SYSTEMS FOR HIGH-RESOLUTION MAPPING OF TISSUE

According to some embodiments, methods and systems of enhancing a map of a targeted anatomical region comprise receiving mapping data from a plurality of mapping electrodes, receiving high-resolution mapping data from a high-resolution roving electrode configured to be moved to locations between the plurality of mapping electrodes, wherein the mapping system is configured to supplement, enhance or refine a map of the targeted anatomical region or to directly create a high-resolution three-dimensional map using the processor receiving the data obtained from the plurality of mapping electrodes and from the high-resolution roving electrode.
