1. A method, comprising:
generating, by a processor, a projected ablation zone of an ablation probe based on ablation parameters;
displaying, on a display coupled to the processor, a representation of the ablation probe and the projected ablation zone on image data of a patient, the projected ablation zone being displayed with a zone of certainty surrounding a target within the patient and representing a confidence interval associated with a margin of an actual ablation zone resulting from an ablation procedure, the confidence interval being between a lower boundary of the zone of certainty and an upper boundary of the zone of certainty; and
syncing the confidence interval with the ablation procedure on the display to enable visualization of the confidence interval of the actual ablation zone on the image data of the patient while the margin of the actual ablation zone increases in size, wherein the confidence interval is shown on the display during the ablation procedure as a spheroid dynamically and repeatedly oscillating between the lower boundary of the zone of certainty and the upper boundary of the zone of certainty to visually convey uncertainty in the margin of the actual ablation zone.
