System and method for determining segments for ablation

A non-transitory computer readable medium storing instructions which when executed by at least one processor, cause the at least one processor to non-invasively treat a cardiac arrhythmia in a patient by:

• receiving a plurality of mappings associated with the patient's heart;
• identifying one or more abnormality in the received plurality of mappings associated with the patient's heart;
• providing a two-dimensional (2D) segmented model of the patient's heart for each mapping of the plurality of mappings, each 2D segmented model including a plurality of segments, wherein the plurality of segments is a predetermined number of segments each corresponding to a different portion of the patient's heart;
• determining which segment or segments of the plurality of segments of each of the 2D segmented models include the identified one or more abnormality;
• combining the 2D segmented models;
• generating a three dimensional (3D) segmented model of the combined 2D segmented models including the determined segment or segments of the plurality of segments;
• overlaying the generated 3D segmented model on a 3D image of the patient's heart;
• selecting a target for non-invasive treatment of the cardiac arrhythmia based on the determined segment or segments of the plurality of segments that include the identified one or more abnormality;
• and directing non-invasive therapy at the selected target for ablation.
