Graphical User Interface for Image-Guided Medical Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack an intuitive graphical user interface for effectively controlling and managing flexible and/or steerable elongate medical devices during minimally invasive procedures, particularly in navigating complex anatomical passageways.
Innovation Solution
A method and system that utilize a graphical user interface to display a reduced anatomical representation of the patient's anatomy, including a 3D representation of passageways and a route to a target location, allowing for real-time position information and anomaly detection, thereby enhancing the control and navigation of medical instruments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a full 3D anatomical representation with all passageways is displayed, then complete anatomical information is provided, but the interface becomes complex and difficult to navigate
Solution Approach 1:
The anatomical representation is segmented into multiple hierarchical levels: a simplified linear overview showing the complete route, and detailed 3D views of specific passageway segments. The system divides the complex anatomy into manageable portions that can be explored in detail while maintaining context of the overall structure.
Solution Approach 2:
The system transitions between different dimensional representations - a 1D linear anatomical representation for overview navigation, and 3D detailed views for examining specific passageways. This dimensional switching allows users to navigate the complete anatomy easily while accessing detailed information when needed.
2Measurement precision
If real-time position tracking and anomaly detection are implemented, then navigation accuracy is improved, but system complexity increases
Solution Approach 1:
A graphical user interface acts as an intermediary between the complex tracking systems and the user. The interface receives data from multiple sensors (electromagnetic tracking, optical tracking, force sensors), processes this information, and presents it in a simplified visual format showing instrument position and detected anomalies without requiring users to understand the underlying complex measurement systems.
Solution Approach 2:
The system automatically detects anomalies such as unintended tissue contact or deviation from the planned route by continuously monitoring sensor data and comparing it against expected parameters. This self-monitoring capability provides real-time feedback without requiring constant manual verification by the operator.
Data Source
AI summary
A system comprises a display system, a user input device, and one or more processors. The one or more processors are configured to perform operations including receive an anatomical model, receive a user input via the user input device associated with a target relative to the anatomical model, determine an uncertainty zone associated with the target, and display the target relative to the anatomical model via the display system. The uncertainty zone is displayed as at least partially surrounding the target.
