Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for image segmentation, such as those described in US 2015/0155010 A1, are insufficiently efficient for users, particularly in medical imaging, as they rely on video-based instructions and do not optimize user interactions for faster and more accurate segmentation.
Innovation Solution
A system and method that analyze user interaction data to determine an optimized set of interactions using a graphical segmentation interface, generating candidate sets based on similarity and time metrics to provide users with a faster and more efficient segmentation process, potentially introducing new tools or parameter settings not initially used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If video-based instructions are provided to help users operate segmentation tools, then user guidance is improved, but user efficiency in obtaining segmentation remains insufficient
Solution Approach 1:
The system records user interactions with segmentation tools and provides feedback by suggesting optimized interaction sequences that achieved similar segmentations faster, allowing users to learn from actual optimized workflows rather than passive video instructions
Solution Approach 2:
The system automatically analyzes user interaction data and generates optimized interaction suggestions without requiring external training materials, enabling the system to self-improve and provide personalized efficiency enhancements to each user
2Measurement precision
If manual or semi-automatic interaction is used to correct automated segmentation, then segmentation accuracy is improved, but time consumption increases
Solution Approach 1:
The system pre-analyzes user interaction patterns and prepares optimized interaction sequences in advance, so when users need to correct automated segmentation, they can immediately apply proven efficient interaction patterns rather than experimenting in real-time
Solution Approach 2:
The system varies interaction parameters such as tool selection, parameter settings, and interaction sequences to find optimal combinations that achieve accurate segmentation faster, adapting to different segmentation scenarios and user skills
3Adaptability or versatility
If multiple segmentation tools with varying parameters are provided, then segmentation flexibility is improved, but interaction complexity increases
Solution Approach 1:
The system makes segmentation tools multi-functional by enabling each tool to operate with optimized parameters for different scenarios, reducing the need for users to manually configure multiple specialized tools while maintaining segmentation flexibility
Solution Approach 2:
The system automatically adjusts tool parameters based on the segmentation context and user interaction patterns, allowing a smaller set of tools to achieve the same versatility as many specialized tools would require, thereby reducing interaction complexity

AI summary
A system and a computer-implemented method are provided for segmenting an object in a medical image using a graphical segmentation interface. The graphical segmentation interface may comprise a set of segmentation tools for enabling a user to obtain a first segmentation of the object in the image. This first segmentation may be represented by segmentation data. Interaction data may be obtained which is indicative of a set of user interactions of the user with the graphical segmentation interface by which the first segmentation of the object was obtained. The system may comprise a processor configured for analyzing the segmentation data and the interaction data to determine an optimized set of user interactions which, when carried out by the user, obtains a second segmentation similar to the first segmentation, yet in a quicker and more convenient manner. A video may be generated for training the user by indicating the optimized set of user interactions to the user.
