Electrophysiology Mapping onto 3D Heart Geometry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrophysiology mapping systems fail to accurately relate electrophysiology data to pre-existing three-dimensional models of the heart, leading to discrepancies between measurement points and anatomical models during treatment or surgery.
Innovation Solution
A method that maps electrophysiology measurements directly onto previously obtained three-dimensional images of the heart by defining Delaunay edges and triangles, interpolating electrophysiology levels to location points, and optionally assigning colors or grayscale based on these levels, allowing for real-time visualization during procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional electrophysiology mapping systems are used to generate three-dimensional models, then the anatomical structure can be visualized, but the measurement points do not correspond to the model points leading to mapping inaccuracies
Solution Approach 1:
The patent introduces an intermediary coordinate transformation system that maps electrophysiology measurement points to the three-dimensional anatomical model through a common reference coordinate system. This intermediary mapping layer resolves the correspondence problem between measurement points and model points without requiring direct modification of either system.
Solution Approach 2:
The patent transforms the coordinate parameters of measurement points and model points into a unified reference frame, allowing accurate mapping by changing the parameter representation rather than the physical measurement process. This enables precise correspondence through mathematical coordinate transformation.
2Reliability
If pre-existing three-dimensional models are used during treatment, then treatment planning can be performed in advance, but the models are created hours or days before treatment leading to temporal discrepancies
Solution Approach 1:
The patent performs preliminary coordinate system establishment and transformation parameter calculation during the treatment procedure itself, rather than relying solely on pre-treatment modeling. This preliminary setup during treatment ensures temporal consistency while maintaining advance planning benefits.
Solution Approach 2:
The patent implements a dynamic coordinate transformation system that can be updated and adjusted during the treatment procedure, allowing the mapping relationship to adapt to temporal changes in anatomy and measurement conditions, thus maintaining data consistency throughout the procedure.
3Manufacturing precision
If electrophysiology data is mapped to three-dimensional models, then treatment accuracy improves, but the complexity of integrating different data sets increases
Solution Approach 1:
The patent creates a universal coordinate transformation framework that can handle multiple types of data (electrophysiology measurements, anatomical models, imaging data) through a single unified mapping system. This multi-functional approach reduces integration complexity by providing a common interface for diverse data types.
Solution Approach 2:
The patent standardizes the parameter representation of different data sets through coordinate transformation, allowing diverse electrophysiology and anatomical data to be integrated with consistent parameter formats, thereby reducing the complexity of data fusion while maintaining high treatment precision.
