Radiation Imaging Failure Diagnosis Using Irradiation Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiation imaging systems fail to identify the cause of imaging failures, such as dark images, leading to potential re-imaging issues without clear guidance for operators.
Innovation Solution
A radiation imaging system that includes a control apparatus to determine the cause of dark images by analyzing irradiation information, including radiation dose data, to provide clear guidance for re-imaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a control method is implemented to determine whether imaging is successful and display a re-imaging screen when imaging fails, then the time and action before re-imaging are reduced, but the factor of the imaging failure remains unclear and operators cannot recognize what to do at the time of re-imaging
Solution Approach 1:
The system implements feedback by acquiring irradiation information from the radiation generation apparatus and comparing it with expected values to determine the factor of imaging failure. The control apparatus then provides feedback to the operator by displaying both the re-imaging screen and the determined failure factor, enabling the operator to understand what went wrong and how to correct it for successful re-imaging.
Solution Approach 2:
The control apparatus acts as an intermediary between the radiation generation apparatus and the radiation imaging apparatus. It acquires irradiation information from the generation apparatus, determines the failure factor through comparison and analysis, and communicates this information to the operator, thereby bridging the information gap that would otherwise exist between the imaging system components.
2Productivity
If re-imaging is performed without clear guidance on the failure cause, then imaging can be attempted again quickly, but imaging may fail again due to lack of operator understanding
Solution Approach 1:
The control apparatus provides feedback to the operator by displaying the determined factor of imaging failure alongside the re-imaging screen. This feedback loop enables operators to understand the cause of failure and take appropriate corrective actions, thereby improving the reliability of re-imaging while maintaining quick turnaround time.
Solution Approach 2:
The system performs preliminary analysis of the imaging failure by acquiring and comparing irradiation information before the operator initiates re-imaging. By determining the failure factor in advance and presenting it to the operator, the system enables informed re-imaging decisions and appropriate corrective actions to be taken before the next imaging attempt.

AI summary
A radiation imaging system includes a radiation imaging apparatus configured to generate a radiation image based on radiation emitted from a radiation generation apparatus, and a control apparatus configured to acquire information from the radiation imaging apparatus and the radiation generation apparatus. The control apparatus includes an image determination unit configured to determine whether the radiation image acquired from the radiation imaging apparatus is a failed image, an irradiation information acquisition unit configured to acquire irradiation information from the radiation generation apparatus, and a factor determination unit configured to determine a factor in acquisition of the failed image, based on a determination result of the image determination unit and information in the irradiation information acquisition unit.
