Medical Device Guidance Visual Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical device guidance systems lack intuitive visual feedback for healthcare providers to accurately position and orient medical devices within tissue during medical procedures.
Innovation Solution
A free-hand medical device guidance system that provides manual control over medical devices, offering visual displays to enhance the spatial relationships between the target, medical device, and ultrasound image, allowing operators to adjust the device's position, orientation, or trajectory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional medical device guidance systems are used, then device placement is performed without advanced visual feedback, but healthcare providers lack intuitive spatial awareness of device position and orientation
Solution Approach 1:
The system creates a virtual copy of the medical device and the patient's anatomy through 3D reconstruction from ultrasound images. This virtual model is displayed on a screen, allowing healthcare providers to see the precise position and orientation of the physical device in real-time without adding physical complexity to the actual procedure. The virtual device representation mirrors the physical device's location and orientation, providing intuitive spatial awareness.
Solution Approach 2:
The system transitions from 2D ultrasound images to a 3D virtual representation of both the anatomy and the medical device. By reconstructing three-dimensional models from multiple 2D ultrasound slices, the system provides comprehensive spatial information that helps providers understand device position in all three dimensions, improving both accuracy and intuitiveness simultaneously.
2Adaptability or versatility
If manual control over medical devices is maintained, then operator flexibility is preserved, but spatial relationship awareness between target, device, and ultrasound image deteriorates
Solution Approach 1:
The system provides real-time visual feedback by continuously updating the virtual device representation as the physical device moves. The display shows the current position, orientation, and trajectory of the device relative to the target anatomy and ultrasound images. This feedback loop maintains operator flexibility while preventing information loss about spatial relationships.
Solution Approach 2:
The system merges multiple information sources including ultrasound images, 3D anatomical models, and real-time device position data into a single integrated virtual display. This combination presents comprehensive spatial relationship information in one view, allowing operators to maintain manual control while having all relevant spatial information readily available.
Data Source
AI summary
A system and method for providing image guidance for placement of one or more medical devices at a target location. The system can be used to determine one or more affected regions corresponding to the operation of one or more medical devices and display at least a portion of the one or more affected regions. The affected regions can correspond to predicted affected regions and/or dynamic affected regions and can be based at least in part on a variance parameter of the medical device.
