PURPOSE: An output power control method of an HIFU transducer is provided, which can add antifocus in which the output becomes zero. CONSTITUTION: An output power control method of an HIFU transducer comprises: a step(S110) of calculating each channel output condition of a plurality of elements in order to form focus and antifocus; a step(S120) of recomputing each channel output condition by reflecting the property of the output controlling hardware based on the calculated output condition; a step(S130) of simulating each output sound field of the element based on the recomputed output condition; and a step(S140) of simulating the temperature change according to the output sound device based on the simulated output sound field.
