Radiation Image Capture Device Selective Panel Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radiation image capture systems, the time taken for image display on external devices is prolonged when all images from multiple radiation detection panels are transmitted, and there is a risk of image recapture if the wrong panel is used for image capture, leading to inefficiencies in workflow and potential loss of captured images.
Innovation Solution
A radiation image capture device with multiple detection panels that designates and transmits only the display target image, using a controller to store and display other images, ensuring efficient data transmission and avoiding unnecessary image recapture by determining the presence of the imaging subject on each panel through irradiation detection pixels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all images from multiple radiation detection panels are transmitted to external devices, then complete image data is available for display, but the transmission time and waiting time for image display are prolonged
Solution Approach 1:
The patent extracts and transmits only the necessary image data (display target image) from multiple radiation detection panels rather than transmitting all images. The controller identifies which panel contains the imaging subject and selectively transmits only that panel's image data to the external device, thereby reducing transmission time while maintaining data completeness for display purposes.
Solution Approach 2:
The patent segments the image data from multiple panels by identifying and separating the display target image from other images. The controller divides the overall image data set into relevant (display target) and irrelevant (other panels) segments, transmitting only the relevant segment to external devices, thus optimizing transmission efficiency.
2Reliability
If images from all panels are transmitted and displayed, then no image recapture is needed, but workflow efficiency decreases due to prolonged display time
Solution Approach 1:
The patent employs feedback mechanisms where irradiation detection pixels provide information about which panel actually detected the imaging subject. This feedback allows the controller to make informed decisions about which images to transmit and display, ensuring accuracy while optimizing workflow by avoiding unnecessary transmission and display of irrelevant images.
Solution Approach 2:
The patent performs preliminary identification of the display target image using irradiation detection pixels before transmission. By determining in advance which panel contains the imaging subject, the system prepares the correct image data for transmission, preventing the need for recapture and improving workflow efficiency.
3Loss of time
If only the display target image is transmitted, then transmission time is reduced, but there is a risk of using the wrong panel for image capture
Solution Approach 1:
The patent introduces irradiation detection pixels as intermediaries between the radiation detection panels and the controller. These pixels detect whether radiation has actually struck each panel and provide this information to the controller, which uses it to accurately identify the display target image. This intermediary mechanism ensures reliable selection of the correct panel while maintaining fast transmission.

AI summary
A radiation image capture device includes plural radiation detection panels that each detect incident radiation that has passed through an imaging subject, that each generate a radiation image, and that are disposed in a row in a direction orthogonal to the radiation incident direction. The radiation image capture device designates a display target image from out of plural radiation images respectively generated by the plural radiation detection panels, and transmits the designated display target image to a console. At least a radiation image other than the display target image is stored in an image memory. The console displays on a display section the received display target image and, in response to data indicating a display request for a radiation image other than the display target image, also displays on the display section the radiation image other than the display target image read from the image memory.
