Grid Localization System for MRI Biopsy Targeting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional MRI-guided biopsy procedures are slow and prone to human error due to manual transcription and confirmation of anatomical site coordinates, which increases procedural time and risk of incorrect sampling.
Innovation Solution
A grid localization system (GLS) with indicators and a processor that automates the identification of anatomical site coordinates, allowing for direct data transmission and reducing the need for manual confirmation, coupled with an automated access device (AAD) for precise targeting and sampling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual transcription and confirmation of anatomical site coordinates is used, then human verification is possible, but procedural time increases and human error risk increases
Solution Approach 1:
The patent replaces manual transcription and verification processes with an automated computer-based system. The processor automatically receives anatomical site coordinates from imaging data, determines the corresponding grid location, and activates indicators without requiring manual intervention, thereby eliminating human error while reducing procedural time
Solution Approach 2:
The system performs self-verification by automatically comparing imaging data coordinates with grid coordinates and independently determining the correct access region. The processor autonomously identifies and highlights the target location without requiring external verification, making the system self-sufficient and error-free
2Loss of information
If manual transcription of coordinates is performed, then data can be transferred, but the process is slow and prone to error
Solution Approach 1:
The patent replaces manual coordinate transcription with automated digital data transfer. The processor automatically extracts coordinates from imaging data and transmits them to the grid localization system, eliminating transcription errors and significantly increasing the speed of information transfer
Solution Approach 2:
The system creates a digital copy of the anatomical site coordinates from imaging data and automatically replicates this information on the grid indicators. This digital copying process eliminates manual transcription and ensures accurate, error-free data transfer at high speed
3Manufacturing precision
If automated access device is used, then sampling precision is improved, but device complexity increases
Solution Approach 1:
The patent replaces manual needle insertion with an automated access device that uses robotic or motorized positioning. The processor controls the automated device to precisely reach the anatomical site based on coordinate data, improving access precision while the automation handles the complexity
