Interventional Device Tracking Display With Auto Field-of-View Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing position tracking technologies for interventional devices in anatomical regions require manual adjustment of anatomical imaging modalities to maintain the device within the field of view, which is inefficient and disruptive during minimally invasive procedures.
Innovation Solution
A position tracker driven display system that autonomously selects and updates real-time images of the interventional device's navigation within the anatomical region based on position tracking data, using OSS, EM, or InSitu sensors, without manual adjustment of imaging modalities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment of fluoroscopic imaging is used to track interventional device position, then the device can be kept within field of view, but procedural efficiency decreases and manual intervention is required
Solution Approach 1:
The system automatically updates the fluoroscopic imaging field of view based on position tracking data from the interventional device, eliminating the need for manual adjustment by operators. The imaging system serves itself by autonomously repositioning to maintain the device within the field of view, thereby improving procedural efficiency while maintaining tracking accuracy.
2Loss of information
If manual adjustment of imaging modality is performed to maintain device in field of view, then device visibility is preserved, but procedural disruption increases
Solution Approach 1:
The system continuously monitors the position of the interventional device using position tracking technology and uses this feedback to automatically adjust the fluoroscopic imaging field of view. This closed-loop feedback mechanism ensures the device remains visible within the field of view without causing procedural disruption, as the adjustment occurs automatically based on real-time position data.
3Measurement precision
If fluoroscopic imaging is manually updated to track device position, then device location can be monitored, but system complexity increases due to manual operation requirements
Solution Approach 1:
The system replaces the manual mechanical operation of adjusting fluoroscopic imaging with an automated computer-controlled system. The imaging modality is repositioned automatically based on position tracking data, substituting manual mechanical adjustments with an automated control system that reduces operational complexity while maintaining monitoring accuracy.

AI summary
A position tracker driven display system for an interventional device (50) including an integration of one or more position trackers and one or more interventional tools. The position tracker driven display system employs a monitor (121) and a display controller (110) for controlling a real-time display on the monitor (121) of a tracking image illustrative of a navigation of a tracking node of the interventional device (50) within an anatomical region. The display controller (110) autonomously selects the tracking image among a plurality of registered spatial images illustrative of the anatomical region within an image space based on position tracking data informative of a position of the at least one position tracker within the anatomical region. The display controller (110) derives the autonomous selection of the tracking image from a position of the tracking node of the interventional device (50) relative to the image space as indicated by the position tracking data.
