X-ray Imaging Apparatus Blood Vessel Image Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray imaging apparatuses face challenges in clearly reflecting blood vessels in superimposed images, as the selection of blood vessel images may not accurately represent the relative position coordinate of fluoroscopic images, leading to unclear vessel reflections.
Innovation Solution
An X-ray imaging apparatus with a control unit that selects and generates a blood vessel image with the clearest reflection by comparing multiple images with the same relative position coordinate, allowing for precise superimposition with fluoroscopic images, including features like image processing, storage, and display units to ensure clear vessel visualization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If one blood vessel image is selected from multiple images with the same relative position coordinate, then the imaging process is simplified, but the blood vessel may not be clearly reflected in the selected image
Solution Approach 1:
The patent changes the selection criterion from arbitrary or simple parameter-based selection to selection based on blood vessel reflection clarity. The control unit evaluates multiple blood vessel images with the same relative position coordinate and selects the one where the blood vessel is most clearly reflected, thereby resolving the contradiction between simplification and clarity.
2Measurement precision
If multiple blood vessel images are captured and stored, then the likelihood of finding a clear blood vessel image increases, but the data storage and processing requirements increase
Solution Approach 1:
The patent extracts only the essential information needed for clear blood vessel visualization. Instead of storing and processing all captured images equally, the control unit evaluates multiple images with the same relative position coordinate and extracts/selects only the one with the clearest blood vessel reflection, thereby reducing storage and processing requirements while maintaining high clarity.
3Productivity
If blood vessel images are selected without considering reflection clarity, then the superimposition process is faster, but the visualization quality deteriorates
Solution Approach 1:
The patent performs preliminary evaluation of blood vessel reflection clarity before the superimposition process. The control unit automatically assesses multiple blood vessel images with the same relative position coordinate and pre-selects the one with the clearest reflection, so that the subsequent superimposition process can proceed quickly without compromising visualization quality.

Data Source
AI summary
This X-ray imaging apparatus includes a control unit for performing control to select one blood vessel image in which a blood vessel is clearly reflected from a plurality of blood vessel images stored in the storage unit when capturing a fluoroscopic image and performing control to display a superimposed image in which the selected blood vessel image and the fluoroscopic image are superimposed on the display unit.
