3D Anatomic Model Bridging for Reconnecting Isolated Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional user interfaces for planning medical procedures fail to accurately model anatomic passageways due to isolated structures that are not connected to the rest of the model, which can interfere with navigation and planning, particularly if they are near target sites.
Innovation Solution
A graphical user interface that allows operators to view and reconnect isolated structures to linked structures in a 3D model by providing input on connection locations, using algorithms to generate a bridge structure based on operator input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated algorithms are used to generate 3D anatomic models from medical images, then modeling efficiency is improved, but isolated structures may be incorrectly disconnected from the rest of the model
Solution Approach 1:
The system introduces a bridge structure as an intermediary element that connects isolated anatomic structures to the main model. The bridge structure serves as a mediator that reconciles the disconnected components, allowing automated algorithms to maintain efficiency while correcting accuracy issues through the intermediary connection mechanism.
Solution Approach 2:
The system implements feedback by detecting isolated structures in the generated 3D model and providing opportunities for operator review and correction. The feedback loop allows the system to identify modeling errors and enable corrective actions, ensuring that isolated structures are properly connected while maintaining the benefits of automated generation.
2Ease of operation
If conventional user interfaces are used for procedure planning, then ease of operation is maintained, but the ability to accurately reconnect isolated structures is limited
Solution Approach 1:
The graphical user interface is designed with multi-functionality, serving both as a simple visualization tool for ease of operation and as a sophisticated editing environment for accurate structural reconnection. The interface universally handles both viewing and editing tasks, allowing operators to maintain usability while achieving precise anatomical reconNECTION through integrated tools.
3Loss of time
If isolated structures are left disconnected in the model, then model generation time is reduced, but navigation accuracy during medical procedures is compromised
Solution Approach 1:
The system performs preliminary detection of isolated structures during the model generation process, before finalization. By identifying disconnected components early, the system allows for subsequent correction without significantly increasing overall generation time, ensuring navigation accuracy is maintained while minimizing time loss.

AI summary
Devices, systems, methods, and computer program products for performing medical procedures are disclosed herein. In some embodiments, a system for planning a medical procedure is configured to receive a three-dimensional (3D) model of an anatomic region of a patient. The 3D model can include a set of linked structures and at least one isolated structure spaced apart from the linked structure. The system can output a graphical representation of the linked structures and the at least one isolated structure, and can receive operator input indicating a set of locations on the graphical representation. The set of locations can represent a connection between the at least one isolated structure and the linked structures. Based on the operator input, the system can generate a bridge structure connecting the at least one isolated structure to the linked structures.
