Radiation Imaging Controller Switching Communication Settings by Measured Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing radiation imaging systems face challenges in maintaining controllability of radiation irradiation due to the lack of correlation between RSSI (Received Signal Strength Indicator) and actual communication time, leading to potential delays in signal transmission between the radiation imaging apparatus and the generation controller.
Innovation Solution
A radiation imaging system that includes a radiation imaging apparatus, an irradiation control apparatus, a communication control apparatus, and a controller. The system allows the radiation imaging apparatus to communicate with the communication control apparatus based on a setting selected from multiple settings by the controller. The controller acquires the communication time for a predetermined communication amount and switches the communication setting to improve communication efficiency.

Engineering Contradiction Analysis
1Reliability
If RSSI is used to select communication settings, then communication stability is improved, but actual communication speed does not improve due to lack of correlation with communication time
Solution Approach 1:
The patent changes the parameter used for communication setting selection from RSSI (signal strength indicator) to actual communication time. The controller measures the communication time for data transmission between the radiation imaging apparatus and generation controller, and selects communication settings based on this time parameter rather than signal strength, directly addressing the lack of correlation between RSSI and actual communication speed
Solution Approach 2:
The patent implements a feedback mechanism where the controller continuously monitors communication time between the radiation imaging apparatus and generation controller, and uses this feedback to dynamically adjust communication settings. This closed-loop control ensures that settings are optimized based on actual communication performance rather than static signal strength measurements
2Device complexity
If communication time is not monitored, then system complexity is reduced, but controllability of radiation irradiation decreases due to signal transmission delays
Solution Approach 1:
The patent applies preliminary action by having the controller pre-measure and evaluate communication times for different communication settings before actual radiation irradiation occurs. This allows the system to pre-determine the optimal communication setting that ensures timely signal transmission, so when radiation irradiation needs to be controlled, the system is already configured for reliable communication
Solution Approach 2:
The system performs self-service by automatically monitoring its own communication time and autonomously selecting optimal communication settings without requiring external intervention. The controller measures communication time between components and automatically adjusts settings to maintain controllability, reducing the need for complex external control mechanisms
