Scintillator Support Structure for Radiation Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radiation imaging apparatuses with a stacked structure of a sensor panel and a scintillator, deformation nonuniformity at the joints between imaging substrates leads to nonuniform distortion of the scintillator, causing artifacts in the images sensed, and increasing the thickness of the base to reduce distortion results in increased weight and limited effectiveness.
Innovation Solution
A radiation imaging apparatus with a housing that includes support members between the scintillator and the housing's plate-shaped portions to support the scintillator, with the second support member specifically configured to support the peripheral portion of the scintillator outside the imaging area, reducing distortion by enhancing mechanical strength at the substrate joints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the base thickness is increased to reduce scintillator distortion, then the distortion is reduced, but the weight increases
Solution Approach 1:
The support function is segmented between multiple support members (first support member and second support member) positioned at different locations. The first support member supports the scintillator at a first position while the second support member supports it at a second position, distributing the mechanical support load and reducing distortion without requiring a single thick base structure.
Solution Approach 2:
Support members are introduced as intermediary elements between the base and the scintillator. These support members provide localized mechanical support to reduce scintillator distortion while maintaining a thin base structure, avoiding the need to increase base thickness for weight.
2Area of stationary object
If multiple imaging substrates are arranged to form a large area sensor panel, then the imaging area is increased, but deformation nonuniformity at joints increases
Solution Approach 1:
The support members are configured to provide differentiated support at specific positions. The first support member supports the scintillator at a first position while the second support member supports it at a second position, creating segmented support zones that address deformation nonuniformity at joints between imaging substrates.
Solution Approach 2:
Different support members are positioned at different locations to provide localized support where needed. This local quality approach addresses deformation nonuniformity specifically at joint regions between imaging substrates while maintaining overall panel stability across the large imaging area.
