Solution Overview
Problem
Existing radiography systems face challenges in performing high-quality long-sized imaging when using different types of radiation detectors, as structures from one detector can appear in the image data of another, degrading image quality.
Innovation Solution
A radiography system that includes a determination unit to assess whether long-sized imaging is possible based on identification and position information of radiation detectors, allowing for appropriate arrangement and correction to prevent structure appearance in image data, thereby maintaining image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple radiation detectors are arranged to perform long-sized imaging, then the observation area is expanded, but structures from detectors closer to the radiation generator appear in image data from detectors farther away, degrading image quality
Solution Approach 1:
The determination unit performs preliminary assessment of detector arrangements and identification information before image acquisition. By determining in advance whether the arranged detectors can perform appropriate long-sized imaging, the system prevents degraded image quality from occurring, rather than attempting correction after the fact.
Solution Approach 2:
The determination unit acts as an intermediary between the detector arrangement configuration and the image acquisition process. It evaluates whether the current arrangement of multiple detectors with different identification information is suitable for long-sized imaging, and provides guidance on appropriate detector placement to avoid structure interference.
2Adaptability or versatility
If different types of radiation detectors are used for long-sized imaging, then detector versatility is improved, but complicated structures from detectors closer to the radiation generator appear in image data from detectors farther away, degrading image quality
Solution Approach 1:
The system assigns different functions to detectors based on their local characteristics and positions. The determination unit evaluates each detector's identification information and arrangement position to determine its suitability for specific imaging tasks, allowing different types of detectors to be used while preventing structure interference through appropriate assignment.
Solution Approach 2:
The determination unit provides feedback on whether the current detector arrangement with different types of detectors is appropriate for long-sized imaging. This feedback mechanism allows the system to adjust detector arrangements or selection to avoid degraded image quality while maintaining the ability to use diverse detector types.
