Description

  The present invention relates to a radiation imaging system that performs imaging using radiation on a patient according to the contents of an examination, a control method thereof, and a program for causing a computer to execute the control method.

  2. Description of the Related Art Conventionally, a radiation imaging apparatus is known that irradiates an object subject with radiation (for example, X-rays), detects an intensity distribution of the radiation transmitted through the object, and captures a radiation image of the object. Such devices are mainly used in the medical field, the industrial field, and the like. In recent years, a technique of converting radiation transmitted through a subject into an electrical signal and acquiring a radiation image as digital data has been widely adopted.

  For example, in the medical field, examinations using radiation are routinely performed. In an examination using radiation (radiation examination), an examination request document in which an imaging region and an imaging method are described is generally created by a doctor in each clinical department. Then, the radiographer performs a radiation inspection according to the inspection request form. Some hospitals have hospital networks that connect various medical devices. When such a network environment is constructed, the radiation imaging system performs imaging in cooperation with a hospital information system (HIS), a radiation information system (RIS), an image server (PACS), and the like.

  In a hospital where a hospital network is constructed, an inspection request is issued from the HIS instead of issuing an inspection request form. In this case, the radiology department receives an inspection request from the HIS in the RIS, and performs a radiological inspection corresponding to the inspection request in the radiation imaging system.

  When the radiation inspection is completed, the radiation imaging system notifies the HIS and RIS that the inspection is completed, and outputs the captured image and the inspection information to the PACS, the printer, and the like. In addition, the captured image and the inspection information may be displayed on the display device.

  In relation to this, in Patent Document 1 below, in order to prevent leakage of personal information, a subject who is a subject enters and exits the photographing room and recognizes the photographed image and the examination information from a display which is a display device. A method of erasing has been proposed.

JP 2007-117632 A

  Personal information of many patients such as a list of examination information issued from RIS and HIS and a list of completed examinations are displayed on the radiation imaging system.

  In operation using the fluoroscopic imaging system, a patient may be operated while a display is installed in the imaging room and a fluoroscopic image is confirmed in the imaging room. For this reason, there is a possibility that personal information of many patients displayed on the display in the radiographing room will enter the eyes of the patient who entered the radiographing room.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a mechanism for protecting personal information of a patient handled by a radiographic system.

The radiation imaging system of the present invention is a radiation imaging system that performs imaging using radiation on a patient in accordance with the contents of an examination, and a plurality of displays for displaying images related to examination information including personal information of the patient Means, extraction means for extracting personal information of the patient from the examination information displayed as the video, and personal information other than the patient performing the examination is included in the personal information of the patient extracted by the extraction means Determination means for determining whether or not there is, and output control means for controlling a video output method of the video for the plurality of display means based on a determination result by the determination means.

For example, a captured image and patient information associated with the captured image are acquired from the ROM, the PACS 13 or the storage unit 55 (captured image storage unit 551) in the device itself. The captured image is stored in the ROM, the PACS 13 or the storage unit 55 (captured image storage unit 551) in association with the patient information of the captured image. Further, the acquisition unit 51 acquires inspection information based on the inspection request from the RIS 12, for example, from a ROM or the like.

  The instruction detection unit 52 detects a display switching instruction for the currently displayed screen based on an input operation by the operator. Specifically, when the operator operates the patient information confirmation button 102 using a mouse or the like while the examination input screen shown in FIG. 2 is displayed, the instruction detection unit 52 detects the operation and detects the patient. The display control unit 54 and the determination unit 57 are notified that the information has been confirmed.

  The imaging control unit 56 controls imaging of a patient's radiographic image using, for example, a radiation detection apparatus according to the instructed imaging method. The imaging control unit 56 controls imaging of a patient's radiographic image using, for example, imaging conditions related to the instructed imaging method. In addition, in the image display area 110 in FIG. 3, for example, a radiographic image that has been subjected to image processing using an image processing condition related to the designated imaging method is displayed.

  The extraction unit 53 extracts the patient's personal information included in the video output from the display control unit 54. In the present embodiment, for example, the patient personal information is information for identifying a patient such as a patient ID, a patient name, and a date of birth.

  FIG. 6 is a schematic diagram showing an example of the configuration of an element information table used in the case where the extraction unit 53 shown in FIG. 5 extracts patient personal information according to the first embodiment of the present invention. Specifically, in the element information table shown in FIG. 6, items of screen ID, screen name, element ID, and element name are defined.

  The extraction unit 53 receives a notification of the updated screen ID from the display control unit 54 when the display is updated due to screen transition or the like. Then, the extraction unit 53 extracts the patient personal information displayed by the element included in the notified screen ID, and notifies the determination unit 57 of the extraction result.

  The determination unit 57 determines whether or not the personal information of the patient extracted by the extraction unit 53 includes personal information other than the patient (that is, personal information other than the patient to be examined). Specifically, the determination unit 57 compares the patient information notified by the instruction detection unit 52 with the patient personal information notified by the extraction unit 53, and the patient personal information different from the patient information is extracted. In this case, the display control unit 54 is notified that personal information other than the patient is displayed.

  The display control unit 54 generates a display screen (display image) based on the examination information, the captured image, and the like acquired by the acquisition unit 51. In addition, the display control unit 54 includes an output control unit (not shown) that controls the video output method of the video to the plurality of photographing device display units 2a and 2b based on the determination result by the determination unit 57. .

Here, in this embodiment, among the plurality of imaging device display units 2a and 2b, the imaging device display unit 2a arranged in the operation room where the patient does not enter is set in advance as a main display unit. And On the other hand, when receiving a non-display notification of personal information other than the patient information from the determination unit 57, the output control unit starts video output to all the imaging device display units 2a and 2b.

Here, with reference to FIG. 7, the flow of the video output control process when performing the inspection in the X-ray imaging system shown in FIG. 1 will be described.
FIG. 7 is a flowchart showing an example of a processing procedure of a control method in the radiation imaging system (X-ray imaging system) according to the first embodiment of the present invention. A display update process corresponding to patient information to be performed (examination object) will be described.

  First, in step S201, the imaging device control unit 5 determines whether or not patient information to be examined is confirmed. If the patient information is confirmed as a result of this determination (S201 / YES), the process proceeds to step S202.

  In step S202, the imaging device control unit 5 extracts the personal information to be displayed from the personal information display element of the screen to be displayed. For example, the extraction unit 53 specifies the personal information display element from the element information table shown in FIG. 6 using the screen ID notified from the display control unit 54 at the time of display update, and is indicated in these elements. The personal information is extracted and notified to the determination unit 57.

  Subsequently, in step S203, the determination unit 57 determines whether or not the personal information notified from the extraction unit 53 includes personal information other than the patient (that is, personal information other than the patient to be examined). (to decide. As a result of this determination (judgment), if personal information other than the patient is included in the notified personal information (S203 / YES), the process proceeds to step S204.

  For example, when the performed inspection button 115 is pressed on the photographing screen illustrated in FIG. 3 and the display update for displaying the performed inspection selection screen illustrated in FIG. 4A is processed, the determination unit 57 performs the performed inspection list 123. It is determined that the personal information other than the patient is included in.

  In step S204, the display control unit 54 (output control unit) receives a personal information display notification other than the patient from the determination unit 57, and stops video output to the imaging device display unit 2 other than the main display unit. . Here, in this embodiment, since the imaging device display unit 2a arranged in the operation room is set as the main display unit, in step S204, the imaging device display unit 2b arranged in the imaging room is displayed. Video output will be stopped. That is, the video output method in step S204 is a mode (single mode) in which video is output only to the photographing device display unit 2a arranged in the operation room as the main display unit. Further, in the present embodiment, for example, before stopping the video output to the photographing device display unit 2b installed in the photographing room, the operator is notified that the video output is stopped, and further, the operator outputs the video. You may make it select whether to stop.

  On the other hand, as a result of the determination (judgment) in step S203, if personal information other than the patient is not included in the notified personal information (S203 / NO), the process proceeds to step S205.

  For example, when the new examination button 114 is pressed on the performed examination selection screen illustrated in FIG. 4A and the display update for displaying the imaging screen illustrated in FIG. 3 is processed again, the determination unit 57 may select an individual other than the patient. It is determined that no information is included.

  In step S205, the display control unit 54 (output control unit) receives notification of non-display of personal information other than the patient from the determination unit 57, and starts video output to all the imaging device display units 2a and 2b. The video output method in step S205 is a mode (mirror mode) in which the same video is output to all the photographing device display units 2a and 2b.

  If the patient information is not confirmed as a result of the determination in step S201 (S201 / NO), the process proceeds to step S204, and video output to the imaging device display unit 2 (2b) other than the main display unit is stopped. To do.

  Then, when the output control process in step S204 or step S205 ends, the process of the flowchart in FIG. 7 ends.

  In the present embodiment, for example, when the video output method is initially in the mirror mode and then switched to the single mode, the operator is notified of this, and further, the operator is switched to the single mode. You may make it select whether to switch.

  As described above, according to the first embodiment described above, by setting the imaging device display unit 2a of the operation room as the main display unit in advance, an image including personal information other than the patient to be examined can be displayed. The image is not output to the photographing device display unit 2b of the photographing room to enter. In addition, by setting the screen for performing imaging of the patient to a screen configuration that does not include personal information other than the patient, information regarding imaging can be output to the imaging device display unit 2b in the imaging room.

(Second Embodiment)
Next, a second embodiment of the present invention will be described.
In 1st Embodiment, the case where the video output to imaging | photography apparatus display parts 2 (2b) other than the main display part was stopped based on the personal information display determination result was demonstrated. In the second embodiment, a case will be described in which the display color of personal information other than the patient to be examined and the background color have the same luminance (same brightness) color scheme.

  The schematic configuration of the radiation imaging system (X-ray imaging system) according to the second embodiment is the same as the schematic configuration of the radiation imaging system (X-ray imaging system) according to the first embodiment shown in FIG. The functional configuration of the imaging device control unit 5 according to the second embodiment is the same as the functional configuration of the imaging device control unit 5 according to the second embodiment shown in FIG.

  In the second embodiment, the imaging device display unit 2a in the operation room shown in FIG. 1 is a display that outputs a color image, and the imaging device display unit 2b in the imaging room shown in FIG. 1 is a display that outputs a monochrome image. .

  When receiving a personal information display notification other than the patient from the determination unit 57, the display control unit 54 sets the personal information display color in the personal information display element included in the element information table and the background color of the personal information display element to the same luminance. The color is set to (same brightness), and the video is output to all the photographing device display units 2a and 2b.

  The photographing device display unit 2b in the photographing room that outputs monochrome video is not affected by the difference in hue and saturation, and the personal information display color in the personal information display element and the background color of the personal information display element are output as the same color. Therefore, an image that cannot read personal information is output. On the other hand, in the photographing device display unit 2a in the operation room that outputs a color image, an image from which personal information can be read is output depending on the difference in hue and saturation.

  Here, before the video of the imaging device display unit 2b installed in the imaging room becomes a video in which personal information cannot be read, the operator is notified that the color scheme will be changed, and further, the operator is asked whether or not to change the color scheme You may make it make it.

  On the other hand, when receiving a non-display of personal information other than the patient from the determination unit 57, the display control unit 54 displays the personal information display color in the personal information display element included in the element information table and the background color of the personal information display element. Is a color scheme of different luminance (unevenness), and video is output to all the photographing device display units 2a and 2b. In this case, an image from which personal information can be read is output regardless of a color output image or a monochrome output image.

Here, with reference to FIG. 8, the flow of the video output control process when the inspection is performed in the X-ray imaging system shown in FIG. 1 will be described.
FIG. 8 is a flowchart illustrating an example of a processing procedure of a control method in the radiation imaging system (X-ray imaging system) according to the second embodiment of the present invention. In FIG. 8, the same processing steps as the processing steps shown in FIG. 7 are given the same step numbers, and detailed description of the processing will be omitted.

  First, in the process according to the second embodiment, the process of steps S201 to S203 shown in FIG. 7 is performed.

  When it is determined in step S201 that patient information has not been confirmed (S201 / NO), or when personal information other than the patient is included in the personal information notified in step S203 (S203). / YES), the process proceeds to step S211.

  In step S211, the display control unit 54 (output control unit) receives a personal information display notification other than the patient from the determination unit 57, and displays the display color of the personal information display element other than the patient and the personal information display element. The video is output to all the photographing device display units 2a and 2b with the background color as the color scheme having the same luminance (same brightness). The video output method in step S211 is a mode for outputting a video in which the display color of the patient's personal information and the background color of the personal information have the same luminance color scheme (same luminance color scheme mode).

  On the other hand, when personal information other than the patient is not included in the personal information notified in step S203 (S203 / NO), the process proceeds to step S212.

  In step S212, the display control unit 54 (output control unit) receives a personal information non-display notification other than the patient from the determination unit 57, and displays the display color of the personal information display element of the patient and the personal information display element. A video is output to all of the photographing device display units 2a and 2b with the background color as a color scheme of different luminance (unevenness). The video output method in step S212 is a mode (different luminance scheme) that outputs an image in which the display color of the patient's personal information and the background color of the personal information have different luminance schemes.

  Then, when the output control process of step S211 or step S212 is completed, the process of the flowchart of FIG. 8 is terminated.

  In the present embodiment, for example, when the video output method is initially the different luminance color combination mode, and then switches to the same luminance color arrangement mode, the operator is notified of this, and further, the operator May select whether to switch to the same luminance coloration mode.

  As described above, according to the second embodiment described above, the display color of the personal information other than the patient to be examined and the background color are set to have the same luminance (same brightness) color scheme, so that the imaging room that outputs a monochrome video is displayed. In the imaging device display unit 2b, an image in which personal information other than the patient cannot be read is output. On the other hand, in the imaging device display unit 2a of the operation room that outputs a color image, an image that can read all personal information is output.
