A medical apparatus (300, 400, 500, 600, 700) comprises a heating system (304) for heating a target zone (324) of a subject (320), wherein the energy density in a predefined volume is modeled (338) using a thermal model and a processor (330) for controlling (340) the heating system (304). The medical apparatus (300, 400, 500, 600, 700) further comprises a memory (336) containing machine executable instructions, wherein execution of the instructions causes the processor (330) to receive (100, 200, 342) a treatment plan, wherein execution of the instructions further causes the processor (330) to repeatedly: heat (102, 202, 344) the target zone (324) during alternating heating periods and cooling periods bycontrolling (340) the heating system (304) using the treatment plan and calculate (104, 204, 346) a present energy density map (350) in a predefined volume using the treatment plan and a thermo acoustic model, wherein the present energy density is repeatedly updated (348)during the heating of the target zone (324). |
