1. A planning apparatus for determining an ablation probe parameter describing an operation of an ablation probe during an ablation procedure for ablating a part of a subject, the planning apparatus comprising:
a computer; and
a non-transitory computer readable medium having stored thereon a planning computer program comprising program code that, when executed, cause the computer to:
provide a first thermal energy function defining a relation between a first thermal energy distribution to be calculated and a spatial temperature distribution and to provide a temperature-based condition being indicative of a desired treatment outcome for the subject including an ablation of the part of the subject,
determine the first thermal energy distribution by using the first thermal energy function such that the temperature-based condition is fulfilled, the first thermal energy distribution being independent of a type of ablation procedure to be used for ablating the part of the subject,
provide, prior to ablating the part of the subject, a second thermal energy function providing a relation between a) a second thermal energy distribution to be calculated and to be caused by the ablation probe and b) the ablation probe parameter,
determine, prior to ablating the part of the subject, the ablation probe parameter by using the second thermal energy function such that a deviation between the first thermal energy distribution and the second thermal energy distribution fulfills a predefined deviation criterion, and
output the ablation probe parameter to an ablation controller; and
control the ablation controller to output power to the ablation probe in accordance with the ablation probe parameter and ablate the part of the subject without damaging a structure at risk.
