Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The abrupt change in distances between marginal detector crystals of adjacent detecting modules and the radiation source's target point in radiation inspection systems affects the quality of inspection images generated, leading to suboptimal imaging results.
Innovation Solution
The radiation inspection system employs a detector arm with detecting modules having different preset included angles relative to a reference straight line on the circuit board, allowing for adjustable mounting positions that reduce or eliminate abrupt changes in distance, ensuring clearer imaging without the need for larger mounting angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If detecting modules are mounted at different mounting angles to directly face the radiation source beam direction, then the detection coverage is improved, but the distances between marginal detector crystals of adjacent detecting modules and the target point exhibit abrupt changes, degrading image quality
Solution Approach 1:
The patent changes the preset included angle parameter of detector crystals in detecting modules. By adjusting this angle parameter, the system achieves direct facing of detecting modules toward the radiation source beam direction while eliminating abrupt distance changes between marginal detector crystals and the target point, thus improving image quality without sacrificing detection coverage
Solution Approach 2:
The patent applies different preset included angles to different detecting modules based on their specific mounting positions. Each detecting module is configured with a locally optimized angle that matches its position on the detector arm, ensuring that marginal detector crystals maintain appropriate distances to the target point while still achieving comprehensive detection coverage
