Ablation size estimation and visual representation
A system for visually representing estimated ablation size is provided which includes sensors that acquire location signals indicating locations of an ablation device during an ablation of an organ and ablation parameters signals indicating ablation parameters during the ablation. The system also includes memory which stores location data and ablation parameter data corresponding to the location signals and ablation parameters signals. The system also includes a processing device which generates mapping information for displaying a map of the organ and first object information for displaying a first geometrical object having a first size which represents an estimated depth of the ablation of the organ. The processing device also generates second object information for displaying, concurrently with the first geometrical object, a second geometrical object having a second size which represents an estimated width of the ablation of the organ.
