Electrode Array Positioning Using 3D-to-2D Body Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Proper positioning of electrode arrays relative to each other and a target region can be difficult, especially when self-applied, diminishing the independence of the subject and requiring assistance from another person.
Innovation Solution
A method and system for generating an electronic 2-dimensional map from a 3-dimensional map indicating electrode array placement, using fiducials and visible markings on a substrate to facilitate accurate positioning of electrode arrays on a patient's body, allowing for self-application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If electrode arrays are positioned using traditional methods without visual aids, then the placement process is simpler, but positioning accuracy and treatment effectiveness deteriorate
Solution Approach 1:
The patent creates a visual copy (2D map) of the 3D body surface with electrode array positions, allowing patients to accurately transfer positioning information from the digital model to their actual bodies without requiring complex 3D measurement tools or professional assistance
Solution Approach 2:
The patent converts 3D electrode array placement positions on the body surface into a 2D visual map representation, making the positioning information easier to understand and transfer while maintaining spatial relationships through projected geometry
2Measurement precision
If electrode arrays require professional assistance for positioning, then positioning accuracy improves, but patient independence and convenience deteriorate
Solution Approach 1:
The patent enables patients to independently position their own electrode arrays by providing them with a visual 2D map that clearly shows where to place each array on their body, eliminating the need for professional assistance while maintaining positioning accuracy
Solution Approach 2:
The patent pre-calculates and displays the optimal electrode array positions on a 2D map before the patient actually places the arrays, allowing the patient to plan and execute the positioning independently based on the pre-prepared visual guide
3Adaptability or versatility
If larger electrode arrays are used for torso applications, then treatment versatility improves, but positioning difficulty and required assistance increase
Solution Approach 1:
The patent adapts the 3D to 2D mapping approach for different body regions including the torso, allowing larger electrode arrays to be positioned accurately by representing their 3D placement locations on a 2D map that preserves spatial relationships
Solution Approach 2:
The patent creates a universal positioning system that works across different body regions (head, torso, etc.) and different array sizes by using a standardized 2D map representation that can accommodate various treatment configurations
