ABSTRACT:
An ultrasonic probe for use in an ultrasonic diagnosis device is disclosed. The ultrasonic probe of this invention comprises an oscillator unit having: a first rotatable composite oscillator which includes oscillators having inherent center frequencies different from each other, the oscillators being disposed back-to-back; and a second rotatable, frame-shaped composite oscillator which is disposed around the first composite oscillator and includes oscillators having inherent center frequencies different from each other, the oscillators being disposed back-to-back. The rotating shafts of the first and second composite oscillators are disposed concentrically in such a manner as to be freely brought into and out of mutual engagement. The oscillator unit is disposed together with an acoustic propagation liquid within an acoustic window, and circuitry for driving and controlling the respective oscillators or the oscillator unit are disposed within the box of the ultrasonic probe.
