Freehand Render Start Line for Ultrasound Volume Rendering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ultrasound imaging techniques require time-consuming manual steps for volume rendering, often resulting in undesirable obstructions due to the use of straight or pre-defined render start lines, which hinder the generation of clear volume renderings.
Innovation Solution
A system and method that provide freehand render start line drawing tools and automatic render preset selections, allowing operators to draw a render start line and automatically select presets based on pixel intensity values to generate volume renderings that avoid obstructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual preset selection and straight render start lines are used, then volume rendering can be generated, but the process is time-consuming and may include obstructions
Solution Approach 1:
The system automatically selects render presets and generates render start lines based on analysis of the ultrasound image data, eliminating the need for manual operator intervention in these steps. The processor analyzes the image to identify suitable presets and generates optimized render start lines, allowing the system to serve itself rather than requiring continuous manual control.
Solution Approach 2:
The system performs preliminary analysis of the ultrasound image to pre-select appropriate render presets and pre-generate render start lines before the actual volume rendering process begins. This preliminary preparation work is done automatically based on image characteristics, so when rendering is initiated, the process can proceed quickly without manual delays.
2Reliability
If straight render start lines are used, then volume rendering can be generated, but obstructions may be included in the rendering
Solution Approach 1:
The render start line is transformed from a fixed straight line to a dynamic curve that adapts to the specific anatomical structures in the ultrasound image. The processor generates curved render start lines that bend around identified obstructions, allowing the rendering to dynamically adjust to the image content rather than following a rigid predetermined path.
Solution Approach 2:
The render start line is made locally adaptive, with different sections of the line having different curvatures and positions optimized for specific regions of the image. The processor analyzes local image features and adjusts the render start line geometry in different areas to avoid local obstructions while maintaining overall rendering quality.
