1. A method for performing ablation simulation or performance, or ablation planning and ablation simulation or performance, using an image processing apparatus having one or more processors, the method comprising:
visualizing or displaying, via the one or more processors, at least one image;
automatically identifying, by the one or more processors, at least one treating zone or target shown in the at least one image such that: (i) the one or more processors calculate and determine the at least one treating zone or target shown in the at least one image, or (ii) the one or more processors determine the at least one treating zone or target shown in the at least one image by processing and analyzing the at least one image;
determining or calculating, via the one or more processors, a medial axis or a center line of the at least one treating zone or target;
visualizing or displaying, on a display via the one or more processors, the determined or calculated medial axis or the determined or calculated center line and the at least one treating zone or target being superimposed on or displayed in the at least one image, the determined or calculated medial axis or the determined or calculated center line defining a plurality of target point candidates;
receiving an input, based on or using the superimposed or displayed medial axis or center line on the display via the one or more processors, the input operating to select, designate, or define at least one target point of the plurality of target point candidates to be at least one position on the determined or calculated medial axis or on the determined or calculated center line;
defining, via the one or more processors, the at least one target point of the plurality of target point candidates of the at least one treating zone or target based on the received input, at least one entry point, and a trajectory between the at least one target point and the at least one entry point, the at least one target point of the at least one treating zone or target being defined located or positioned on the determined or calculated medial axis or the determined or calculated center line of the at least one treating zone or target;
corresponding or associating, via the one or more processors, the at least one entry point in the at least one image to at least one entry point for a body of a patient; and
performing the ablation simulation or performance, or the ablation planning and ablation simulation or performance, on the at least one treating zone or target based on the at least one target point such that ablation is simulated with a needle located at or on the target point or ablation is activated with the needle located at or on the target point, the at least one target point operating to define and position a simulation or performance zone, or a planning and simulation or performance zone, to be used to perform the ablation simulation or performance, or the ablation planning and the ablation simulation or performance, on the at least one treating zone or target.
