Medical Imaging System for Real-Time Accessory Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During interventional procedures, medical accessories cannot be accurately positioned in real time due to the inability to directly observe internal structures, leading to inefficient and time-consuming adjustments based on multiple scans, relying heavily on operator experience.
Innovation Solution
A medical imaging method and system that determines the position of a medical accessory in a reference coordinate system using a camera image, reconstructs a medical image based on scanning results, and displays the position in real time, simplifying the positioning process and improving accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple scans are performed to confirm the position of the medical accessory, then the positioning accuracy can be improved, but the procedure becomes more complex and time-consuming
Solution Approach 1:
The patent performs preliminary image reconstruction and position determination before the interventional procedure begins. By pre-processing the scanning results to create a three-dimensional medical image model and pre-calculating the position of the medical accessory, the system eliminates the need for multiple iterative scans during the procedure, thereby reducing procedural complexity while maintaining positioning accuracy.
Solution Approach 2:
The patent creates a virtual copy of the medical accessory's position within the three-dimensional medical image model. Instead of repeatedly scanning the actual medical accessory during the procedure, the system uses the pre-reconstructed image data to display and verify the accessory's position, effectively replacing multiple physical scans with a single virtual representation.
2Measurement precision
If multiple scans are performed to adjust the medical accessory position, then the positioning accuracy can be improved, but the time required for the procedure increases
Solution Approach 1:
The system performs all necessary image reconstruction and position calculation actions before the interventional procedure starts. By pre-processing the scanning data to generate the three-dimensional model and pre-determining the medical accessory position, the patent eliminates time-consuming iterative adjustments during the procedure, significantly reducing overall procedure duration while maintaining high positioning accuracy.
Solution Approach 2:
The patent ensures continuous availability of accurate position information by pre-reconstructing the medical image and pre-calculating positions before the procedure. This continuous preparation allows the operator to immediately access accurate positioning data without interruptions for repeated scanning, maintaining continuous useful action throughout the procedure.
3Measurement precision
If the operator adjusts the medical accessory position based on scan results, then the positioning accuracy can be improved, but the reliability decreases due to dependence on operator experience
Solution Approach 1:
The patent replaces the mechanical process of manual position adjustment based on operator experience with an automated image processing system. The three-dimensional medical image model and automated position determination algorithms objectively display the medical accessory's position, eliminating reliance on operator judgment and experience, thereby increasing procedure reliability while maintaining positioning accuracy.
Solution Approach 2:
The system provides objective feedback through the three-dimensional medical image model that clearly displays the medical accessory's position. This visual feedback mechanism gives the operator precise information about the accessory's location without relying on subjective interpretation, enabling more reliable and consistent positioning adjustments.
