1. A medical system, comprising:

  • a carrier disposable in pressure-wave-transmitting contact with a patient;

    at least one electroacoustic transducer attached to said carrier;

    an a-c current generator operatively connected to said transducer for energizing said transducer with an electrical signal of a pre-established ultrasonic frequency to produce a first pressure wave;

    at least one acoustoelectric transducer attached to said carrier; and

    analyzing means operatively connected to said acoustoelectric transducer for determining three-dimensional shapes of internal tissues of the patient by analyzing signals generated by said acoustoelectric transducer in response to second pressure waves produced at internal tissues of the patient in response to said first pressure wave.
