every time radiation imaging is performed.

[0065] By the above processing, when the control mode of the light irradiator 14 is set to the first mode, the CPU 31 can control the light irradiator 14 in the first mode while executing the processing from step S106 to step S110, for example. Under the control of the light irradiator 14 in the first mode, the user can determine the area to be irradiated with radiation and obtain a radiological image of the subject H.

[0066] Next, details of the process of controlling the light irradiation unit 14 in the first mode will be described with reference to Fig. 5. The process shown in Fig. 5 is executed by the CPU 31 when, for example, the determination in step S104 in Fig. 4 is positive.

[0067] In step S200, the CPU 31 acquires the video captured by the optical camera 13 in real time.

[0068] In step S202, the CPU 31 determines whether or not a lighting instruction indicating an instruction to turn on the light irradiation unit 14 has been received by the user operating the operation unit 35. If a lighting instruction has been received by the user operating the operation unit 35, the CPU 31 makes a positive determination and executes the process of step S206. If the operation unit 35 has not been operated and a lighting instruction from the operation unit 35 has not been received, the CPU 31 makes a negative determination and executes the process of step S204.

[0069] In the process of step S204, the CPU 31 determines whether or not at least one of the presence and movement of an object or person included in the acquired video has been detected.

[0070] In detail, for example, when the presence of an object or a person is detected in the acquired video, the CPU 31 makes a positive determination. As another example, when a specific person is present in the acquired video, the CPU 31 makes a positive determination. An example of a specific person is a patient who will become the subject H, or a user who operates the imaging device 10 when imaging an affected area, such as a radiologist. For example, when the movement of any person or any object included in the acquired video is detected, the CPU 31 makes a positive determination. As another example, when the CPU 31 recognizes a person, such as a patient who will become the subject H and a user, included in the acquired video and detects the movement of a predetermined specific person among the recognized people, the CPU 31 makes a positive determination. Here, the subject H, the patient who will become the subject H, and the user are examples of "objects." The patient who will become the subject H and the user are examples of "people."

[0071] As another example, when a gesture indicating a turn-on instruction is detected by any person included in the video or a recognized predetermined specific person, the CPU 31 makes a positive determination. Note that a gesture indicating a turn-on instruction is an example of a "specific movement." Note that the association between the turn-on instruction of the light irradiation unit 14 and the gesture is set in advance by the user and stored in, for example, the storage unit 33.

[0072] In the process of step S204, the detection target may be, for example, the presence and movement of objects, people, etc. included in the entire range C captured by optical camera 13. Alternatively, the detection target may be the presence and movement of objects, people, etc. included in a limited range, such as a portion of range C, for example, the range corresponding to radiation detector 15, and range R, which is the radiation irradiation area. With the above configuration, it is possible to prevent the lights from being turned on and off unnecessarily, compared to when the range for capturing images is not limited.

[0073] If a movement is detected in the process of step S204, the CPU 31 makes an affirmative determination and executes the process of step S206. If a movement is not detected in the process of step S204, the CPU 31 makes a negative determination and executes the process of step S202.

[0074] In step S206, the CPU 31 turns on the light emitting unit 14.

[0075] In the process of step S208, the CPU 31 determines whether or not a turn-off instruction indicating an instruction to turn off the light irradiation unit 14 has been received by pressing a switch provided on the operation unit 35 or the like. If a turn-off instruction has been received, the CPU 31 makes a positive determination and executes the process of step S210. If a turn-off instruction has not been received, the CPU 31 makes a negative determination and executes the process of step S218.

[0076] In the process of step S210, CPU 31 determines whether or not the movement of a person or object included in the acquired video has been detected. The details of the movement of a person or object included in the video are the same as those described in step S204, and therefore will not be described again.

[0077] If a movement is detected in the process of step S210, the CPU 31 makes an affirmative determination and executes the process of step S212. On the other hand, if a movement is not detected, the CPU 31 makes a negative determination and executes the process of step S218.

[0078] In the process of step S212, the CPU 31 determines whether or not a turn-off instruction has been received from the detected movement. For example, in the process of step S210, if a gesture is detected as the movement and the gesture indicates a turn-off instruction, the CPU 31 makes a positive determination. On the other hand, if the movement of a person included in the video is detected and the movement does not indicate a turn-off instruction, the CPU 31 makes a negative determination. Note that the association between the turn-off instruction for the light irradiation unit 14 and the gesture is set in advance by the user and stored in, for example, the storage unit 33.

[0079] If the determination in the process of step S212 is positive, the CPU 31 executes the process of step S218. If the determination in the process of step S212 is negative, the CPU 31 executes the process of step S214.

[0080] In the process of step S212, the detection target may be, for example, the presence and movement of objects, people, etc. included in the entire range C captured by optical camera 13. Alternatively, the detection target may be the presence and movement of objects, people, etc. included in a limited range, such as a portion of range C, for example, the range corresponding to radiation detector 15 and range R, which is the radiation irradiation area. With the above configuration, it is possible to prevent the lights from being turned on and off unnecessarily, compared to when the range for capturing images is not limited.

[0081] In step S214, the CPU 31 resets the count of the timer of the light irradiation unit 14.

[0082] In step S216, the CPU 31 determines whether a predetermined time has elapsed since the light irradiation unit 14 started to be turned on. An example of the predetermined time is a predetermined time, such as 30 seconds. If the predetermined time has elapsed, the CPU 31 makes a positive determination and executes the process of step S218. If the predetermined time has not elapsed, the CPU 31 makes a negative determination and executes the process of step S208.

[0083] In step S218, the CPU 31 turns off the light irradiation unit 14. While the process of Fig. 4 is being executed and control in the first mode continues, the CPU 31 repeatedly executes the process shown in Fig. 5.

[0084] As described above, by processing steps S200 to S218, the CPU 31 can control the turning on and off of the light irradiation unit 14 by the user pressing a switch, as well as control the turning on and off of the light irradiation unit 14 using images acquired by the optical camera 13.

[0085] In the processes of steps S204, S210, and S212, if the video contains multiple people, CPU 31 may be configured to detect and determine the movement of only a specific person, such as a user. With this configuration, if the video contains multiple people, it is possible to prevent the lights from being turned on or off due to movements other than those of a specific person.

[0086] Next, details of the control process of the light irradiation unit 14 in the second mode will be described with reference to Fig. 6. The process shown in Fig. 6 is executed by the CPU 31 while the process in Fig. 4 is being executed, for example. Note that if the determination in step S104 is positive, the process shown in Fig. 6 is not executed while the control in the first mode continues.

[0087] In step S300, the CPU 31 determines whether or not an instruction to turn on the light irradiation unit 14 has been received from the operation unit 35. When an instruction to turn on the light irradiation unit 14 has been received by pressing a button provided on the operation unit 35, for example, the CPU 31 makes an affirmative determination.

[0088] If the determination is affirmative, the CPU 31 executes the process of step S302. If the determination is negative, the CPU 31 executes the process of step S300.

[0089] In step S302, the CPU 31 turns on the light emitting unit 14.

[0090] In step S304, the CPU 31 determines whether or not it has received an instruction to turn off the light irradiation unit 14. If it has received an instruction to turn off the light irradiation unit 14 by, for example, pressing a button provided on the operation unit 35, the CPU 31 makes an affirmative determination.

[0091] If the determination is affirmative, the CPU 31 executes the process of step S308, whereas if the determination is negative, the CPU 31 executes the process of step S306.

[0092] In step S306, the CPU 31 determines whether a predetermined time has elapsed since the light irradiation unit 14 started to be turned on. The predetermined time is, for example, 30 seconds. If the predetermined time has elapsed since the light irradiation unit 14 started to be turned on, the CPU 31 makes a positive determination in step S306.

[0093] If the determination is affirmative, the CPU 31 executes the process of step S308. If the determination is negative, the CPU 31 executes the process of step S304.

[0094] In step S308, the CPU 31 controls to turn off the light irradiation unit 14. While the process of Fig. 4 is being executed, the process of Fig. 6 is repeatedly executed.

[0095] As described above, according to the processes of steps S300 to S308, the CPU 31 can control the turning on and off of the light irradiation unit 14, for example, by the user operating the operation unit 35. According to the second mode, the CPU 31 does not control the turning on and off of the light irradiation unit 14 using the image acquired by the optical camera 13.

[0096] 4 to 6, at least one of turning on and off of the light emitting unit 14 can be controlled by the user using the image captured by the optical camera 13. Furthermore, with the photographing device 10 equipped with the optical camera 13, the user can remotely control the turning on and off of the light emitting unit 14 without adding any dedicated input devices such as an ultrasonic distance sensor, an optical distance sensor, or an audio input microphone.

[0097] Furthermore, by controlling the light irradiating unit 14 based on the image (control of the light irradiating unit 14 in the first mode), the light can be automatically turned on in response to the presence of a person, compared to when the user turns on the light with a switch. Furthermore, by controlling the light irradiating unit 14 based on the image (control of the light irradiating unit 14 in the first mode), when the light used to determine the radiation emission range is automatically turned off by a timer, the user can easily turn the light on, compared to when the user turns the light on again with a switch.

[0098] Furthermore, by controlling the light irradiation unit 14 based on the video (control of the light irradiation unit 14 in the first mode), the user can easily control the turning on and off of the light remotely, compared to when the user turns on the light with a switch and automatically turns it off with a timer. Furthermore, by controlling the light irradiation unit 14 based on the video (control of the light irradiation unit 14 in the first mode), when multiple people are included in the video, it is possible to prevent the light from being turned on or off due to any reason other than the movement of a specific person.

[0099] Furthermore, by controlling the light irradiation unit 14 based on the image (controlling the light irradiation unit 14 in the first mode), it is possible to prevent the light from being turned on and off unnecessarily, compared to when the range in which the image is acquired is not limited.

[0100] Furthermore, according to a configuration in which the first mode can be set as the control mode of the light irradiation unit 14 in the setting information, the user can select whether to control the on / off of the light using the acquired image or to control the on / off of the light without using the acquired image.

[0101] In addition to the above, the timing for controlling the turning on and off of the light emitting unit 14 in the first mode may be configured to be appropriately changed by, for example, a user setting.

[0102] For example, when the imaging device 10 is in a state where imaging is possible, in other words, when radiation imaging is possible, the CPU 31 may be configured to be able to control the turning on and off of the light irradiation unit 14 in the first mode. The state where the imaging device 10 is in a state where imaging is possible refers to, for example, the period from when the user registers setting information on the console 30 until radiation irradiation begins. More specifically, this refers to the period from step S102 onwards to step S108 in FIG. 4 being executed. With the above configuration, it is possible to prevent the lights from being turned on unnecessarily, compared to when the lights are always turned on and off in the first mode.

[0103] Furthermore, for example, when a specific shooting menu is set in the shooting menu included in the setting information, the CPU 31 may be configured to be able to control the turning on and off of the light irradiation unit 14 in the first mode. Examples of the specific shooting menu are chest shooting and abdominal shooting. With the above configuration, it is possible to prevent the lighting from being turned on unnecessarily, compared to when the lighting is always turned on and off in the first mode.

[0104] Furthermore, for example, the configuration may be such that the shooting method can be set in a shooting menu included in the setting information, and when the shooting method is a specific shooting method, the CPU 31 can control the turning on and off of the light irradiation unit 14 in the first mode. Shooting methods include, for example, standing position shooting without using a bed, and lying position shooting using a bed. For example, the user can set the turning on and off of the light irradiation unit 14 to be controlled in the first mode when shooting in a standing position. With the above configuration, it is possible to prevent the lights from being turned on unnecessarily, compared to when the lights are always turned on and off in the first mode.

[0105] According to this embodiment, it is possible to control the turning on and off of the lights using at least one of a video corresponding to a visible light image and a video of a depth image corresponding to the visible light image.

[0106] In either case, the light irradiating unit 14 is turned off during radiation irradiation.

[0107] 4, 5, and 6 have been described as being executed by the CPU 31 of the console 30, but the processing by the information processing program 100 may be executed by the photographing device 10. When the processing is executed by the photographing device 10, the photographing device 10 is configured to have a control unit capable of executing the information processing program 100.

[0108] In this embodiment, the information processing program 100 is described as being stored in the storage unit 33, but the information processing program 100 may be provided by a storage medium such as a CD-ROM, or may be downloaded via a network.
