PURPOSE:To irradiate only a necessary point with an ultrasonic wave by providing a fluorescence detecting means to detect a fluorescence generated from a tumor and an ultrasonic generating means to irradiate the tumor with the ultrasonic wave in an ultrasonic wave irradiating part. CONSTITUTION:A photosensitive material such as an HPD is given to a patient, it is integrated in a diseased part, and thereafter, a probe is inserted into a duct cavity. A probe head is positioned in the vicinity predicted as the diseased part, thereafter, water is injected through a feed channel 9 from a pump 12 for water feed, a baloon 10 is expanded, it is sealingly fixed on a duct cavity wall, and the probe head is made stationary. An ultrasonic vibrator 2 is excited, a radial scanning is executed, simultaneously, the ultrasonic wave is made to irradiate the diseased part as a goal, then, the photosensitive material integrated in the diseased part is excited, and the fluorescence is generated. The fluorescence is light-received by a cloth fiber 8, it is light-conducted through a light guide 8b to a light emission detecting.displaying part 16, and a fluorescent quantity is monitored. By detecting the fluorescent quantity in such a way, the position of the diseased part can be correctly grasped, and by irradiating the integrated part of the photosensitive material with the ultrasonic wave, a cellcidal effect can be reinforced, and a correct treatment can be executed. |
