Abstract:
An ultrasound therapy apparatus comprising:a first ultrasound transducer for generating focused ultrasound used in therapeutical purposes; an ultrasound probe arranged in such a manner that said ultrasound probe is moved in combination with said first ultrasound transducer; an intraluminal catheter used to be inserted into a region in the vicinity of an irradiation target region of said focused ultrasound; and imaging means for forming an ultrasound tomographic image in such a manner that while imaging ultrasound is repeatedly transmitted from said ultrasound probe, reflection wave responses are acquired by sequentially scanning reception signals of reflection signals thereof along a lateral direction; wherein: said intraluminal catheter is comprised of: a second ultrasound transducer; and drive means for driving said second ultrasound transducer to generate ultrasound during an imaging operation by said ultrasound imaging means; and also said imaging means superimposes a sound source image which is caused by the ultrasound produced by said second ultrasound transducer on said ultrasound tomographic image.
