Planning apparatus for determining an ablation probe parameter for a single ablation probe or for multiple ablation probes

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 thermal energy determination providing unit configured 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,
• a thermal energy determination unit configured to determine the first thermal energy distribution by using the first thermal energy function such that the temperature-based condition is fulfilled,
• an ablation probe parameter determination providing unit configured to provide 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,
• an ablation probe parameter determination unit configured to determine 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 fulfils a predefined deviation criterion.
