Abstract:
1. A three-dimensional ultrasonic inspection apparatus comprising: an ultrasonic transducer in which a plurality of piezoelectric vibrators are disposed in a matrix or an array; a driving element selecting device to sequentially select piezoelectric vibrators from the plurality of piezoelectric vibrators disposed in the ultrasonic transducer to produce an ultrasonic wave; a signal detecting device to cause the ultrasonic wave generated by the piezoelectric vibrator selected by the driving element selecting device to propagate through an acoustic wave propagating medium and enter a joined area of an object to be inspected for receiving a reflected echo from the joined area, and to detect an electric signal corresponding to the reflected echo from the joined area; a signal processing device to subject the electric signal detected by the signal detecting device to signal processing, and to generate three-dimensional imaging data by causing the electric signal to correspond to a mesh element partitioned in a three-dimensional imaging region set inside the object to be inspected; and a display processing device to display a result of processing three-dimensional imaging data generated by the signal processing device, wherein the display processing device includes:
