14. A method for assisting a user in positioning a thermal ablation device in treatment region of a patient body on the basis of a planned ablation position specified in a treatment plan, the thermal ablation device delivering a thermal dose to the treatment region in operation, the method comprising:
determining a current position of the thermal ablation device within the patient body,
determining an optimized thermal dose distribution deliverable to the treatment region by means of the thermal ablation device localized at the current position,
computing a path for steering the thermal ablation device from the current position to the planned position and assigning a cost to the path, the cost quantifying estimated detrimental effects of steering the thermal ablation device along the path, and
presenting information about the optimized thermal dose distribution and about the cost assigned to the determined path to the user for determining, while the thermal ablation device is inserted within the patient body, whether an ablation treatment shall be performed at the current position or the planned ablation position.
