IDENTIFYING AN ATTRIBUTE OF AN ELECTROMAGNETIC SOURCE CONFIGURATION BY MATCHING SIMULATED AND PATIENT DATA
First Claim
1. A method performed by a computing system for identifying derived electromagnetic data that matches patient electromagnetic data collected from a patient, the electromagnetic data representing electromagnetic output an electromagnetic source within a body, the method comprising:
- for each of a plurality of model source configurations of the electromagnetic source, accessing a mapping of that model source configuration to derived electromagnetic data that is derived based upon that model source configuration;
accessing a patient source configuration representing a source configuration for the electromagnetic source within the patient;
identifying model source configurations that match the patient source configuration; and
identifying, from the derived electromagnetic data to which the identified model source configurations are mapped, derived electromagnetic data that matches the patient electromagnetic data.

Abstract
Systems are provided for generating data representing electromagnetic states of a heart for medical, scientific, research, and/or engineering purposes. The systems generate the data based on source configurations such as dimensions of, and scar or fibrosis or pro-arrhythmic substrate location within, a heart and a computational model of the electromagnetic output of the heart. The systems may dynamically generate the source configurations to provide representative source configurations that may be found in a population. For each source configuration of the electromagnetic source, the systems run a simulation of the functioning of the heart to generate modeled electromagnetic output (e.g., an electromagnetic mesh for each simulation step with a voltage at each point of the electromagnetic mesh) for that source configuration. The systems may generate a cardiogram for each source configuration from the modeled electromagnetic output of that source configuration for use in predicting the source location of an arrhythmia.
