Radiation Imaging AEC Control to Avoid Irradiation Start Delays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiation imaging systems experience delays in starting irradiation due to the need for immediate offset data acquisition for automatic exposure control, which reduces examination efficiency.
Innovation Solution
A radiation imaging system that selectively obtains offset data based on the use of automatic exposure control, allowing for immediate irradiation initiation when AEC is employed and omitting unnecessary data acquisition when AEC is not used, thereby reducing delays.

Engineering Contradiction Analysis
1Measurement precision
If offset data is obtained before irradiation for automatic exposure control, then measurement precision of irradiation dose is improved, but loss of time occurs due to delay in irradiation start
Solution Approach 1:
The system dynamically adjusts the offset data acquisition process based on whether AEC is enabled. When AEC is active, offset data is obtained before irradiation to ensure measurement precision. When AEC is not active, the system skips offset data acquisition to eliminate time delay, making the system flexible and adaptive to different operational modes.
Solution Approach 2:
The system changes the operational parameter of offset data acquisition based on the AEC status. By detecting whether AEC is enabled, the system modifies its behavior: obtaining offset data when AEC is enabled for precise measurement, and omitting it when AEC is disabled to reduce time loss.
2Reliability
If offset data obtaining is performed before irradiation, then reliability of automatic exposure control is improved, but productivity decreases due to reduced examination efficiency
Solution Approach 1:
The system dynamically adapts its offset data acquisition behavior based on AEC status. When AEC is enabled, the system performs offset data acquisition to ensure reliable automatic exposure control. When AEC is not enabled, the system skips this step to improve examination efficiency, thus balancing reliability and productivity based on operational requirements.
Solution Approach 2:
The system changes the parameter of offset data acquisition execution based on whether AEC is active. This conditional parameter change ensures that offset data is obtained only when necessary for AEC reliability, while avoiding unnecessary delays that would reduce productivity when AEC is not in use.
3Measurement precision
If offset data is obtained for detecting pixel, then measurement precision of radiation dose is improved, but loss of time occurs due to unnecessary data acquisition when AEC is not used
Solution Approach 1:
The system extracts and separates the offset data acquisition step from the mandatory irradiation preparation process. By making offset data acquisition conditional on AEC status, the system removes unnecessary data acquisition steps when AEC is not used, thereby eliminating time delays while preserving measurement precision when AEC is active.
Solution Approach 2:
The system changes the execution parameter of offset data acquisition based on AEC status. When AEC is enabled, offset data is obtained for precise radiation dose detection. When AEC is disabled, the system omits offset data acquisition to avoid time delays, thus adapting the measurement process to actual operational needs.

AI summary
A radiation imaging system includes a radiation imaging apparatus having a function of automatic exposure control and a control apparatus, and in the radiation imaging apparatus, offset data for a detecting pixel used for the automatic exposure control is obtained before permission to start irradiation after reception of a start request signal. The system determines whether to perform the automatic exposure control, permits start of irradiation after the offset data is obtained if it is determined that the automatic exposure control is performed, and permits start of irradiation upon omitting obtaining of the offset data if it is determined that the automatic exposure control is not performed.
