8 Claims

1. A system for improving regional resolution in fast anatomical mapping, comprising:

a processor, which is configured to:

receive, on a surface of an anatomical map of a patient organ having a first presentation, a selection of a first selected region, which is intended to have a second presentation different from the first presentation, wherein the anatomical map comprises a mesh of polygons;

identify (i) a perimeter of the first selected region comprising one or more selected areas, and (ii) at least an unselected area positioned within the first selected region; and

identify, within the first selected region, at least an isolated unselected area surrounded by the one or more selected areas;

select unselected polygons within the isolated unselected area;

produce a second selected region, comprising (i) the first selected region, and (ii) the isolated unselected area; and

an output device, which is configured to display the anatomical map having the second presentation applied to the second selected region.
