Using signed distance functions to visualize pulsed field ablation (pfa) tags

Abstract

Disclosed are systems and methods for visualization of pulsed field ablation tags. In some implementations, a system includes a device, comprising a processor in communication with one or more sensors and a catheter comprising a plurality of electrodes. In some implementations, the processor is configured to: receive, via the one or more sensors, a position of each of the plurality of electrodes within a three-dimensional environment during a first ablation session; calculate, for the first ablation session, a first implicit function representing an energy field of the first ablation session from the received positions of each of the plurality of electrodes; and present, via a display, a first volumetric representation of the calculated first implicit function.

Dependencies are inferred from the claim text.
