Patent ID: 7780598

Claim:
A sonodynamic treatment apparatus comprising: a first ultrasound radiating unit for radiating a diagnostic ultrasound; a second ultrasound radiating unit for radiating a treatment ultrasound; an echo detection unit for detecting an ultrasound echo corresponding the diagnostic ultrasound; a diagnostic controller for radiating the diagnostic ultrasound with the first ultrasound radiating unit and detecting the ultrasound echo; an echographic controller for processing an echographic image on the basis of the detected ultrasound echo; a treatment controller for radiating the treatment ultrasound with the second ultrasound radiating unit; and an echographic analyzer for detecting a bubble generated on the echographic image in response to radiation of the treatment ultrasound, wherein the treatment controller comprises a pulse generator for controlling radiation of the treatment ultrasound with the second ultrasound radiating unit to have a predetermined exposure duration and a predetermined pause duration of the treatment ultrasound, and an amplifier that decreases an acoustic intensity of the treatment ultrasound radiated by the second ultrasound radiating unit when the bubble is detected and increases the acoustic intensity of the treatment ultrasound radiated by the second ultrasound radiating unit when the bubble is not detected, and wherein the echographic controller processes the echographic image on the basis of the ultrasound echo during the pause duration of the treatment ultrasound.
