Abstract

A method and system for presenting information representative of lesion formation is provided. The system comprises an electronic control unit (ECU). The ECU is configured to acquire a value for an ablation description parameter and/or a position signal metric, wherein the value corresponds to a location in the tissue. The ECU is further configured to evaluate the value, assign it a visual indicator of a visualization scheme associated with the parameter/metric corresponding to the value, and generate a marker comprising the visual indicator such that the marker is indicative of the acquired value. The method comprises acquiring a value for the parameter/metric, and evaluating the value. The method further includes assigning a visual indicator of a visualization scheme associated with the parameter/metric corresponding to the value, and generating a marker comprising the visual indicator.

Claims

1. A system for presenting information representative of lesion formation in tissue during an ablation procedure, comprising:

an electronic control unit (ECU) configured to;

acquire a value for at least one of an ablation description parameter and a position signal metric, the value corresponding to a location in said tissue;

evaluate said value;

assign a visual indicator of a visualization scheme associated with said at least one of said ablation description parameter and said position signal metric to said value in response to the evaluation of said value;

generate a marker responsive to the evaluation of said value and assignment of said visual indicator, said marker comprising said visual indicator such that said marker is indicative of said value of said at least one of said ablation description parameter and said position signal metric.
