3D Medical Image Segmentation with 1D Reference Path Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adjusting three-dimensional medical image segmentations is challenging due to difficulties in visualizing and modifying them on two-dimensional screens, requiring precise positioning of planes which can lead to inefficiencies and the need for repeated repositioning of slices.
Innovation Solution
A control element that allows for adjusting reference locations along a predetermined one-dimensional path within the three-dimensional segmentation, independent of two-dimensional slices, facilitating ergonomic and anatomically meaningful adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If two-dimensional slices are used to adjust three-dimensional segmentation, then the segmentation can be visualized on a screen, but the adjustment process requires iterative repositioning of slices and precise plane positioning which reduces efficiency
Solution Approach 1:
The patent introduces a one-dimensional slider control that operates independently from the two-dimensional slice display. This slider provides a direct interface for adjusting reference locations along a specific axis, allowing users to modify three-dimensional segmentation parameters without being constrained by slice positioning. The slider translates one-dimensional input directly into three-dimensional segmentation adjustments, bypassing the need for iterative slice repositioning while maintaining visualization capability.
2Loss of information
If two-dimensional slices are used for segmentation adjustment, then visualization is possible, but the user interface requires careful selection and repositioning of planes which degrades ergonomics
Solution Approach 1:
The patent introduces a slider control as an intermediary element between the user and the three-dimensional segmentation data. This slider acts as a mediator that translates simple one-dimensional user input into complex three-dimensional segmentation adjustments. The slider maintains the visualization capability through the two-dimensional slice display while providing an ergonomic interface that eliminates the need for users to manually position slices, thus improving ease of operation without sacrificing visualization.

AI summary
Disclosed herein is a medical system (100, 300) comprising a display (112) and a user interface (114). The execution of machine executable instructions (120) causes a processor (104) to: receive (200) three-dimensional medical image data (122) of an anatomical structure (128, 322); receive (202) a three-dimensional segmentation (124) with one or more reference locations (800); display (204) at least one two-dimensional slice (126) of the three-dimensional medical image data; render (206) a cross section (134) of the three-dimensional segmentation, provide (208) a control element (130) of the user interface that is configured for receiving a one-dimensional position of the at least one reference location along a predetermined one-dimensional path (806); receive (210) the one-dimensional position (137) from the control element; adjust (212) the three-dimensional segmentation (124) using the one-dimensional position; and update (214) the rendering of the cross section of the three-dimensional segmentation.
