Parallel X-Ray Wire Mask Generation for Fluoroscopy Roadmap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing X-ray diagnosis apparatuses face challenges in improving the operability of the fluoroscopy roadmap function, particularly in displaying fluoroscopy roadmap images immediately after initiating the fluoroscopy process, due to the time required for generating wire mask images, which can lead to cumbersome user experience and unsatisfactory visibility of medical devices within the images.
Innovation Solution
The apparatus is configured to generate wire mask images in parallel with the acquisition of live images, using a predetermined number of frames to calculate an arithmetic mean, and then perform difference calculations between these images to display fluoroscopy roadmap images immediately after the fluoroscopy button is pressed, thereby reducing the time needed for wire mask image generation and enhancing visibility of medical devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If wire mask images are generated sequentially before fluoroscopy roadmap images, then image quality is improved, but time delay increases
Solution Approach 1:
The system performs preliminary actions by generating wire mask images in parallel with live image acquisition using a predetermined number of frames. This allows the wire mask images to be prepared in advance while maintaining image quality, thereby reducing the time delay when fluoroscopy roadmap images are needed.
2Loss of time
If wire mask image generation is performed in parallel with live image acquisition, then time delay is reduced, but processing complexity increases
Solution Approach 1:
The processing system is segmented into multiple independent processing streams: one for acquiring live images and another for generating wire mask images from a predetermined number of frames. This segmentation allows parallel processing without requiring complex inter-dependent processing logic, thereby reducing overall processing complexity while maintaining reduced time delay.
3Loss of information
If difference calculation is performed between live images and wire mask images, then medical device visibility is improved, but calculation time increases
Solution Approach 1:
The difference calculation between live images and wire mask images is performed continuously in parallel with image acquisition. This continuous processing ensures that medical device visibility is improved through real-time difference imaging without adding significant calculation time delays, as the processing occurs concurrently rather than sequentially.
