1. An ultrasonic inspection apparatus comprising:

  • an ultrasonic probe apparatus provided with an ultrasonic transducer constituted of a plurality of piezoelectric vibrators;

    a drive element selecting section that is connected to the plurality of piezoelectric vibrators of the ultrasonic transducer and is adopted to select a required piezoelectric vibrator based on a drive signal from a signal generator;

    a signal detecting circuit that causes an ultrasonic wave emitted from the piezoelectric vibrator selected by the drive element selecting section to be incident via an acoustic propagation medium on an inspection object and receives a reflected echo thereof to detect an electric signal dependent on the reflected echo; and

    a signal processing section that applies a parallel arithmetic process to the detected electric signal dependent on the reflected echo and produces data on an internal image of the inspection object,wherein the ultrasonic probe apparatus includes a display unit that displays an image based on the image data produced by the signal processing section, and an input unit used to input an operation command such as a command to start or terminate an inspection, or to set inspection conditions.
