Method for Evaluating Treatment-Relevant Spatial Information

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a method and system for evaluating and transferring treatment-relevant spatial anatomical information (such as ablation lines) among three-dimensional (3D) heart data sets, particularly focusing on the left atrium. The core process involves using image registration techniques (like non-rigid mesh registration and coherent point drift algorithms) to align and compare anatomical features from multiple patient scans, allowing treatment planning data to be mapped and analyzed on a common reference model. This enables the assessment of variation in planned treatments, such as ablation lines for atrial fibrillation procedures, and supports improved intervention planning, including the transfer of established planning data to new patient images.

Use CasesContent extracted from patent full text and abstract with AI.

• Assisting clinicians in planning cardiac ablation procedures (e.g., pulmonary vein isolation for atrial fibrillation) by providing average and reference ablation lines based on prior cases.
• Comparing and analyzing variability in treatment plans among different patients to optimize procedural strategies and outcomes.
• Providing automated or semi-automated guidance for planning interventional cardiac treatments using aggregated anatomical and spatial treatment data.
• Facilitating training and education by visualizing mean and variation in ablation lines among patient populations.
• Supporting software platforms that integrate pre-operative imaging data for personalized or standardized treatment planning in electrophysiology labs.

BenefitsContent extracted from patent full text and abstract with AI.

• Enables precise, data-driven planning of complex cardiac interventions, reducing procedural variability and improving safety.
• Facilitates the transfer and adaptation of expert planning to new patient anatomies, streamlining workflow and reducing planning time.
• Provides quantitative evaluation of treatment regions, helping identify safe and effective ablation zones and minimizing risks to critical heart structures.
• Supports the development of automated or AI-assisted treatment planning tools, enhancing consistency and quality of care.
• Improves understanding of anatomical variations and their impact on procedure planning, which can drive best practices and outcomes.

Patent Abstract

The invention relates to a method for evaluating treatment- relevant spatial anatomical information among different data sets of the heart, the method comprising the steps of: - determining a reference anatomical 3 dimensional data set of the heart, - providing a first anatomical 3 dimensional data set of the heart, the first anatomical 3 dimensional data set comprising first treatment-relevant spatial anatomical information, - providing a second anatomical 3 dimensional data set of the heart, the second anatomical 3 dimensional data set comprising second treatment-relevant spatial anatomical information, - registering the reference data set to the first and the second data sets, - transferring the treatment relevant spatial anatomical information of the first and the second data set to the reference data set in order to generate a first transferred treatment-relevant spatial anatomical information on the reference data set and a second transferred treatment- relevant spatial anatomical information on the reference data set - evaluating the first and the second transferred treatment- relevant spatial anatomical information.
