High-intensity-low intensity focused ultrasound treatment apparatus according to the present invention, a plurality of ultrasound output unit; And a control unit for controlling the center frequency and intensity of the focused ultrasound output from the ultrasound output unit, and each of the ultrasound output units outputs a low-intensity focused ultrasound to detect lesions. 1 ultrasonic output unit; And a second ultrasound output unit outputting a high-intensity focused ultrasound to remove the detected lesion. The low intensity focused ultrasound output from the first ultrasound output unit is used to detect lesions of the brain by stimulating the patient's brain and simultaneously examining the response, and the high intensity focused ultrasound output from the second ultrasound output unit is It can be used to remove the lesion by applying a thermal or mechanical stimulus to the detected lesion. According to this, since the position of the lesion can be located and removed immediately in real time, it is possible to minimize damage to a functionally important tissue that is more accurate and does not require incision than the conventional technique.
