Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Endovascular treatment methods face challenges in converting three-dimensional blood vessel cross-sectional images to real-time projected images during procedures, leading to operator burden and potential mistakes, especially for new operators.
Innovation Solution
An image display apparatus that acquires volume data, creates cross-sectional and projected images, and uses a control unit to display specific points or lines on both image types, facilitating easier understanding of the three-dimensional positional relationship between blood vessel cross-sectional images and projected images, and an X-ray diagnostic apparatus that adjusts the X-ray source position based on specified points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the operator converts three-dimensional positional relationship between cross-sectional images and projected images mentally, then the treatment plan can be executed, but the operator burden increases and mistakes may occur
Solution Approach 1:
The patent introduces a computer-based image processing system as an intermediary between the cross-sectional images and projected images. The system automatically performs the complex spatial conversion and presents both images in a coordinated manner, eliminating the need for the operator to perform mental conversion while ensuring accurate treatment execution.
Solution Approach 2:
The patent replaces the operator's manual mental conversion process with an automated computer-based image processing system. The computer automatically calculates and displays the spatial relationships between cross-sectional and projected images, substituting the human cognitive process with a mechanical/computational system that is more reliable and less burdensome.
2Loss of information
If cross-sectional images and projected images are displayed separately, then image quality is maintained, but the three-dimensional positional relationship becomes difficult to understand
Solution Approach 1:
The patent combines the display of cross-sectional images and projected images into a unified interface. The computer processing unit coordinates both images to show their three-dimensional positional relationships simultaneously, allowing the operator to understand spatial relationships without sacrificing image quality or requiring complex separate display systems.

Data Source
AI summary
In an image display apparatus of this invention, an image creation unit creates a plurality of cross-sectional images and a projected image from the volume data acquired at a CT volume data acquisition unit. The plurality of cross-sectional images and projected image are displayed on a monitor. When a specific point on the plurality of cross-sectional images displayed on the monitor is clicked at an operation unit, a line is displayed on the projected image displayed on the monitor according to the click.
