1. A method, comprising:
receiving a position signal indicating a current position of two or more sensors distributed about a tip section of a catheter within an anatomical structure of a patient;
receiving at least one therapy delivery signal, wherein the at least one therapy delivery signal includes information related to therapy delivered to a region of the anatomical structure;
receiving at least one sensor signal from each of the two or more sensors;
based, at least in part, on the received at least one therapy delivery signal and the received sensor signals,
determining a weighting of one or more sensors of the two or more sensors that indicate therapy delivery, and/or
determining a subset of the two or more sensors that indicate therapy delivery;
based, at least in part, on the received position signal, the received at least one therapy delivery signal, and the determined weighting and/or subset, determining a location of at least one sensor of the two or more sensors;
generating visual indicia based, at least in part, on the determined location of the at least one sensor of the two or more sensors; and
selectively displaying the visual indicia on a graphical user interface based, at least in part, on the determined location of the at least one sensor of the two or more sensors.
