Radiation Detector Sensor Panel Buffer Member Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radiation detection apparatuses with back-side irradiation structures face challenges in withstanding externally applied loads, particularly when a subject lies on them, as stress is applied to the sensor panel, potentially causing damage due to the mismatch in dimensions between the scintillator and sensor panel.
Innovation Solution
A radiation detection apparatus design featuring a housing with a member positioned between the sensor panel and the scintillator, where the member's outer edge is inside the scintillator's outer edge, providing a buffer action to reduce shock and stress transmission, thereby protecting the sensor panel from damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the sensor panel is made larger than the scintillator to accommodate peripheral circuits and electrodes, then the sensor panel can perform its detection function, but stress is applied to the non-contact portion during external loading, potentially causing damage
Solution Approach 1:
A buffer member is introduced as an intermediary component between the sensor panel and the scintillator. This buffer member absorbs and distributes the stress applied during external loading, preventing direct transmission of stress to the non-contact portion of the sensor panel where the scintillator and sensor panel do not overlap, thereby protecting the sensor panel from damage while maintaining its larger size for peripheral circuit accommodation
Solution Approach 2:
The buffer member is positioned in advance between the sensor panel and scintillator to provide preemptive protection. When external loads are applied (such as when a patient lies on the apparatus), the buffer member is already in place to cushion and distribute the stress before it can reach the vulnerable non-contact portions of the sensor panel, preventing damage before it occurs
