Ultrasonic irradiation system

PROBLEM TO BE SOLVED: To provide an ultrasonic wave irradiation system that simply and accurately directs ultrasonic waves. SOLUTION: The ultrasonic wave irradiation system is provided with at least two light sources 2 for performing the spot irradiation of a subject 10 with laser light, a transducer 3 for irradiating the subject with ultrasonic waves, a detector 4 for imaging the laser light irradiation region on the subject, a display 5 for displaying the image information obtained by the detector, an image processor 6 for processing the image information, and a driving device 7 for moving the transducer. The laser light is irradiated so as to mutually crossing on the ultrasonic wave propagation axis passing through the focus of ultrasonic waves. The image processor obtains, from the image information, the interval between the light spots formed on the subject, and controls the driving device from the obtained light spot interval.
