1. A method of performing an ablation procedure, comprising:
displaying three-dimensional image data of at least one anatomical feature of a patient;
receiving user input of an ablation target for placing an ablation needle in the at least one anatomical feature of the patient;
determining a position and orientation of the ablation needle based on the user input;
displaying an image of a virtual ablation needle in the three-dimensional image data of the at least one anatomical feature of the patient according to the determined position and orientation of the ablation needle;
receiving user input of parameters of operating the ablation needle;
displaying a three-dimensional representation of a projected ablation zone surrounding the ablation target and surrounding a distal portion of the virtual ablation needle, wherein the representation of the projected ablation zone is generated in response to the received user input of parameters and the determined position and orientation of the ablation needle; and
displaying a three-dimensional representation of a projected temperature gradient extending radially outward from an outer border of the representation of the projected ablation zone, the projected temperature gradient surrounding the representation of the projected ablation zone, the distal portion of the virtual ablation needle, and the ablation target, wherein the representation of the projected temperature gradient demonstrates a projected temperature level of tissue in proximity to the ablation target that would result from operation of the ablation needle according to the received user input of parameters.
