摘要： A sensitizer for tumor treatment has a structure such that a lipophilic group and a hydrophilic group are bound to one and the same carbon atom in a compound containing a xanthene dye structure. It is important that the lipophilic group and hydrophilic group are bound to one and the same carbon atom; if they are separated from each other, no sufficient effect is obtained. Thus, the sensitizer possesses both lipophilicity and hydrophilicity. This sensitizer has a function of promoting acoustic cavitation and a function of revealing an antitumor effect and is an agent highly accumulable in tumor tissues. Thus, this sensitizer is highly selective for tumor tissues and enables the treatment of malignant tumor using ultrasound.

摘要： An ultrasound therapy apparatus delivers focused ultrasound for therapeutical purposes which can be correctly targeted to a target region, and also, a positional shift from the target region under irradiation of ultrasound can be effectively avoided. An ultrasound transducer is inside an applicator with an imaging ultrasonic probe. Another ultrasound transducer monitors a position of a target and a positional shift is inside a catheter which is inserted into a urethral tube. An imaging system drives the ultrasound probe to display an ultrasound tomographic image of a region in the vicinity of a target region. The ultrasound transducer is driven in a pulse-shaped mode at the same frequency as the imaging ultrasound and also at such timing when the imaging ultrasound is reached. As a result, a point-shaped sound source image is superimposed and displayed on an ultrasound tomographic image.

Generated drive phases are applied to drive signal generating circuits, generated drive signals are applied to element drive circuits and a group of fundamental frequency elements and a group of second harmonic elements are driven. The drive phases are controlled such that the fundamental wave and second harmonic wave are superimposed on each other in a medium near a focal point, thus generating acoustic caviation locally and efficiently.
