Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray diagnosis apparatuses face challenges in imaging large sites, such as the spine or leg, as the size of the imaging range is finite, making it difficult to capture the entire area in a single shot, and current long image stitching techniques can be cumbersome to set up and execute effectively.
Innovation Solution
An X-ray diagnosis apparatus with a movable X-ray detector and generator, controlled by processing circuitry, that sets multiple overlapping imaging ranges and generates stitched images by emitting X-rays across these ranges, allowing for easy and appropriate setup and imaging of large areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If long image stitching is used to image large sites, then the entire examined site can be captured, but the setup and operation becomes complex and difficult
Solution Approach 1:
The patent divides the large examination area into multiple smaller imaging ranges that are captured sequentially. The X-ray detector captures multiple partial images of different regions, which are then stitched together to form a complete image of the entire large site, making the operation simpler while maintaining large area coverage
Solution Approach 2:
The system automatically determines the optimal imaging ranges and stitching parameters without requiring complex manual setup by the operator. The processing circuitry autonomously configures the multiple imaging ranges and performs the stitching operation, eliminating the need for operators to manually configure complex parameters
2Adaptability or versatility
If manual setting of imaging ranges is used, then flexibility is maintained, but the operation becomes time-consuming and error-prone
Solution Approach 1:
The system pre-determines the optimal imaging ranges and stitching parameters based on the examination type and detector characteristics before actual imaging begins. This preliminary configuration eliminates the need for time-consuming manual setup during the imaging process while maintaining adaptability to different examination scenarios
3Area of stationary object
If multiple imaging ranges are set manually, then complete coverage is possible, but alignment and stitching become difficult
Solution Approach 1:
The system uses feedback from the captured images to automatically adjust and refine the alignment of multiple imaging ranges. The processing circuitry analyzes the overlapping regions between adjacent images and performs precise geometric transformations to ensure accurate stitching, eliminating manual alignment errors
