Radiation Imaging Retainers Positioning Outside Pixel Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiation imaging systems for long-length photographing in medical diagnostics often suffer from artifacts due to the lack of a retainer configuration that retains the position of radiation imaging devices, leading to image quality degradation.
Innovation Solution
A radiation imaging system with a housing containing multiple radiation imaging devices and retainers that position and retain the devices in areas outside their effective pixel areas, preventing spatial overlap and thus reducing artifacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If retainers are used to position and retain radiation imaging devices, then device positioning stability is improved, but artifacts may occur in the obtained image
Solution Approach 1:
The harmful retainer structures are extracted and removed from the effective pixel areas. The patent specifically designs retainers that are positioned only in non-effective areas, thereby separating the positioning function from the imaging area to eliminate artifacts while maintaining positioning stability
Solution Approach 2:
The retainer configuration is optimized with different properties in different locations. Retainers are provided only in non-effective areas adjacent to effective pixel areas, while no retainers are placed within effective pixel areas. This local differentiation ensures positioning stability where needed while preventing artifacts in imaging regions
2Adaptability or versatility
If multiple radiation imaging devices are arranged to perform long-length photographing, then photographing capability is improved, but device complexity increases
Solution Approach 1:
Multiple radiation imaging devices are merged into a single housing structure with integrated retainer mechanisms. The housing contains multiple devices arranged in specific configurations, and retainers are integrated into the housing to position multiple devices simultaneously, reducing overall system complexity while maintaining long-length photographing capability
Solution Approach 2:
The housing structure serves multiple functions: it contains multiple radiation imaging devices, provides integrated retainer mechanisms for positioning, and enables long-length photographing capability. The retainers are designed to universally position devices in both effective and non-effective areas, making the system multi-functional and reducing overall complexity
