<P>PROBLEM TO BE SOLVED: To provide an ultrasonic irradition device which can drive an ultrasonic vibrator to suppress the generation of standing waves as much as possible and can safely and efficiently perform thrombolytic therapy for a living body, and to provide an ultrasonic vibrator driving method in the ultrasonic irradiation device. <P>SOLUTION: The ultrasonic irradiation device includes: a tabular ultrasonic wave generation part which can be attached to an object to be irradiated with ultrasonic wave; waveform generation parts 30-32 which generate a current waveform that is a current waveform, and a subsequent waveform which has a different phase from the current waveform and should be the next waveform after changeover; a waveform switch part 33 which repeatedly switches the current waveform into the next waveform and output it; and a driving part 35 which drives the ultrasonic wave generation part by an output waveform of the waveform switch part. <P>COPYRIGHT: (C)2013,JPO&INPIT |
