Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiation imaging systems face challenges in ensuring appropriate imaging conditions for preliminary exposures, leading to potential failures in capturing main exposure images due to inadequate determination of cumulative dose and irradiation time, resulting in inefficient use of exposure dose and potential subject exposure to inappropriate conditions.
Innovation Solution
An imaging control apparatus and system that acquires and compares first and second imaging conditions to ensure compatibility, preventing exposure if the second imaging condition does not fall within the first imaging condition range, and providing user notifications to adjust settings for optimal preliminary exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If preliminary exposure is performed at a lower dose to reduce subject exposure, then subject exposure is reduced, but the cumulative dose may be insufficient for accurate image analysis
Solution Approach 1:
The system performs preliminary exposure at a reduced dose before the main exposure, using the preliminary image to analyze imaging conditions and determine optimal main exposure parameters. This preliminary action allows the system to prepare appropriate imaging conditions while minimizing initial subject exposure.
Solution Approach 2:
The system changes exposure parameters between preliminary and main exposures. The preliminary exposure uses lower dose parameters, while the main exposure uses adjusted parameters determined by analyzing the preliminary image quality and imaging conditions, thereby optimizing both subject exposure and image analysis accuracy.
2Manufacturing precision
If the system performs image analysis after preliminary exposure to determine main exposure conditions, then main exposure accuracy is improved, but the preliminary exposure may be wasted if conditions are inappropriate
Solution Approach 1:
The system performs image analysis on the preliminary exposure image to evaluate imaging conditions, then uses this feedback to determine optimal main exposure conditions. The feedback loop includes analyzing image quality, comparing with reference images, and adjusting parameters accordingly, ensuring the preliminary exposure informs rather than wastes radiation dose.
Solution Approach 2:
The preliminary exposure serves as a preparatory action where imaging conditions are tested and evaluated. By performing image analysis immediately after preliminary exposure, the system determines optimal parameters for the main exposure before committing the higher dose, preventing waste of the main exposure dose on inappropriate conditions.
3Device complexity
If the system determines imaging conditions based solely on dose per unit time, then control is simplified, but cumulative dose assessment becomes inaccurate
Solution Approach 1:
The system replaces simple dose per unit time monitoring with comprehensive image analysis that evaluates actual imaging conditions. Instead of relying solely on mechanical dose tracking, the system uses image processing and comparison with reference images to accurately assess whether cumulative dose and imaging conditions are appropriate, substituting a more sophisticated measurement approach.

AI summary
An imaging control apparatus includes a hardware processor that acquires a first imaging condition set as a imaging condition for a preliminary exposure performed prior to a main exposure that performs an exposure of radiation on a subject, and the hardware processor performs control based on compatibility of the acquired first imaging condition and a second imaging condition input as an imaging condition for the subject.
