An embodiment of the present invention relates to a method for controlling high-intensity focused ultrasound by using a frequency change, and a high-intensity focused ultrasound treatment device for same. An embodiment of the present invention relates to a high-intensity focused ultrasound treatment device including: an ultrasound generating unit for transmitting high-intensity ultrasound to a specific region of a target a transceiving unit for transmitting ultrasound for diagnosis to the target, and receiving an ultrasound echo signal reflected from the target in order to form a reception signal a storage unit for storing the reception signal and a control unit for confirming whether a temperature change at the specific region in the target is detected on the basis of the reception signal, determining whether the changed temperature reaches a predetermined target temperature if the temperature change is detected on the basis of a confirmation result, and controlling the ultrasound generating unit to stop transmitting the high-intensity ultrasound on the basis of a determination result. According to an embodiment of the present invention, by measuring a temperature of a tissue corresponding to a specific region of a target at high speed during a high-intensity focused ultrasound treatment, the position and degree of a surgical procedure may be confirmed in order to make the surgical procedure accurate.Selon un mode de réalisation, la présente invention concerne un procédé de commande dultrasons focalisés de haute intensité, à laide dun changement de fréquence, et un dispositif de traitement par ultrasons focalisés de haute intensité correspondant. Un mode de réalisation de la présente invention porte sur un dispositif de traitement par ultrasons focalisés de haut intensité comprenant : une unité de génération dultrasons pour émettre des ultrasons de haute intensité vers une région précise dune cible une unité démission-réception pour émettre des ultrasons de diagno
