Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging systems face usability issues when the imaging cycle of angiographic images and the rotation cycle of cross-sectional images do not coincide, leading to difficulties in correlating and displaying X-ray and cross-sectional images accurately, which hinders the ability to specify positions within blood vessels.
Innovation Solution
An imaging apparatus with a holding unit for X-ray images, a first generation unit for generating cross-sectional moving images based on rotation cycles, and a display unit for synchronizing X-ray and cross-sectional moving images at frame rates, ensuring mutual correlation and effective storage and display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the imaging cycle of angiographic images and the rotation cycle of cross-sectional images are made to coincide, then the correlation and synchronization between X-ray and cross-sectional images is improved, but the system becomes less flexible when different imaging speeds are required
Solution Approach 1:
The patent introduces an image processing apparatus as an intermediary between the X-ray imaging system and the cross-sectional imaging system. This intermediary receives images from both systems at different cycles, performs synchronization processing, and outputs correlated images. This mediator resolves the timing mismatch without requiring the imaging systems themselves to operate at synchronized cycles, thus maintaining both reliability of correlation and flexibility of independent operation.
2Speed
If the imaging cycle is shortened to capture more dynamic changes in blood vessels, then the temporal resolution is improved, but the complexity of synchronizing multiple image sources increases
Solution Approach 1:
The patent creates a copied and adapted version of images from one system to match the timing of another system. The image processing apparatus generates synthetic image sequences by selecting, interpolating, or repeating frames from the original high-speed imaging to create a downscaled version that synchronizes with the slower system. This copying approach allows high temporal resolution data to be utilized while simplifying the synchronization requirement.
3Ease of operation
If separate processing is used for X-ray images and cross-sectional images, then the processing flexibility is maintained, but the usability for correlated analysis is reduced
Solution Approach 1:
The patent merges the separately processed X-ray images and cross-sectional images into a single correlated output stream. The image processing apparatus takes independently processed images from both systems and combines them with spatial and temporal correlation, producing a unified display that shows both image types in registered positions. This merging occurs at the output stage, preserving the flexibility of separate processing while achieving the usability benefits of integrated correlated analysis.
