1. A model ablation region determining apparatus for predetermining model ablation regions decoupled from the determination of a desired at least one ablated object region of an object of interest to allow an ablation planning apparatus to determine the desired at least one ablated object region within a few seconds, comprising: a memory; a computer processor; and model ablation region program code, stored in the memory, and configured when executed on the computer processor to: determine the model ablation regions depending on determinations of energy distribution and a spatial relationship between a model ablation element and at least one model energy influencing element by solving linear or non-linear equations indicative of material properties of the object of interest and of the object of interest environment, wherein an model ablation region defines a region in which the determined energy distribution exceeds a threshold, which would be ablated when used in an ablation procedure given the respective spatial relationship between the model ablation element and the at least one model energy influencing element; and store the determined model ablation regions in a model ablation region storing unit such that the ablation planning apparatus can retrieve a stored model ablation region to determine the desired ablated object region within a few seconds.
