In this case, since the nurse performs an authentication act on the applicant prior to pre-registration, it is possible to prevent a third party who is not involved in the operation of the patient 16 from performing pre-registration without permission.

  The pre-registration of the portable devices 120a and 120b at the nurse center may be performed, for example, as in the following (1) to (3).

  (1) For example, when the portable device 48 is managed at the nurse center before the operation of the patient 16, an electronic mail is transmitted from the portable devices 120a and 120b to the portable device 48. The mobile device 48 that has received the e-mail transmits a return e-mail attached with a decryption encryption key to the mobile devices 120a and 120b. The portable devices 120a and 120b can acquire the encryption key by receiving a reply e-mail. With the acquisition of the encryption key, pre-registration of the portable devices 120a and 120b with respect to the portable device 48 is completed.

  (2) Unlike the case of (1) above, the mobile device 48 that has received an e-mail from the mobile devices 120a and 120b sends a reply e-mail attached with a two-dimensional barcode corresponding to the encryption key to the mobile device. It transmits to 120a, 120b. When the portable devices 120a and 120b receive the return e-mail, the two-dimensional bar code is displayed on the screen. When the applicant who sees the two-dimensional barcode operates the portable devices 120a and 120b, a decryption encryption key corresponding to the two-dimensional barcode can be acquired.

  (3) Unlike the case of (2) above, the portable device 48 that has received an email from the portable devices 120a and 120b sends a reply email containing a URL (Uniform Resource Locator) according to the encryption key. It transmits to portable device 120a, 120b. When the portable devices 120a and 120b receive the reply e-mail, the contents of the e-mail are displayed on the screen. When the applicant who sees the URL operates the mobile devices 120a and 120b, the decryption encryption key can be acquired from the URL.

  Note that a device connected to a network such as a LAN is assigned a MAC (Media Access Control) address in advance, and the medical institution side pre-registers the person who wants to register in advance (the portable devices 120a and 120b owned by the medical institution). Since there is a possibility of grasping, the MAC addresses of these mobile devices 120a and 120b are registered in advance in the mobile device 48, and the decryption encryption key is stored in the mobile devices 120a and 120b in which the MAC addresses are registered from the mobile device 48. May be delivered.

  In addition, the mobile devices 120 a and 120 b may receive the encryption key from the mobile device 48 instead of performing pre-registration with the mobile device 48. For example, the mobile devices 120a and 120b may receive (download) the encryption key by performing wireless communication or infrared communication with the mobile device 48. Alternatively, the encryption key may be copied to a memory card or a USB memory, and the portable devices 120a and 120b may receive the encryption key from the memory card or the USB memory.

  Further, the encryption key does not always have to be the same (fixed), and may be updated (changed) every time the portable device 48 performs terrestrial digital broadcasting, or one frame image is distributed. It may be updated every time.

  In the following description, it is assumed that the mobile device 120a possessed by another medical staff acquires a public key or a secret key (encryption key) (the mobile device 120a performs pre-registration).

  The image processing unit 144 performs predetermined image processing for displaying a moving image of a camera image, an ultrasonic image, an optical image, and a radiation image on the display unit 160. A moving image after image processing and various kinds of information associated with the moving image are stored in the image memory 146. The image processing unit 144 also performs processing for converting a moving image stored in the image memory 146 into a signal for terrestrial digital television broadcasting.

  The display control unit 148 displays the moving image stored in the image memory 146 and various types of information associated with the moving image on the display unit 160 of the touch panel 150. The operation unit 162 is a widget (an operation image or an end image) such as an icon or a text box displayed on the display unit 160 of the touch panel 150, and is controlled by the doctor 18 operating the operation unit 162. The unit 132 performs various control processes. Further, due to the operation of the operation unit 162 by the doctor 18, the display control unit 148 controls the display unit 160 to display an image according to the operation content.

  As described above, the information management unit 152 manages the contents of the channel and command set by the transmission / reception setting unit 140 and the public key or secret key (encryption key) used for the encryption processing by the encryption processing unit 142 ( Remember.

  The operation control unit 154 is a medical device that performs a predetermined diagnosis or treatment on the patient 16, (1) the radiation output device 22 and the radiation imaging device 24, (2) the ultrasonic diagnostic device 30, and (3) endoscopy. The type of widget displayed on the display unit 160 is limited (limited) so that the doctor 18 can operate any one type of medical device among the mirror devices 32 via the operation unit 162. That is, since many medical devices are arranged narrowly in the operating room 12, in order to smoothly perform an operation on the patient 16, any one medical device is used without simultaneously using a plurality of medical devices. This is because it is preferable to use a device.

  The battery 156 supplies power to each unit in the portable device 48.

  Next, the console 52 will be described. Among the components of the console 52, components having the same names as the components of the portable device 48 have substantially the same function. As described above, since the console 52 and the portable device 48 can be switched to the master or the slave, when the console 52 is the master, it is necessary to exhibit the same function as the portable device 48 described above. Because.

  That is, the communication unit 170 transmits and receives signals by wireless communication with the communication unit 130 of the portable device 48 via the antenna 68. In addition, the communication unit 170 causes the mobile device 48 to function as a repeater via the antenna 68, so that a moving image and various types of information associated with a predetermined area in the medical institution are real-time by digital terrestrial television broadcasting. It is also possible to distribute with. The communication unit 172 transmits and receives signals by wired communication with the control unit 108 of the radiation output device 22, the controller 102, the communication unit 94 of the radiation imaging apparatus 24, and the display device 36.

  The control unit 174 controls each unit in the console 52. The order information storage unit 176 stores order information, and the shooting condition storage unit 178 stores shooting conditions. The switching processing unit 180 switches the console 52 or the portable device 48 to a master or a slave.

  Before the start of fluoroscopic imaging, the transmission / reception setting unit 182 communicates with the communication unit 130 of the portable device 48, the communication unit 130 of the portable device 48, the communication unit 100 of the radiation imaging apparatus 24, the communication unit 170 of the console 52, A channel for performing wireless communication by multiple connection among the ultrasound diagnostic apparatus 30, the endoscope apparatus 32, and the camera 34 is set in advance. In addition, the transmission / reception setting unit 140 selects in advance the contents of commands transmitted from the console 52 to the radiation imaging apparatus 24, the radiation output apparatus 22, the ultrasonic diagnostic apparatus 30, the endoscope apparatus 32, and the camera 34. These setting contents and selection contents are stored (managed) in the information management unit 198.

  When the digital terrestrial television broadcast is performed in real time from the communication unit 170 via the portable device 48 to the predetermined area, the encryption processing unit 184 performs a public key or a secret key on the personal information of the patient 16 described above. Encryption processing is performed using (encryption key). The public key or the secret key is stored in the information management unit 198.

  The image processing unit 186 performs predetermined image processing for displaying a moving image of a camera image, an ultrasonic image, an optical image, and a radiation image on the display unit 192. The moving image after the image processing and various kinds of information associated with the moving image are stored in the image memory 188. In addition, the image processing unit 186 performs processing for converting the moving image stored in the image memory 188 into a signal for terrestrial digital television broadcasting.

  The display control unit 190 causes the display unit 192 to display the moving image stored in the image memory 188 and various types of information associated with the moving image. In this case, the display control unit 190 can cause the display unit 192 to display the same content as the display content displayed on the display unit 160 of the touch panel 150 described above.

  However, the operation unit 194 of the console 52 is a keyboard or a mouse, and the doctor 18 or the engineer 54 operates the keyboard or mouse (operation unit 194) while viewing the display content of the display unit 192. The control unit 174 performs various control processes according to the operation content of the operation unit 194 by the doctor 18 or the technician 54. Further, due to the operation of the operation unit 194 by the doctor 18 or the engineer 54, the display control unit 190 controls the display unit 192 so as to display an image corresponding to the operation content.

  As described above, the information management unit 198 manages the contents of the channel and command set by the transmission / reception setting unit 182 and the public key or secret key (encryption key) used for the encryption processing by the encryption processing unit 184. (Remember.

  The operation control unit 199 is a medical device that performs a predetermined diagnosis or treatment on the patient 16, (1) the radiation output device 22 and the radiation imaging device 24, (2) the ultrasonic diagnostic device 30, and (3) internal vision. The type of widget displayed on the display unit 192 is limited (limited) so that the doctor 18 or the technician 54 can operate any one type of medical device among the mirror devices 32 via the operation unit 194.

  The exposure switch 196 is an exposure button for starting the irradiation of the radiation 20. When the doctor 18 or the technician 54 operates the exposure switch 196, the control unit 174 synchronizes the start of the output of the radiation 20 from the radiation source 106 with the detection of the radiation 20 in the radiation conversion panel 80 and the conversion to the radiation image. As a result, a synchronous control signal for performing fluoroscopic imaging of the imaging region of the patient 16 is generated. Therefore, the console 52 transmits a command corresponding to the synchronization control signal to the control unit 108 and also transmits it to the radiation imaging apparatus 24 via the controller 102.

  FIG. 5 illustrates a state in which the doctor 18 operates the portable device 48 of the tablet PC.

  The portable device 48 is used in a state of being sealed in the sterilization bag 200. In FIG. 5, a moving image 202 (radiation image) of the patient 16 and an icon 204 for the doctor 18 to operate are displayed on the display unit 160 of the touch panel 150.

[Characteristic functions of this embodiment]
The characteristic functions (first to third characteristic functions) of the medical system 10 according to this embodiment configured as described above will be described with reference to FIGS. 6A to 10B.

  The first characteristic function is to change the imaging conditions that occur after the start of fluoroscopic imaging and to perform operations such as positioning of the patient 16 quickly and accurately, after the start of fluoroscopic imaging, The console 52 is switched to each slave.

  The second characteristic function is to allow the portable device 48 at hand to function as a remote controller for each medical device so that the doctor 18 in the operating room 12 can operate various medical devices.

  The third characteristic function is related to the patient 16 in the operating room 12 toward the family of the patient 16 and the medical staff (the portable devices 120a and 120b and the display device 124 possessed by the patient 16) in the predetermined area. A moving image or the like is distributed in real time by terrestrial digital television broadcasting.

  Next, details of the first to third characteristic functions will be described in order.

[First characteristic function]
In the first characteristic function, first, until the fluoroscopic imaging is started, the switching processing unit 180 (see FIG. 4) of the console 52 performs the radiation output device 22 and the radiation imaging device 24 (see FIGS. 1 and 2). The console 52 is maintained at the console 52 and the portable device 48 is maintained as a slave. That is, when an instruction to start fluoroscopic imaging for the patient 16 is received verbally from the operating doctor 18, the technician 54 needs to operate the console 52 to perform operations such as setting imaging conditions. This is because the console 52 needs to be a master until the start.

  As described above, since the signal can be transmitted and received by wireless communication between the portable device 48 and the console 52, the switching processing unit 180 determines the relationship between the master and the slave before the start of fluoroscopic imaging. The switching processing unit 138 (see FIG. 3) of the portable device 48 may be notified from 170 by wireless communication. Accordingly, the portable device 48 can recognize that it is a slave before the start of fluoroscopic imaging, and the control unit 132 prevents the portable device 48 from functioning as a master based on the notification content (by the doctor 18). Each part in the portable device 48 is controlled so that the portable device 48 does not control the radiation output device 22 and the radiation imaging device 24 due to the operation of the touch panel 150.

  Next, after the preparation for fluoroscopic imaging is completed, the control unit 174 generates a synchronization control signal due to the operation of the exposure switch 196 by the technician 54, and the radiation output device 22 and the radiographic imaging via the communication unit 172. When the synchronization control signal (command) is transmitted to the device 24, the switching processing unit 180 determines that the fluoroscopic imaging has started, and switches the console 52 to the slave based on the determination result, and the portable device 48 to the master. Switch.

  Then, the switching processing unit 180 notifies the switching processing unit 138 of the portable device 48 that the master has been switched by wireless communication from the communication unit 170. Accordingly, the mobile device 48 can recognize that the mobile device 48 has been switched to the master after the start of fluoroscopic imaging, and the control unit 132 can function as the master based on the notification content. Each part in the portable device 48 is controlled. As a result, the doctor 18 can control the radiation output apparatus 22 and the radiation imaging apparatus 24 by operating the portable device 48 at hand.

  On the other hand, in the console 52 that has been switched to the slave, the control unit 174 prevents the console 52 from functioning as a master (the console 52 causes the radiation output device 22 and the radiation imaging device 24 to be caused by the operation of the operation unit 194 by the engineer 54). Control each part in the console 52 so as not to control.

  FIG. 6A illustrates the display content of the display unit 160 of the touch panel 150 during fluoroscopic imaging.

  On the screen of the display unit 160, a moving image 210 of the patient 16 is displayed, and two icons 212 and 214 and a personal information display area 216 in which the name and ID of the patient 16 and imaging conditions are displayed are displayed. ing. The icon 212 is an operation icon for temporarily stopping (interrupting) fluoroscopic imaging, and the icon 214 is an operation icon (ending icon) for ending fluoroscopic imaging. The moving image 210 is, for example, a radiographic image obtained by photographing the state of entry of the catheter 222 inserted into the blood vessel 220 of the patient 16, and the catheter 222 progresses in the blood vessel 220 aiming at the stenosis portion 224. .

  The display control unit 148 (see FIG. 3) preferably displays the icons 212 and 214 and the personal information display region 216 so as to avoid the display positions of the blood vessel 220, the catheter 222, and the stenosis portion 224. In addition, the display positions of the icons and the personal information display area are appropriately changed according to the content of the moving image displayed on the screen of the display unit 160 as well in FIGS. 6B to 10B.

  Here, when the fluoroscopic imaging is terminated after a desired image is obtained by fluoroscopic imaging, the doctor 18 may operate the icon 214 (the icon 214 may be touched). Due to the operation of the icon 214 by the doctor 18, the control unit 132 transmits a command instructing the radiography apparatus 24 (see FIGS. 1 and 2) to end fluoroscopic imaging by wireless communication via the communication unit 130. At the same time, the command is transmitted to the radiation output device 22 via the console 52. As a result, the control unit 108 stops the output of the radiation 20 from the radiation source 106 based on the received command.

  Further, when the icon 214 is operated by the doctor 18 or when the command is transmitted, the switching processing unit 138 determines that the fluoroscopic imaging has ended, and determines the portable device 48 based on the determination result. The slave and console 52 are switched to the master. Further, the switching processing unit 138 notifies the switching processing unit 180 (see FIG. 4) of the console 52 by wireless communication from the communication unit 130 that the master has been switched.

  As a result, the console 52 can recognize that it has been switched to the master by the end of fluoroscopic imaging, and the engineer 54 can control the radiation output device 22 and the radiation imaging device 24 by operating the console 52. Become. On the other hand, in the portable device 48 switched to the slave, the control unit 132 controls each part in the portable device 48 so that the portable device 48 does not function as a master.

  By the way, when a radiographic image (for example, an image with low contrast or an image of the patient 16 moving) that is difficult for a doctor to view during fluoroscopic imaging is displayed on the display unit 160, the doctor 18 resets the imaging conditions or the patient 16. In order to perform the positioning, it is determined that the fluoroscopic imaging is temporarily stopped (interrupted), and the icon 212 indicating the pause of the fluoroscopic imaging is operated (touching the icon 212).

  Accordingly, the control unit 132 transmits a command for instructing the temporary stop of the irradiation of the radiation 20 from the communication unit 130 to the radiation imaging apparatus 24 by wireless communication, and transmits the command to the radiation output apparatus 22 via the console 52. Therefore, the control unit 108 interrupts the output of the radiation 20 from the radiation source 106 based on the received command. In addition, the switching processing unit 138 maintains the portable device 48 as a master even when fluoroscopic imaging is interrupted.

  FIG. 6B illustrates the display content of the display unit 160 in a time period when fluoroscopic imaging is interrupted.

  In this case, a moving image 210 is displayed on the screen of the display unit 160, and a personal information display area 216, an icon 226, and a text box display area 228 are displayed. The icon 226 is an operation icon for resuming the fluoroscopic imaging that has been interrupted.

  The text box display area 228 is a widget for changing the shooting conditions for fluoroscopic shooting. That is, in the text box display area 228, a text box for changing the tube voltage and tube current of the radiation source 106 and the irradiation time of the radiation 20, which are imaging conditions, and “OK” for confirming the change contents of the text box. "Button and a" correction "button for correcting or canceling the changed contents.

  Therefore, when the doctor 18 wants to change the imaging condition, the doctor 18 may input a desired condition in each text box and press the “OK” button. The imaging conditions changed by the operation of the doctor 18 are stored in the imaging condition storage unit 136. In addition, the display control unit 148 controls the display unit 160 so that the shooting conditions displayed in the personal information display area 216 are switched to the changed contents. When the technician 54 positions the patient 16, the imaging condition is not changed in the text box display area 228.

  When the doctor 18 operates the icon 226, the control unit 132 transmits a command for restarting the irradiation of the radiation 20 (based on the changed imaging condition) from the communication unit 130 to the radiation imaging apparatus 24 by wireless communication. And transmitted to the radiation output device 22 via the console 52. Accordingly, the control unit 108 restarts the output of the radiation 20 from the radiation source 106 (according to the changed imaging condition) based on the received command.

  In the above description, the case where the master or slave switching process is performed by the switching processing units 138 and 180 of the master device (the portable device 48 or the console 52) has been described. Since it is possible to transmit and receive signals by wireless communication, the switching processing units 138 and 180 of the slave can also perform switching processing.

  6A and 6B is transmitted from the portable device 48 to the console 52 by wireless communication, or the doctor 18 operates the portable device 48 to change the changed imaging conditions from the portable device 48. You may transmit to the console 52 by radio | wireless communication. As a result, the same display content as the display unit 160 of the touch panel 150 is displayed on the display unit 192 of the console 52, and the changed imaging condition is also stored in the imaging condition storage unit 178.

[Second characteristic function]
In the second characteristic function, in order to perform a predetermined diagnosis or treatment on the patient 16, the doctor 18 operates the portable device 48 at hand so that the sterilization level is higher than the surgical instrument used by the doctor 18. This is to control various medical devices of the radiation output device 22 and the radiation imaging device 24, the ultrasound diagnostic device 30, or the endoscope device 32 that are low (the doctor 18 cannot directly operate).

  In this case, first, before each medical device is controlled by the mobile device 48, for example, before the start of fluoroscopic imaging, the transmission / reception setting unit 140 of the mobile device 48 includes the communication unit 130, each medical device, the camera 34, and the console 52. In order to perform wireless communication by multiple access between the devices, a predetermined channel is set for these devices, and the contents of commands transmitted from the portable device 48 to each device are selected in advance. The contents of these channels and commands are managed by the information management unit 152.

  FIGS. 7A to 9B illustrate a case where the doctor 18 (see FIGS. 1 and 5) controls each medical device by operating the touch panel 150 of the portable device 48 in order to perform a predetermined diagnosis or treatment on the patient 16. The display content of the display unit 160 is illustrated. These display contents are displayed on the display unit 160 by the display control unit 148 based on an instruction (notification) from the operation control unit 154 (see FIG. 3).

  First, FIG. 7A illustrates the display contents of the display unit 160 of the touch panel 150 when controlling the radiation output device 22 and the radiation imaging device 24 (see FIGS. 1 and 2) in order to acquire a radiation image of the patient 16. It is a thing.

  On the screen of the display unit 160, a moving image 210, icons 212 and 214, and a personal information display area 216 are displayed, and three icons 230, 232, and 234 are also displayed. The icon 230 is an operation icon for changing imaging conditions for fluoroscopic imaging, the icon 232 is a selection icon for the doctor 18 to select when controlling the ultrasonic diagnostic apparatus 30, and the icon 234 is This is a selection icon for the doctor 18 to select when controlling the endoscope apparatus 32.

  In FIG. 7A, in order to control the radiation output device 22 and the radiation imaging device 24 for the purpose of acquiring a radiation image of the patient 16, the display content related to fluoroscopic imaging is displayed on the screen of the display unit 160. An icon 232 for selecting the ultrasonic diagnostic apparatus 30 and an icon 234 for selecting the endoscope apparatus 32 are displayed in broken lines so that they cannot be selected.

  That is, the operation control unit 154 displays the icon of the icons 212, 214, and 230 that can be operated in FIG. 7A because the content of the diagnosis or treatment currently performed on the patient 16 is acquisition of the radiation image of the patient 16. The display control unit 148 displays the icons 232 and 234 in broken lines on the screen of the display unit 160 according to the notification content.

  In addition, the icons 212, 214, and 230 related to the radiation output device 22 and the radiation imaging device 24 to be controlled (operation objects) are displayed larger than the icons 232 and 234 that cannot be selected.

  This is because a large number of medical devices are arranged in the operating room 12, but when any one of a plurality of medical devices is in use in order to smoothly perform an operation on the patient 16. In order to enable an operation on a medical device in use and invalidate an operation on another medical device that is not in use so that the doctor 18 can reliably operate one medical device to be operated. is there.

  Therefore, in FIG. 7A, when the doctor 18 operates the icon 230, the operation control unit 154 determines that the operation of the icon 230 of the doctor 18 is valid, and notifies the display control unit 148 of the determination result. The display control unit 148 causes the display unit 160 to display the display content of FIG. 6B according to the notification content. Thereby, the doctor 18 can change the imaging condition, and the radiation output device 22 and the radiation imaging device 24 can be controlled from the portable device 48.

  In addition, since it is necessary to interrupt fluoroscopic imaging when changing the imaging conditions, the operation control unit is operated when the icon 230 is operated without operating the icon 212 indicating that fluoroscopic imaging is paused. 154 notifies the control unit 132 of the determination result, and the control unit 132 interrupts the fluoroscopic imaging to the radiation imaging apparatus 24 and the console 52 (via the radiation output apparatus 22 via the communication unit 130) according to the notification content. A command for instructing is sent.

  In FIG. 7A, when the doctor 18 mistakenly operates the icons 232 and 234, the operation control unit 154 determines that the operation content by the doctor 18 is invalid and notifies the display control unit 148 of the determination result. The display control unit 148 continues the screen display of FIG. 7A according to the notification content.

  Further, when the doctor 18 operates the icon 214, the operation control unit 154 determines that the operation of the icon 230 of the doctor 18 is valid and determines that the operation is an instruction to end the fluoroscopic imaging, and the determination results thereof. Is notified to the display control unit 148 and the control unit 132.

  The control unit 132 transmits a command for instructing the end of fluoroscopic imaging to the radiographic imaging device 24 and the console 52 (via the radiation output device 22) via the communication unit 130 in accordance with the notification content, and fluoroscopic imaging. End.

  Moreover, the display control part 148 switches the display content of the display part 160 from FIG. 7A to FIG. 7B according to the said notification content. In FIG. 7B, the display unit 160 displays a moving image 210, a personal information display area 216, and three icons 232 to 236. In this case, the two icons 232 and 234 are switched from the broken line display to the solid line display. The icon 236 is a selection icon for the doctor 18 to select when controlling the radiation output apparatus 22 and the radiation imaging apparatus 24.

  That is, since all the medical devices in the operating room 12 are temporarily not used due to the end of fluoroscopic imaging, icons 232 to 236 corresponding to all the medical devices can be displayed on the display unit 160. Is done. Therefore, if the doctor 18 operates the icon 232, the ultrasound diagnostic apparatus 30 can be controlled, if the icon 234 is operated, the endoscope apparatus 32 can be controlled, and if the icon 236 is operated, the radiation output apparatus 22 and The radiation imaging apparatus 24 can be controlled.

  Specifically, when any one of the three icons 232 to 236 is operated, the operation control unit 154 determines that the operation of the icon is valid, and next determines the medical device corresponding to the icon. The control unit 132 and the display control unit 148 are notified of the determination results. The control unit 132 notifies the medical device that control from the portable device 48 is performed via the communication unit 130 in accordance with the notification content. Moreover, the display control part 148 switches the display content of the display part 160 to the display content according to the said medical device according to the said notification content.

  FIG. 8A illustrates the display contents of the display unit 160 of the touch panel 150 when the ultrasonic diagnostic apparatus 30 is controlled for the purpose of acquiring an ultrasonic image of the patient 16.

  On the screen of the display unit 160, a moving image 240 of ultrasonic images, icons 242, 244, 248 to 252 and a personal information display area 246 are displayed. The moving image 240 includes the organ 254 of the patient 16.

  The icon 242 is an operation icon for temporarily stopping (interrupting) the moving image shooting of the ultrasonic image, and the icon 244 is an operation icon for ending the moving image shooting.

  Furthermore, in description of FIGS. 11-14, it demonstrates, referring FIGS. 1-10B as needed.

[Basic operation of this embodiment]
In step S <b> 1 of FIG. 11, communication settings between devices used in the medical system 10 are performed prior to surgery on the patient 16 (see FIGS. 1 and 2).

  Specifically, the transmission / reception setting unit 140 (see FIG. 3) of the portable device 48 includes a communication unit 130 of the portable device 48, a communication unit 100 of the radiation imaging apparatus 24, a communication unit 170 of the console 52 (see FIG. 4), a camera. 34, the radiography apparatus 24, the ultrasonic diagnostic apparatus 30, the endoscopic apparatus 32, the camera 34, and the console 52 are used to perform wireless communication by multiple connection between the ultrasonic diagnostic apparatus 30 and the endoscopic apparatus 32. Assign a predetermined channel. The transmission / reception setting unit 140 also selects a command to be transmitted to these devices. Further, the transmission / reception setting unit 140 notifies the portable device 120a possessed by another medical staff by a public key or a secret key (encryption key) used for the encryption processing by the encryption processing unit 142. , Pre-registration of the portable device 120a is performed. The allocated channel, the selected command, and the encryption key are managed by the information management unit 152.

  When the patient 16 is guided to the operating room 12 and an operation is performed, the camera 34 starts imaging in the operating room 12 in the next step S2. A moving image (camera image for at least one frame) of the operating room 12 photographed by the camera 34 is sequentially transmitted to the portable device 48 by wireless communication. The image processing unit 144 of the portable device 48 performs processing for converting the received camera image into a signal for terrestrial digital television broadcasting, and stores the processed camera image in the image memory 146.

  In the next step S <b> 3, the control unit 132 starts distributing the camera image stored in the image memory 146 from the communication unit 130 to a predetermined area in real time by digital terrestrial television broadcasting. Thereby, the portable devices 120a and 120b and the display device 124 in the predetermined area receive the camera images and display them on the display units 290a, 290b, and 292, respectively. As a result, other medical personnel and the family of the patient 16 can grasp the current state of the operating room 12 by viewing the display contents of the display units 290a, 290b, and 292. Since the portable device 48 broadcasts only the camera image of the operating room 12 and does not distribute the personal information of the patient 16, only the video of the operating room 12 is displayed on the display units 290a, 290b, and 292.

  The camera image distributed in real time by terrestrial digital television broadcasting is also displayed on the display unit 160 of the portable device 48. Further, the console 52 can also receive a camera image and display the camera image on the display unit 192 or the display device 36.

  Next, after the patient 16 is guided to the operating room 12 and the patient 16 is laid on the operating table 14, the operation of the patient 16 by the doctor 18 is started. As described above, since the camera 34 continues to shoot the operating room 12, the camera image is distributed in real time by digital terrestrial television broadcasting, so that the operation pattern for the patient 16 in the operating room 12 can be changed to the portable devices 120a and 120b. Are displayed on the display units 290a and 290b, the display unit 292 of the display device 124, the display unit 160 of the portable device 48, the display unit 192 of the console 52, and the display device 36, respectively. Thereby, the other medical staff and the family of the patient 16 can grasp that the operation for the patient 16 is being performed.

  During surgery for the patient 16, the doctor 18 instructs the technician 54 to start fluoroscopic imaging verbally when determining that fluoroscopic imaging for the patient 16 is necessary.

  The engineer 54 operates the operation unit 194 of the console 52 in response to an instruction from the doctor 18. Thereby, the control unit 174 acquires the order information from the RIS 112 or the HIS 114, and stores the acquired order information in the order information storage unit 176 (step S4).

  In step S <b> 5, due to the operation of the operation unit 194 by the technician 54, the control unit 174 is based on the imaging region and imaging method of the patient 16 and the information of the radiation output device 22 and the radiation imaging device 24 included in the order information. Then, imaging conditions (tube voltage, tube current, irradiation time) for irradiating the imaging region of the patient 16 from the radiation source 106 of the radiation output device 22 are set, and the set imaging conditions and order information are imaged. Store in the condition storage unit 178.

  In step S <b> 6, the technician 54 positions the imaging region of the patient 16 with respect to the radiation output device 22 and the radiation imaging device 24 after inserting the radiation imaging device 24 between the patient 16 and the operating table 14.

  In this case, the control unit 108 of the radiation output device 22 requests the console 52 to transmit imaging conditions and the like, and the control unit 132 receives the imaging conditions based on the transmission request of the radiation output device 22 received via the communication unit 172. The imaging conditions stored in the storage unit 178 are transmitted to the control unit 108 via the communication unit 172.

  Further, in the radiation imaging apparatus 24, if power is supplied from the battery 92 to the cassette control unit 82 and the communication unit 94, the cassette control unit 82 transmits order information and the like to the console 52 via the communication unit 94. Request. The control unit 132 transmits the order information and the imaging conditions stored in the imaging condition storage unit 178 to the radiation imaging apparatus 24 via the communication unit 172 based on the transmission request of the cassette control unit 82 received via the communication unit 172. To do. The cassette control unit 82 stores the order information and imaging conditions received via the communication unit 94 in the information storage unit 88. In addition, when a voltage is supplied from the battery 92 to each pixel of the radiation conversion panel 80, each pixel reaches a state where the radiation 20 can be converted into charges and stored.

  Further, when power is supplied from the battery 156 of the portable device 48 to each part of the portable device 48, the control unit 132 also requests the console 52 to transmit order information and the like via the communication unit 130. Based on the transmission request of the control unit 132 received via the communication unit 170, the control unit 132 transmits the order information and the shooting conditions stored in the shooting condition storage unit 178 to the portable device 48 via the communication unit 170. The control unit 132 stores the order information received via the communication unit 130 in the order information storage unit 134 and also stores the order information and imaging conditions in the imaging condition storage unit 136.

  The technician 54 turns on the exposure switch 196 on the assumption that preparation for imaging such as positioning of the patient 16 is completed. As a result, the control unit 174 synchronizes the start of the output of the radiation 20 from the radiation source 106 with the detection of the radiation 20 in the radiation conversion panel 80 and the conversion to the radiation image, whereby the imaging part of the patient 16 is detected. A synchronization control signal for executing radiography is generated. The control unit 174 transmits the generated synchronization control signal (command) to the radiation output device 22 via the communication unit 172, and transmits the communication unit 170 to the radiation imaging apparatus 24 and the portable device 48 by wireless communication.

  Thereby, when the control unit 108 of the radiation output device 22 receives the synchronization control signal, the radiation 20 having a predetermined dose is directed from the radiation source 106 toward the imaging region of the patient 16 for a predetermined irradiation time according to the imaging conditions. Irradiate (step S7).

  The radiation 20 passes through the imaging part of the patient 16 and reaches the radiation conversion panel 80 in the radiation imaging apparatus 24. Here, in the case of the direct conversion type radiation conversion panel 80, the radiation 20 is directly converted into electric charges by the radiation conversion layer made of a-Se or the like and accumulated in each pixel. On the other hand, in the case of the indirect conversion type radiation conversion panel 80, the radiation 20 is once converted into fluorescence by the scintillator, and the fluorescence is converted into electric charge and accumulated by the photoelectric conversion element of each pixel.

  Since the cassette control unit 82 receives the synchronization control signal via the communication unit 94, by supplying the control signal to the radiation conversion panel 80, the charge corresponding to the radiation image of the patient 16 accumulated in each pixel. Is read out as an electrical signal. That is, the cassette control unit 82 sequentially reads out the charges of the pixels arranged in a matrix for each line, and temporarily stores an electric signal corresponding to the read charges in the frame memory 84 as a radiation image for one frame (step S8).

  In the next step S9, the association processing unit 90 associates the radiation image for one frame stored in the frame memory 84 with the cassette ID information, order information, and imaging conditions stored in the information storage unit, The radiographic image after linking, cassette ID information, order information, and imaging conditions are stored in the image storage unit 86 (step S10).

  In step S11, the cassette control unit 82 transfers the radiographic image, cassette ID information, order information, and imaging conditions stored in the image storage unit 86 to the controller 102 via the communication unit 94 and the optical fiber cable 58a, and the signal. The data is output to the processing unit 98.

  The signal processing unit 98 performs a predetermined thinning process on the radiographic image to generate a thinned image, and the communication unit 100 wirelessly communicates the thinned image, cassette ID information, order information, and imaging conditions with the portable device 48. Send to.

  When the communication unit 130 of the portable device 48 receives the thinned image and various types of information (cassette ID information, order information, and photographing conditions) associated with the thinned image from the radiation imaging apparatus 24, the control unit 132 displays the thinned image. Then, the associated various information is stored in the image memory 146, and the display control unit 148 causes the display unit 160 to display the thinned image and the associated various information stored in the image memory 146 (step S12). . The doctor 18 can immediately grasp the state of the imaging region of the patient 16 by looking at the display content of the display unit 160.

  On the other hand, the controller 102 stores the radiographic image received via the optical fiber cable 58a and various types of information (cassette ID information, order information, and imaging conditions) associated with the radiographic image in the storage unit 104, The data is transmitted to the console 52 via the fiber cable 58b. When the control unit 174 of the console 52 receives the radiation image and the various types of information associated with each other via the communication unit 172, the control unit 174 stores the image in the image memory 188 and displays the information on the display unit 192 (step S12). The engineer 54 can grasp the state of the imaging region of the patient 16, the image quality of the radiation image, and the like by looking at the display content of the display unit 192.

  In addition, the control unit 174 of the console 52 transfers the radiographic image stored in the image memory 188 and various associated information to the portable device 48 via the communication unit 170 by wireless communication. When the communication unit 130 of the portable device 48 receives the radiation image transferred from the radiation imaging apparatus 24 and various types of associated information, the control unit 132 images the received radiation image and various types of associated information. Once stored in the memory 146. The display control unit 148 controls the display unit 160 so as to display the regular radiation image and various pieces of associated information instead of the thinned image and various pieces of associated information (step S12). The doctor 18 can grasp the detailed situation of the imaging region of the patient 16 and the image quality of the radiation image by looking at the display unit 160.

  Next, the image processing unit 144 converts the radiographic image into a signal for digital terrestrial television broadcasting, while the encryption processing unit 142 uses the encryption key managed by the information management unit 152 to convert the radiographic image into a radiographic image. Encryption processing is performed on various types of linked information. The control unit 132 stores the radiographic image for digital terrestrial television broadcasting and various kinds of encrypted information in the image memory 146, and transmits the radiographic image from the communication unit 130 toward the predetermined area by digital terrestrial television broadcasting. And various encrypted information is distributed in real time. Note that the processing on the receiving side of the portable devices 120a and 120b and the display device 124 will be described in detail with reference to FIG.

  In the next step S13, when fluoroscopic imaging is continued (step S13: NO), the process returns to step S7, and the next radiation 20 is irradiated. Therefore, by repeating the processes in steps S7 to S13, a moving image (radiation images of a plurality of frames) of the imaging region of the patient 16 can be acquired.

  In addition, when the fluoroscopic imaging is ended in step S13 (step S13: YES), the doctor 18 instructs the technician 54 to end the fluoroscopic imaging verbally. When the engineer 54 operates the operation unit 194 in accordance with an instruction from the doctor 18, the control unit 174 transmits a command for instructing the end of fluoroscopic imaging to the radiation output device 22 via the communication unit 172 and also via the communication unit 170. The command is transmitted to the radiation imaging apparatus 24 and the portable device 48 by wireless communication. Thereby, the control unit 108 stops the output of the radiation 20 from the radiation source 106 based on the received command. Thereby, the distribution of the radiation image by the digital terrestrial television broadcast is completed.

  In addition, even if the fluoroscopic imaging is completed, the operation on the patient 16 may be continued. Therefore, the technician 54 does not remove the radiation imaging apparatus 24 inserted between the patient 16 and the operating table 14, The current positioning state of the patient 16 is maintained.

  Thereafter, after the operation on the patient 16 is completed and the patient 16 lying on the operating table 14 leaves the operating room 12, the imaging of the operating room 12 by the camera 34 is stopped (step S14: YES), and digital terrestrial television broadcasting is performed. Distribution of camera images is also terminated.

[Operation by First Characteristic Function]
Next, an operation based on the first characteristic function will be described with reference to FIGS. 12A to 12C.

  In step S20 of FIG. 12A immediately after the fluoroscopic imaging is started in step S7 of FIG. 11, the switching processing unit 180 (see FIG. 4) of the console 52 performs the radiation output device 22 and the radiation imaging device 24 (FIGS. 1 and 2). The master for controlling (see) is switched to the portable device 48, and the console 52 is switched to the slave. Next, the switching processing unit 180 notifies the switching processing unit 138 (see FIG. 3) of the portable device 48 by wireless communication that the relationship between the master and the slave has been switched due to the start of fluoroscopic imaging. Therefore, the control unit 174 controls each part in the console 52 so that the engineer 54 does not operate even if the engineer 54 operates the operation unit 194 or the like (so that the operation by the engineer 54 becomes invalid).

  In the portable device 48, when the communication unit 130 receives the notification content from the switching processing unit 180, it can be recognized that the portable device 48 has been switched to the master by the start of fluoroscopic imaging. Further, the control unit 132 controls each unit of the portable device 48 so that the doctor 18 can operate the portable device 48 based on the notification content. Therefore, after step S20, the medical system 10 performs the processing after step S8 in FIG.

  On the other hand, in step S13, when the doctor 18 operates the icon 214 (see FIGS. 6A and 7A) or a command instructing the end of fluoroscopic imaging due to the operation of the icon 214 is performed by the radiation imaging apparatus 24 and When transmitted to the console 52 (step S13: YES), in step S21 of the next FIG. 12B, the switching processing unit 138 of the master portable device 48 determines that the fluoroscopic imaging has ended, and the determination result is as follows. Based on this, the portable device 48 is switched to the slave and the console 52 is switched to the master. Next, the switching processing unit 138 notifies the switching processing unit 180 of the console 52 by wireless communication from the communication unit 130 that the relationship between the master and the slave has been switched due to the end of fluoroscopic imaging. Therefore, the control unit 132 controls each unit in the portable device 48 so that it does not operate even if the doctor 18 operates the operation unit 162 or the like (so that the operation by the doctor 18 becomes invalid).

  In the console 52, when the communication unit 170 receives the notification content from the switching processing unit 138, it can recognize that the console 52 has been switched to the master by the end of the fluoroscopic imaging. Further, the control unit 174 controls each unit of the console 52 so that the engineer 54 can operate the console 52 based on the notification content.

  Furthermore, when a radiographic image is displayed on the display unit 192 or the like of the portable device 48 in step S12 and this radiographic image is a moving image that is difficult for the doctor 18 to see, the doctor 18 resets the imaging conditions and positions the patient 16. Therefore, it is decided to interrupt the fluoroscopic imaging, and the icon 212 is operated (step S22: YES).

  In this case, the switching processing unit 138 maintains the portable device 48 as a master because the doctor 18 continues to operate the portable device 48 even if fluoroscopic imaging is interrupted (step S23). On the other hand, the control unit 132 of the portable device 48 transmits a command instructing to interrupt the irradiation of the radiation 20 from the communication unit 130 to the radiation imaging apparatus 24 by wireless communication, and also to the radiation output apparatus 22 via the console 52. Send. Therefore, the control unit 108 interrupts the output of the radiation 20 from the radiation source 106 based on the received command.

  Then, in a time period when fluoroscopic imaging is interrupted, the technician 54 positions the patient 16 according to an oral instruction from the doctor 18 (step S6), or the doctor 18 operates the operation unit 162 of the portable device 48. The photographing condition is reset by operating (step S5). Alternatively, when the order information is incorrect, the doctor 18 can also reset the order information by operating the operation unit 162 of the portable device 48 (step S4).

  After these operations, when the doctor 18 operates the icon 226, the control unit 132 sends a command for instructing resumption of irradiation of the radiation 20 (including the imaging conditions after resetting) from the communication unit 130 by wireless communication. Since the data is transmitted to the radiation imaging apparatus 24 and transmitted to the radiation output apparatus 22 via the console 52, the control unit 108 starts from the radiation source 106 (reflecting the imaging conditions after resetting) based on the received command. The output of the radiation 20 can be resumed (step S7).

[Operation by Second Characteristic Function]
Next, the operation by the second characteristic function will be described with reference to FIG.

  First, in step S31, if the doctor 18 (see FIGS. 1 and 5) wants to use a specific medical device, if the other medical device is currently in use (step S31: YES), the doctor 18 The unit 162 (icon 214 in FIGS. 6A and 7A, icon 244 in FIG. 8A, icon 264 in FIG. 9A) is operated to end use of the other medical device (step S32).

  That is, in step S <b> 32, the control unit 132 of the portable device 48 transmits a command for ending moving image capturing to the other medical device through wireless communication via the communication unit 130. As a result, the other medical device ends the shooting of the moving image according to the received command.

  As a result, all medical devices in the operating room 12 can be used, and the display content of the display unit 160 is switched to the display content of FIGS. 7B, 8B, and 9B. 7B illustrates the case where the use of the radiation output apparatus 22 and the radiation imaging apparatus 24 is terminated, FIG. 8B illustrates the case where the use of the ultrasonic diagnostic apparatus 30 is terminated, and FIG. A case where the use of the mirror device 32 is terminated is illustrated.

  In the next step S33, when the doctor 18 operates an icon (any one of the icons 232 to 236, 250, 252, 256, 270, 272, and 282) indicating the specific medical device, operation control is performed. The unit 154 determines that the operation of the icon by the doctor 18 is valid, and notifies the control unit 132 and the display control unit 148 that the specific medical device has been selected. Thereby, the control unit 132 notifies the specific medical device that the specific medical device has been selected as a control target from the communication unit 130 by wireless communication. In addition, the display control unit 148 causes the display unit 160 to display display contents for operating the specific medical device.

  Thereby, in the next step S34, the doctor 18 can operate the specific medical device by operating the operation unit 162. When the doctor 18 operates the operation unit 162 (the icon indicating the specific medical device), the operation control unit 154 determines that the operation of the icon by the doctor 18 is valid, and the operation content is displayed on the control unit 132 and the display. The control unit 148 is notified.

  The control unit 132 transmits a command corresponding to the notification content from the communication unit 130 to the specific medical device by wireless communication. The specific medical device acquires a moving image in accordance with the command, and transmits the acquired moving image to the portable device 48 by wireless communication. Accordingly, the mobile device 48 can display the received moving image on the display unit 160. On the other hand, the display control unit 148 controls the display unit 160 to display the display content corresponding to the notification content.

  In the next step S35, when the use of the specific medical device is ended (step S35: YES), the doctor 18 moves the operation unit 162 (icons 214, 244, 264) in the same manner as in the above-described step S32. The operation of the specific medical device may be terminated by operating (Step S36). Accordingly, the control unit 132 transmits a command for ending the shooting of the moving image to the specific medical device via the communication unit 130 by wireless communication. As a result, the specific medical device ends the shooting of the moving image according to the received command.

  In step S31, when the use of the other medical device is continued (step S31: NO), the processing in step S32 is not performed, and the processing after step S33 is performed on the other medical device. Good. In this case, in the description of steps S33 to S36 described above, if the term “specific medical device” is replaced with “other medical device”, the description is for the other medical device. The description of S33 to S36 is omitted.

[Operation by Third Characteristic Function]
Next, the operation by the third characteristic function will be described with reference to FIG.

  Since the distribution of real-time moving images and various encrypted information (information associated with moving images) by digital terrestrial television broadcasting from the portable device 48 to a predetermined area has already been described in FIG. Here, processing in the mobile devices 120a and 120b and the display device 124 on the receiving side will be described.

  First, in step S41, when the mobile device 120a in the predetermined area receives a moving image and various types of encrypted information, if it is the first reception (step S42: NO), the mobile device 120a receives an encryption key ( For example, a password input screen is displayed on the display unit 290a, and other medical personnel possessing the portable device 120a are preliminarily registered by acquiring the password, etc. (step S43: YES) , Prompt for a password.

  In step S44, the other medical personnel operates the portable device 120a to input the password, and if the input password matches the password acquired in advance, the portable device 120a determines the encrypted information. Decoding processing is performed (step S45), and the moving image and the decoded information are displayed on the display unit 290a (step S46, FIG. 10A). Therefore, other medical personnel can grasp the moving image related to the patient 16 and the personal information (order information, imaging conditions, etc.) related to the patient 16 by looking at the display content of the display unit 290a.

  If the terrestrial digital television broadcast does not end (step S47: NO) and the next moving image and various encrypted information are received (step S41), the portable device 120a is the second or subsequent reception. (Step S42: YES), the password input operation is omitted, and the processing of steps S45 and S46 is performed immediately.

  Therefore, until the terrestrial digital television broadcast is completed (step S47: YES), the portable device 120a repeats the processes of steps S41, S42, and S45 to S47.

  On the other hand, when the mobile device 120b and the display device 124 in the predetermined area receive moving images and various types of encrypted information (step S41), if the first reception (step S42: NO), the mobile device 120b and Since the display device 124 does not perform pre-registration by acquiring a password (step S43: NO), it cannot perform decryption processing on various encrypted information, and displays only moving images on the display units 290b and 292. (Step S48, FIG. 10B). Therefore, the family of the patient 16 can grasp the moving image related to the patient 16 by looking at the display contents of the display units 290b and 292.

  If the terrestrial digital television broadcast is not finished (step S47: NO) and the next moving image and various encrypted information are received (step S41), the portable device 120b and the display device 124 Since it is reception (step S42: YES), the process of step S48 is continued.

  Accordingly, the portable device 120b and the display device 124 repeatedly perform the processes of steps S41, S42, S48, and S47 until the terrestrial digital television broadcast is completed (step S47: YES).

[Effect of this embodiment]
As described above, according to the medical system 10 according to the present embodiment, the following effects can be obtained by having the first to third characteristic functions.

[Effects of the first characteristic function]
According to the first characteristic function, after starting the fluoroscopic imaging, the device (master) that controls the radiation output device 22 and the radiation imaging device 24 is switched from the console 52 to the portable device 48. That is, the portable device 48 and the console 52 are in a master-slave relationship for controlling the radiation output device 22 and the radiation imaging device 24. Before the start of fluoroscopic imaging, the console 52 is the master and the portable device 48 is After the start of fluoroscopic imaging, the console 52 is switched to the slave, and the portable device 48 is switched to the master.

  Thereby, for example, the doctor 18 is disposed in the vicinity of the patient 16 (at the hand of the doctor 18) without instructing the technician 54 to verbally interrupt the fluoroscopic imaging and reset the imaging conditions of the fluoroscopic imaging. By operating the portable device 48 that has been switched to the master, the imaging conditions can be reset quickly and accurately. On the other hand, the technician 54 may perform only the positioning of the patient 16 during the time period in which the fluoroscopic imaging is interrupted in response to the verbal instruction from the doctor 18 when the patient 16 moves. As a result, the work load on the engineer 54 is reduced, and the positioning can be performed quickly.

  Therefore, according to the first characteristic function, it is possible to quickly and accurately perform operations such as change of imaging conditions and positioning of the patient 16 that occur after the start of fluoroscopic imaging. It is possible to resume.

  Further, after the fluoroscopic imaging is completed, the switching processing units 138 and 180 switch the master from the portable device 48 to the console 52, so that the engineer 54 operates the console 52 that has been switched to the master to perform imaging conditions for the next fluoroscopic imaging. Etc. can be set.

  In addition, when the fluoroscopic imaging is interrupted, the switching processing units 138 and 180 maintain the mobile device 48 as a master even if the fluoroscopic imaging is interrupted so that the doctor 18 can operate the mobile device 48. Accordingly, the console 52 is maintained as a slave until the fluoroscopic imaging is completed.

  Furthermore, when the portable device 48 is the master, the radiation output device 22 and the radiation imaging device 24 are controlled due to the operation of the doctor 18 on the touch panel 150 of the portable device 48, and thus the doctor 18 uses the touch panel 150. It is possible to easily reset the shooting conditions by operating. In addition, since the surface of the touch panel 150 is not uneven, if the surface of the touch panel 150 is sterilized after surgery, the surface can be kept clean and hospital infection can be prevented.

  In addition, since the switching processing units 138 and 180 are provided in the portable device 48 and the console 52, and signals can be transmitted and received by wireless communication between the portable device 48 and the console 52, The master / slave switching process can be quickly performed. Further, when the portable device 48 is a master, the portable device 48 can control the radiation output device 22 and the radiation imaging device 24 by causing the console 52 to function as a relay.

  Further, the radiation imaging apparatus 24 transmits and receives signals between the communication unit 94 and the console 52 through wired communication using the optical fiber cable 58, and signals between the communication unit 100 and the portable device 48 through wireless communication. Sending and receiving. In this case, the communication unit 94 transmits a normal radiographic image stored in the image storage unit 86 from the communication unit 94 to the console 52, and the communication unit 100 is generated by thinning out the radiographic image by the signal processing unit 98. The thinned image is transmitted to the portable device 48 by wireless communication.

  A moving image (thinned image) is transmitted from the radiation imaging apparatus 24 to the portable device 48 by wireless communication by generating a thinned image having a smaller data amount than the radiation image (the amount of information is reduced by reducing the frame rate). It becomes possible. As a result, the thinned image can be quickly displayed on the display unit 160 of the portable device 48.

  If a regular radiographic image that is not subjected to thinning processing is transmitted from the radiation imaging apparatus 24 to the console 52 by wired communication, the radiographic image is displayed on the display unit 192 or the display device 36 of the console 52 and stored in the controller 102. The radiographic image can be stored in the unit 104. Further, when the console 52 is a master, the console 52 directly controls the radiation imaging apparatus 24 via the communication unit 94, while when the portable device 48 is a master, the portable device 48 includes a communication unit. It is also possible to directly control the radiation imaging apparatus 24 via 100.

  In addition, even if a radiographic image cannot be stored in the storage unit 104 due to an abnormality in signal transmission / reception between the communication unit 94 and the console 52 via the optical fiber cable 58, the radiation imaging apparatus 24 can be used. By providing the image storage unit 86, a radiation image can be stored on the radiation imaging apparatus 24 side. Furthermore, the radiation imaging apparatus 24 can also transmit a regular radiation image to the console 52 via the portable device 48 by wireless communication. In addition, even if the console 52 is switched to the master, when the abnormal state of signal transmission / reception by the optical fiber cable 58 continues, the console 52 causes the radiographic apparatus 24 to function as the relay device by causing the portable device 48 to function. It can also be controlled.

[Effects of the second characteristic function]
According to the second characteristic function, a signal (command for controlling the medical device) corresponding to the operation content is operated from the communication unit 130 due to the operation of the operation unit 162 of the portable device 48 by the doctor 18. The medical device is transmitted to the target medical device, and the medical device is controlled according to the received signal. Thus, the doctor 18 performing an operation on the patient 16 in the operating room 12 does not give a verbal instruction to an operator of the medical device (for example, an engineer 54) or the surgical instrument used by the doctor 18 Even if it is not possible to directly operate a medical device having a lower sterilization level, the medical device can be controlled by operating the operation unit 162 of the portable device 48 arranged at hand of the doctor 18. Thus, since the portable device 48 functions as a remote controller for each medical device, the doctor 18 controls the desired medical device by operating the portable device 48 at hand according to the progress of the operation. The medical device can be operated quickly and accurately.

  In addition, in the second characteristic function, the operation control unit 154 limits medical devices that are controlled due to the operation of the operation unit 162 by the doctor 18, so that the doctor 18 performs the diagnosis or treatment contents for the patient 16. It is possible to reliably operate an appropriate medical device according to the condition.

  In addition, a large number of medical devices are arranged in the operating room 12, and a plurality of medical devices are not used at the same time in order to smoothly perform an operation on the patient 16. Therefore, when any one of the medical devices is in use, the operation control unit 154 enables the operation of the operation unit 162 by the doctor 18 on the medical device in use and The operation of the operation unit 162 by the doctor 18 with respect to the medical device is invalidated. Accordingly, the doctor 18 can reliably operate one medical device to be operated, and can reliably prevent other medical devices from being erroneously operated.

  The mobile device 48 includes a touch panel 150 including a display unit 160 and an operation unit 162. In this case, the operation unit 162 is an icon that is displayed on the screen of the touch panel 150 and indicates the operation contents of each medical device and / or each medical device, and can be operated by the doctor 18 for each medical device. 204, 212, 214, 226, 230 to 236, 242, 244, 248 to 252, 256, 262, 264, 268, 270, 272, 282, and a text box display area 228. Then, the operation control unit 154 validates the operation of the doctor 18 with respect to the icon or the like corresponding to the medical device in use, and invalidates the operation of the doctor 18 with respect to the icon or the like according to the other medical device.

  As described above, since the operation content for each medical device is displayed as a widget such as an icon or a text box on the display unit 160 of the touch panel 150, the doctor 18 operates the widget to select the medical device in use. Easy to operate. In addition, even if the doctor 18 operates a widget corresponding to another medical device that is not in use, the operation result is invalidated, so that it is possible to reliably prevent other medical devices from being erroneously controlled. it can.

  If the widget corresponding to the medical device being used is displayed larger than the widget corresponding to the other medical device on the display unit 160, the doctor 18 can easily use the widget corresponding to the medical device being used. Can be operated.

  In addition, when the display unit 160 displays end icons 214, 244, and 264 for ending the control of the medical device in use from the portable device 48, and the doctor 18 operates the icons 214, 244, and 264, The operation control unit 154 switches the operation on the icons 232 to 236, 250, 252, 256, 270, 272, and 282 corresponding to each medical device to the valid state. Accordingly, the doctor 18 can select the medical device to be used next by operating the icons 232 to 236, 250, 252, 256, 270, 272, and 282.

  In this case, after the operation of the doctor 18 with respect to each of the icons 232 to 236, 250, 252, 256, 270, 272, and 282 is switched to the valid state, the operation control unit 154 displays an icon corresponding to one medical device. Is operated, it is determined that one medical device corresponding to the operated icon is a new medical device to be used, and a signal corresponding to the determination result is transmitted to the new medical device to be used via the communication unit 130. In addition to the transmission, the operation of the doctor 18 on the operation image corresponding to the other medical device is switched to the invalid state.

  In addition, since many medical devices are arranged in the operating room 12 as described above, it is necessary to reliably transmit a signal (command) from the communication unit 130 to one medical device. Therefore, the portable device 48 sets transmission / reception of signals by multi-access wireless communication between the communication unit 130 and each medical device in advance by the transmission / reception setting unit 140 before controlling each medical device.

  A signal by wireless communication between the communication unit 130 and one medical device within a limited frequency band (for example, a band of 2.4 GHz to 2.56 GHz) by setting transmission / reception of a signal by multiple access in advance. Can be reliably transmitted and received.

  Further, when the radiation output device 22 and the radiation imaging device 24 are in use, the portable device 48 transmits a signal corresponding to the operation content operated by the operation unit 162 from the communication unit 130 to the console 52 by wireless communication. As a result, the radiation output device 22 and the radiation imaging device 24 are controlled via the console 52. Accordingly, the portable device 48 can control the radiation output device 22 and the radiation imaging device 24 by causing the console 52 to function as a relay.

  Alternatively, the radiation output device 22 and the radiation imaging device 24 are controlled by transmitting a signal from the communication unit 130 to the radiation imaging apparatus 24 and transmitting a signal from the communication unit 130 to the radiation output device 22 via the console 52. May be. Even in this case, the portable device 48 can directly control the radiation imaging apparatus 24 and can control the radiation output apparatus 22 by causing the console 52 to function as a relay.

[Effects of the third characteristic function]
According to the third characteristic function, a moving image related to diagnosis or treatment of the patient 16 is directed to a predetermined area in real time by digital terrestrial television broadcasting (in the case of Japan, area one segment broadcasting). Can be delivered.

  Thus, when the doctor 18 is performing an operation on the patient 16 in the operating room 12, the camera 34 captures a moving image (camera image) of the operating room 12, and the radiographic apparatus 24, ultrasonic diagnosis. The device 30 and the endoscope device 32 capture a moving image (a radiographic image, an ultrasonic image, or an optical image related to diagnosis or treatment of the patient 16) inside the patient 16. Then, the communication unit 130 of the portable device 48 possesses these moving images by the family of the patient 16 who is waiting in a predetermined area such as a waiting room in a medical institution, and has a reception function of terrestrial digital television broadcasting. Possessed by a portable device 120b such as a mobile phone, or other medical personnel (doctors, residents, medical students) in a predetermined area such as the operating room 12, the preparation room 50, or a conference room in the medical institution, and It can be distributed to a mobile device 120a such as a mobile phone having a reception function of terrestrial digital television broadcasting, or a display device 124 such as a display installed in the predetermined area.

  As a result, the moving image can be relayed live to the family of the patient 16 and other medical personnel, and it is clear whether or not the operation on the patient 16 is appropriately performed. If the family of the patient 16 and another medical person are in the same room, the family of the patient 16 is watching the moving image displayed on the display unit 290b of the portable device 120b or the display unit 292 of the display device 124. It is also possible to receive an explanation from other medical personnel as appropriate regarding the progress of the operation on the patient 16. Furthermore, other medical personnel can give appropriate advice to the doctor 18.

  As described above, according to the third characteristic function, the diagnosis or treatment status of the patient 16 in the operating room 12 is directed to the family of the patient 16 and other medical personnel in the predetermined area in real time. It becomes possible to broadcast on.

  Further, the communication unit 130 of the portable device 48 directly receives a radiographic image from the radiation imaging apparatus 24 through wireless communication, or receives a radiographic image from the radiation imaging apparatus 24 through wireless communication via the optical fiber cable 58 and the console 52. Receive. In either case, the portable device 48 functions as a repeater for terrestrial digital television broadcasting.

  Further, when the communication unit 130 broadcasts a moving image and various encrypted information in a predetermined area in real time, the mobile device 120a in the predetermined area performs decryption on the various encrypted information. Thus, the moving image and the information can be browsed, while the mobile device 120b and the display device 124 can browse only the moving image. As a result, only the other medical personnel can view the moving image and the various encrypted information that is personal information, while the family of the patient 16 can view only the moving image. As a result, it is possible to prevent a third party from browsing personal information using a mobile phone.

  Furthermore, since the portable device 48 that performs digital terrestrial television broadcasting is disposed on the mounting table 46 slightly away from the patient 16, it is possible to suppress the influence of radio waves from the digital terrestrial television broadcasting on the patient 16. At the same time, it is possible to avoid the influence of the radio wave condition of the digital terrestrial television broadcast due to the presence of the patient 16.

  In addition, since digital terrestrial television broadcasting is performed from the portable device 48 instead of various medical devices in the operating room 12, the portable radiation imaging device 24, the ultrasonic diagnostic device 30, the endoscope device 32, and these medical devices It is also possible to suppress the influence of radio waves of the terrestrial digital television broadcast on the battery mounted on the device.

[Effects common to the first to third characteristic functions]
In the first to third characteristic functions, since the portable device 48 is a tablet PC, a handheld computer, or a PDA, the portable device 48 can be easily carried to the vicinity of the patient 16.

  In particular, tablet computers do not have a keyboard or mouse and have no irregularities on the surface, so if the surface of the tablet computer is sterilized after surgery, the surface can be cleaned and hospital infections can be prevented. Is also possible.

  In addition, the portable device 48 is used in a state of being sealed in the sterilization bag 200, and the doctor 18 operates the portable device 48 through the sterilization bag 200, so that the portable device 48 is kept clean. Can do. If the sterilization bag 200 is a disposable transparent bag, the portable device 48 can be sealed in a new sterilization bag 200 and repeatedly used without sterilizing the portable device 48.

  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.
