Radiation image capturing systems face challenges in reliably identifying and preventing the misuse of radiation conversion panels and patients, leading to potential errors in image capture and patient treatment.
Innovation Solution
A method and system that include a conversion panel identification information reading unit to read and verify the identification information stored on the conversion panel, and an identifying unit to check and match this information against specified data, ensuring proper panel and patient identification before image capture, with features like wireless communication and automatic inhibition of radiation application if mismatches are detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If radiation conversion panels are made separate and portable for capturing images of various patient areas, then ease of operation is improved, but reliability deteriorates due to potential mixing up or mistaken use of panels
Solution Approach 1:
The system implements automatic feedback by reading identification information from the radiation conversion panel and comparing it with the specified patient and examination information. The system provides immediate feedback when mismatches are detected, preventing erroneous image capture and ensuring reliable panel identification throughout the imaging process
Solution Approach 2:
An identification information reading device acts as an intermediary between the radiation conversion panel and the control system. This intermediary automatically reads and verifies panel identification information, eliminating manual verification errors while maintaining the portability and ease of use of the panels
2Device complexity
If manual verification of panel and patient information is used, then device complexity is reduced, but reliability deteriorates due to human error in identification
Solution Approach 1:
The radiation conversion panel performs self-identification by automatically providing its identification information to the reading device. This self-service mechanism eliminates the need for manual verification while maintaining system simplicity, as the panel autonomously presents its identity for verification against the examination requirements
Solution Approach 2:
The manual mechanical verification process is replaced with an automated optical or electromagnetic reading system. The identification information reading device automatically captures and verifies panel identification data, substituting human visual inspection and manual comparison with an automated electronic verification system that eliminates human error while keeping the interface simple
3Reliability
If identification verification system is implemented, then reliability is improved, but device complexity increases due to additional reading and verification components
Solution Approach 1:
The identification information reading device is designed with multi-functionality, serving both to read panel identification information and to verify it against patient and examination data. This universal device performs multiple functions (reading, comparing, verifying, and controlling) within a single integrated component, minimizing the number of separate parts needed while maintaining high reliability
Solution Approach 2:
The verification functions are merged into the existing control system of the radiation imaging apparatus. The identification reading, comparison, and verification processes are combined with the overall system control, eliminating the need for separate standalone verification devices and reducing overall system complexity while enhancing reliability
4Reliability
If automatic inhibition of radiation application is implemented upon mismatch detection, then reliability is improved, but productivity decreases due to interruption of image capture process
Solution Approach 1:
The identification verification is performed as a preliminary action before radiation application. By checking panel and patient information matches in advance and only permitting radiation application when verification succeeds, the system prevents erroneous radiation use without requiring interruptions during the actual imaging process, thus maintaining productivity while ensuring safety

AI summary
A radiation image capturing method, a radiation image capturing system, and a radiation information system are provided. In the present invention, a console checks a cassette ID (specified cassette ID) sent from an RIS server as the cassette ID of a radiation detecting cassette that is planned to be used to capture a radiation image, and a cassette ID (actual cassette ID) that is read by the console from a radiation detecting cassette which is placed in an operating room or an image capturing room and which is to be actually used to capture a radiation image, with each other. Based on the result of the cassette ID check, the console determines whether to permit a radiation image to be captured or not.
