Real-time 3D Visualization of Interventional Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical imaging systems are unable to generate real-time three-dimensional images with sufficient resolution for interventional procedures, relying on inaccurate overlays of two-dimensional images onto static three-dimensional images, which are distracting and do not accurately represent the device's three-dimensional position within the body.
Innovation Solution
Generating a first three-dimensional image and then updating it by replacing voxels within a region of interest based on subsequent two-dimensional images, allowing for real-time three-dimensional visualization of the device during procedures while reducing computational requirements by focusing on the region of interest rather than the entire image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If real-time three-dimensional images are generated with sufficient resolution, then visualization accuracy is improved, but processing capability exceeds system capacity
Solution Approach 1:
The patent divides the three-dimensional image into multiple slices or sections along the longitudinal axis of the medical device. Each slice is processed independently and rendered separately, allowing the system to handle complex three-dimensional visualization tasks in smaller, more manageable units that fit within real-time processing constraints while maintaining overall image quality and accuracy.
2Productivity
If conventional overlay methods are used, then processing demands are reduced, but registration inaccuracies and representational quality deteriorate
Solution Approach 1:
The patent transitions from two-dimensional overlay methods to true three-dimensional visualization by rendering multiple cross-sectional slices that can be viewed from different angles and depths. This dimensional transformation eliminates the need for registration between two-dimensional and three-dimensional images, as the device is visualized natively in three dimensions with accurate spatial representation.
