Anatomical Region Rendering for Device-Tracked View Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The navigation of interventional devices in anatomy during medical procedures is challenging due to the need for manual adjustment of anatomical image perspectives, which complicates the mental mapping of intra-procedural images to pre-procedural volumetric images.
Innovation Solution
A system that selectively generates different perspectives of anatomical regions based on the tracked position of an interventional device within a volumetric representation, automatically adjusting the perspective to facilitate easier navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of anatomical image perspective is required, then the system can provide fixed perspective views, but the ease of operation deteriorates due to the need for manual zoom and orientation adjustments during procedures
Solution Approach 1:
The system automatically adjusts the perspective of the anatomical rendering based on the tracked position of the interventional device. The processor selectively generates different renderings corresponding to different perspectives without requiring manual user input, enabling the system to serve itself by autonomously adapting the view to the device location.
Solution Approach 2:
The system transitions from providing fixed perspective views to dynamically adjusting the rendering perspective in real-time based on the tracked position of the interventional device. This dynamic adaptation allows the view to automatically follow the device as it moves through the anatomical region.
2Ease of operation
If fixed perspective volumetric images are used, then the device complexity is reduced, but the ease of operation worsens due to difficulty in mental mapping during procedures
Solution Approach 1:
The system uses feedback from the tracked position of the interventional device to automatically adjust the rendering perspective. The processor receives position information and selectively generates appropriate renderings based on this feedback, creating a closed-loop system that adapts to the device location in real-time.
Solution Approach 2:
The system provides dynamic perspective adjustment that adapts to the moving interventional device, maintaining continuous spatial context information throughout the procedure. This dynamic rendering ensures that the anatomical view always corresponds to the current device position, eliminating the mental mapping difficulty.
3Ease of operation
If automatic perspective adjustment is implemented, then the ease of operation improves by eliminating manual adjustments, but the device complexity increases due to tracking and selective rendering requirements
Solution Approach 1:
The system automatically adjusts the perspective based on the tracked device position without requiring manual user input. The processor monitors the device location and selectively generates appropriate renderings autonomously, eliminating the need for operator intervention in perspective adjustment.
Solution Approach 2:
The system integrates multiple functions into a single cohesive system: it tracks the interventional device position, processes this information, and automatically generates appropriate renderings. This multi-functional approach consolidates what would otherwise require separate systems into one integrated solution.
