Medical Image Processing Apparatus for Angiography Interference Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional X-ray angiography systems for cerebral blood vessels face difficulties in accurately setting observation angles for both frontal and lateral radiography systems due to interference issues, with the "angle feedback" function only working in a single direction, requiring manual adjustments that are cumbersome and prone to interference.
Innovation Solution
A medical image processing apparatus that includes an image processing unit for acquiring 3D images, a projection direction input unit, an imaging direction setting unit, and an interference checking unit to determine and prevent interference between radiography systems, allowing for automated angle adjustments and minimizing manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual angle setting is used for the lateral radiography system, then the observation angle can be adjusted, but interference with the frontal radiography system occurs and the operation becomes cumbersome
Solution Approach 1:
The patent implements an angle feedback function that automatically transmits the observation angle set on the 3D-DSA image to the lateral radiography system. The system acquires the current angle of the lateral radiography system, calculates the difference between the set angle and current angle, and automatically adjusts the lateral radiography system angle to match the set angle, eliminating manual adjustment and interference issues
Solution Approach 2:
The lateral radiography system automatically adjusts its own angle based on the feedback from the 3D-DSA image without requiring manual intervention. The system self-corrects the angle by comparing the current angle with the target angle and automatically moving to the correct position
2Productivity
If automated angle feedback is implemented for both radiography systems, then operational efficiency improves, but system complexity increases
Solution Approach 1:
The patent extends the angle feedback function to work with both the frontal and lateral radiography systems using the same control apparatus. The system can switch between different radiography systems and apply the same angle feedback mechanism, making the control system multi-functional without requiring separate complex control systems for each radiography system

AI summary
An embodiment of the present invention provides a medical apparatus which displays an image of an object collected by using a first radiography system and a second radiography system, including: an image processing unit adapted to acquire a three-dimensional image; a projection direction input unit used to input a projection direction for at least one of the first radiography system and the second radiography system using the three-dimensional image; an imaging direction setting unit adapted to set an imaging direction for at least one of the first radiography system and the second radiography system based on the projection direction; and an interference checking unit adapted to determine whether interference between the first radiography system and the second radiography system will occur if one of the first radiography system and the second radiography system corresponding to the set imaging direction is moved.
