Radiographic Controller Stops Processing for Preview Rejection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radiographic systems, immediate image re-capturing is hindered and battery power is wasted due to unnecessary processing when image re-capturing is needed, causing inconvenience and reduced efficiency.
Innovation Solution
A radiographic system with a controller that stops processing upon receiving a stop signal from the console, allowing for immediate image re-capturing and preventing unnecessary battery usage by restoring functional sections to pre-image capturing conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the radiographic apparatus automatically completes the full processing sequence (transmission of remaining image data, reset processing, read-out of offset data) after image capturing, then the system maintains automated operation and ensures complete data processing, but the radiological technologist cannot perform immediate image re-capturing and unnecessary processing consumes battery power
Solution Approach 1:
The system transmits thinned-out data to the console before completing the full processing sequence, enabling the console to display a preview image in advance. This preliminary action allows the radiological technologist to evaluate whether re-capturing is necessary before the apparatus completes reset processing and offset data read-out, thereby enabling immediate re-capturing when needed without waiting for the full automated sequence to finish.
2Reliability
If the radiographic apparatus completes all processing steps including reset processing and offset data read-out after image capturing, then complete image processing is ensured, but battery power is wasted on unnecessary processing when re-capturing is needed
Solution Approach 1:
The system performs preliminary transmission of thinned-out data to the console for preview display before completing the full processing sequence. This allows the radiological technologist to determine in advance whether re-capturing is necessary, enabling the system to skip unnecessary reset processing and offset data read-out steps when re-capturing is required, thereby conserving battery power while maintaining processing reliability when needed.
Solution Approach 2:
The console displays a preview image based on thinned-out data transmitted from the radiographic apparatus. The radiological technologist provides feedback by determining whether re-capturing is necessary based on this preview. This feedback mechanism enables the system to adjust its processing behavior, avoiding unnecessary energy-consuming operations when the preview indicates re-capturing will be needed.
3Ease of operation
If the system transmits thinned-out data for preview display before completing full processing, then immediate re-capturing becomes possible, but the processing sequence must be interruptible and controllable
Solution Approach 1:
The system transmits thinned-out data to the console in advance and displays a preview image, enabling the radiological technologist to evaluate the need for re-capturing before the apparatus completes its processing sequence. This preliminary data transmission and display mechanism provides operational flexibility without requiring complex real-time interruption capabilities, as the data transmission occurs before the full processing sequence completes.

AI summary
A radiographic system includes: a radiographic apparatus; a radiation generator that irradiates radiation to the radiographic apparatus; and a console which forms a radiation image based on an image data transmitted from the radiographic apparatus, wherein when a radiation image capturing is completed, a controller transmits thinned-out data in which read-out image data are thinned at a prescribed ratio, to the console, which displays a preview image on a display section based on the thinned-out data, when a rejection operation that rejects the preview image through an input section is conducted, the console transmits a stop signal that instructs the radiographic apparatus to stop a series of processing, and wherein when the controller receives the stop signal, the controller stops the series of processing currently in progress, and returns an operation state of each functional section to an operation state before the radiation image capturing is carried out.
