FIELD: medicine.SUBSTANCE: group of inventions relates to medicine, specifically a heating system for heating the target zone using a treatment plan and calculating an energy density map using a thermoacoustic model. Medical apparatus comprises a computer-readable medium, comprising a computer program for performing a method for heating a target zone using a treatment plan and energy density data. Medium contains machine-executable instructions for execution by the processor, controlling the medical apparatus. Medical apparatus comprises: a heating system for heating a target area of a patient, wherein execution of instructions prompts the processor to receive a treatment plan. Execution of instructions further prompts the processor to repeatedly: heat the target area during alternating heating periods and cooling periods by controlling the heating system using the treatment plan. Calculate the current energy density map in a preset volume using a treatment plan and a thermoacoustic model. Furthermore, the current energy density is repeatedly updated during the heating of the target zone. Calculate the cumulative energy density map by summing the repeatedly calculated current energy density maps, taking into account the estimation of the cooling rate of the tissue. Display the cumulative energy density map on a display. Modify the treatment plan in accordance with the cumulative energy density map taking into account the next heating instance.EFFECT: group of inventions allows to limit the maximum cumulative energy density in the target zone.12 cl, 8 dwgГруппа изобретений относиться к медицине, а именно к системе нагревания для нагревания целевой зоны с использованием плана лечения и вычислению карты плотности энергии с использованием термоакустической модели.
