Solution Overview
Problem
Existing radiation imaging apparatuses have limited versatility as they only consider the operation of reading out charges from both detection units simultaneously, lacking flexibility in modes of operation.
Innovation Solution
A radiation imaging apparatus with a control unit that selects from multiple modes, allowing either both detection units to capture radiation images or only the first detection unit to capture an image, optimizing power consumption and operational flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the radiation imaging apparatus operates in a mode where both detection units capture radiation images simultaneously, then the functionality and application scope are enhanced, but the power consumption increases
Solution Approach 1:
The system dynamically switches between dual-detection mode and single-detection mode based on operational requirements. The control unit activates only the necessary detection unit(s), making the system's configuration flexible and adaptable rather than fixed, thereby optimizing power consumption while maintaining functionality.
Solution Approach 2:
The system changes the operational parameter of detection unit activation by controlling the potential distribution in the semiconductor layer. By adjusting which detection unit is active (first, second, or both), the system optimizes power consumption while maintaining the necessary imaging functionality for different application scenarios.
2Adaptability or versatility
If the radiation imaging apparatus is designed to support multiple operation modes, then the versatility is improved, but the device complexity increases
Solution Approach 1:
The radiation imaging apparatus is designed with universal control capabilities that can operate in multiple modes (dual-detection mode and single-detection mode) using the same basic hardware architecture. The control unit universally manages potential distribution regardless of which detection unit is active, simplifying the overall system design while achieving versatility.
Solution Approach 2:
The invention extracts and utilizes the inherent capability of the semiconductor layer to function as multiple detection units through potential control alone, without requiring separate complex control circuits for each detection unit. This extraction of functionality from the semiconductor material itself reduces overall device complexity while maintaining multi-mode operation capability.
