Radiation Imaging Synchronization via Preliminary Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing radiation imaging systems face challenges in accurately synchronizing radiation irradiation with the operation of radiation imaging apparatuses due to message loss or delay over network lines, leading to reduced synchronization accuracy and potential unnecessary exposure.
Innovation Solution
The system employs a communication network with wired and wireless communication units to synchronize the radiation imaging apparatus and irradiation control apparatus, using timekeeping control units to manage radiation detection and irradiation timing, ensuring that radiation imaging occurs only when synchronization is confirmed, and stopping irradiation if synchronization is not achieved to prevent unnecessary exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If messages are transmitted and received over a network line for synchronization, then the radiation imaging apparatus can be synchronized with the radiation generating apparatus, but message loss or delay occurs leading to reduced synchronization accuracy
Solution Approach 1:
The system performs preliminary synchronization checks before radiation irradiation by verifying that the image receiver is in the accumulation state and ready to receive radiation. The control apparatus confirms synchronization status in advance and only permits irradiation when synchronization is verified, preventing message loss or delay from affecting the actual irradiation timing.
Solution Approach 2:
The system implements a feedback mechanism where the radiation imaging apparatus continuously reports its operational state (accumulation state, reading state, resetting) to the irradiation control apparatus. The control apparatus uses this feedback to determine whether synchronization is achieved and whether radiation irradiation should proceed, ensuring reliable synchronization despite network message issues.
2Productivity
If the image receiver continuously accumulates electric charges, then radiation detection is ready, but unnecessary radiation exposure occurs when synchronization is not achieved
Solution Approach 1:
The system takes preliminary anti-action by preventing radiation irradiation when synchronization is not achieved. The control apparatus monitors the image receiver state and only permits irradiation when the receiver is confirmed to be in the accumulation state, thereby avoiding unnecessary radiation exposure while maintaining detection readiness.
Solution Approach 2:
The image receiver provides continuous feedback about its operational state to the control apparatus. This feedback mechanism allows the system to determine when the receiver is ready for radiation detection and when irradiation should be permitted, preventing unnecessary exposure while maintaining productivity.
3Device complexity
If the image receiver operates without an electronic shutter, then the structure is simpler, but light entering during reading or resetting ruins the image
Solution Approach 1:
The system performs preliminary action by controlling the timing of radiation irradiation to coincide with the image receiver's accumulation state. The control apparatus ensures that radiation is only irradiated when the receiver is ready and will not be affected by stray light, maintaining image quality without requiring an electronic shutter.
Solution Approach 2:
The control apparatus acts as an intermediary between the image receiver and the radiation generating apparatus. It coordinates their operations to ensure that radiation irradiation occurs only when the image receiver is in the appropriate state, preventing light contamination while maintaining simple receiver structure.

AI summary
A radiation imaging apparatus comprising a detection unit arranged to detect radiation from an irradiation unit arranged to irradiate with the radiation; a reception unit configured to receive, from an external apparatus, irradiation information about an irradiation time at which irradiation of the radiation is to be started; a control unit configured to control the detection unit so that the detection unit is ready to detect the radiation at the irradiation time, based on the irradiation information; and a transmission unit configured to transmit photographing permission information, which indicates that the detection unit is ready to detect the radiation at the irradiation time, to the external apparatus if the detection unit is expected to be ready to detect the radiation at the irradiation time.
