Solution Overview
Problem
Current radiation imaging systems face challenges in handling sudden imaging requests and maintaining functionality when the command communication control apparatus is not started or has failed, due to the complexity of setting and managing imaging parameters such as pixel sensitivity, non-destructive reading, binning settings, and accumulation time, especially in large-area flat panel type sensors.
Innovation Solution
A radiation imaging control apparatus with a first communication unit for Ethernet communication, a second communication unit for bidirectional serial optical communication, and control units for setting and processing imaging parameters, allowing for automatic switching to an emergency imaging mode and enabling imaging operations even without command communication, using a CMOS type image sensor with a rectangular semiconductor substrate configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If command communication control apparatus is used to set imaging parameters, then imaging precision and control are improved, but system complexity and operational difficulty increase
Solution Approach 1:
The radiation imaging apparatus autonomously determines and sets imaging parameters based on imaging mode information received from the external control apparatus, without requiring manual intervention or complex command communication protocols. The apparatus self-adjusts parameters such as pixel sensitivity, binning settings, and accumulation time according to the selected imaging mode.
Solution Approach 2:
Multiple imaging modes are pre-configured with optimized parameter sets. When an imaging mode is selected, the corresponding parameters are automatically applied, eliminating the need for real-time parameter tuning and reducing system complexity during operation.
2Reliability
If multiple imaging parameters are manually configured, then imaging performance is optimized, but operational time and user burden increase
Solution Approach 1:
Imaging parameters are pre-configured for each imaging mode before operation. When a mode is selected, the corresponding parameters are automatically applied without requiring manual configuration, thus optimizing imaging performance while minimizing operational time.
Solution Approach 2:
The system dynamically switches between pre-configured parameter sets based on the selected imaging mode, allowing rapid adaptation to different imaging requirements without manual reconfiguration. This enables fast switching between modes such as high sensitivity, high speed, and wide dynamic range imaging.
3Ease of operation
If command communication is required for imaging operations, then system control is centralized, but system reliability decreases when control apparatus fails
Solution Approach 1:
The control system is segmented into independent functional modules: the external control apparatus handles high-level imaging mode selection, while the radiation imaging apparatus autonomously manages parameter configuration and execution. This modular architecture ensures that failure of the control apparatus does not prevent the imaging apparatus from operating with its last known good settings.
Solution Approach 2:
The radiation imaging apparatus maintains the ability to autonomously determine and execute imaging parameters even when disconnected from the control apparatus. The apparatus can continue operating in emergency imaging mode using internally stored parameter sets, ensuring system reliability and availability.
4Speed
If Ethernet communication is used for parameter transmission, then data transmission speed is improved, but communication reliability and real-time control are reduced
Solution Approach 1:
The communication system uses Ethernet for high-speed bulk data transmission of imaging parameters and mode information, while reserving bidirectional serial optical communication lines for critical real-time control signals and synchronization. This segmentation allows each communication channel to be optimized for its specific function, achieving both high speed and high reliability.

AI summary
