Solution Overview
Problem
Existing radiographic systems face challenges in correcting composite images when radiation detection apparatuses with different inner structures are used together, as the structural shadows from these apparatuses can obstruct diagnoses and vary significantly in complexity, leading to inconsistent image quality.
Innovation Solution
A radiographic system comprising multiple radiation detection apparatuses, a composition processor, and an image corrector that generates composite images and corrects areas with structural shadows based on the specific characteristics of each apparatus's inner structure, using identification codes to determine appropriate correction methods for simple or complex structural shadows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If radiation detection apparatuses with different inner structures are used together for long-length imaging, then the observation area can be extended, but the structural shadows from these apparatuses vary significantly in complexity, leading to inconsistent image quality and making uniform correction difficult
Solution Approach 1:
The patent segments the correction process by creating separate correction data for each radiation detection apparatus based on its specific inner structure. The composite image is divided into multiple areas, each corresponding to a specific apparatus, and correction is applied independently to each area using apparatus-specific correction data, thereby maintaining image quality consistency across apparatuses with different structures.
Solution Approach 2:
The patent applies local quality by using different correction methods and parameters for different regions of the composite image. Each region corresponds to the imaging area of a specific radiation detection apparatus, and the correction is tailored to the local structural characteristics of that apparatus, ensuring optimal correction for each local area rather than applying a uniform correction across the entire composite image.
2Ease of operation
If a uniform correction method is applied to all radiation detection apparatuses, then the correction process is simplified, but the structural shadows vary significantly due to different inner structures, resulting in inadequate correction for complex structures
Solution Approach 1:
The patent performs preliminary action by pre-acquiring correction data for each radiation detection apparatus before actual imaging. The correction data, which reflects the specific inner structure of each apparatus, is obtained in advance and stored for later use. This preliminary preparation enables accurate correction without complicating the actual correction process during imaging operations.
Solution Approach 2:
The patent uses copying by creating correction data that represents the structural shadow characteristics of each radiation detection apparatus. This correction data serves as a template or copy of the apparatus's structural features, which can be applied repeatedly to correct images from the same apparatus, simplifying the correction process while maintaining accuracy for each specific apparatus type.
3Manufacturing precision
If correction data is acquired for each specific radiation detection apparatus, then correction accuracy for complex structural shadows is improved, but the system complexity increases due to managing multiple apparatus-specific correction datasets
Solution Approach 1:
The patent merges the management of multiple apparatus-specific correction datasets by integrating them into a unified correction system. The correction data from multiple apparatuses is combined with the composite image data in a coordinated manner, where the system automatically identifies which correction data to apply based on the imaging area, thereby managing complexity through systematic integration rather than separate handling of each dataset.
Solution Approach 2:
The patent uses an intermediary approach by introducing a correction data management mechanism that acts as a mediator between the multiple apparatus-specific correction datasets and the composite image processing. This intermediary system coordinates the selection and application of appropriate correction data, simplifying the management complexity while maintaining the accuracy benefits of apparatus-specific correction.
