Abstract
A three-dimensional ultrasonic inspection apparatuscan make increased inspection accuracy in comparison to the conventional apparatus and includes: an ultrasonic transducerdisposed m×n piezoelectric vibrators in a matrix; a signal processing unitto receive, detect an echo, and generate a three-dimensional image data by processing an electric signal of the echo detected; a peak detecting elementto detect a first peak and a second peak of an intensity distribution of the three-dimensional image data in a depth (z) direction; a joint portion image creation unitto create a three-dimensional image of the joined areaby mapping z direction distance of the first peak and the second peak to x-y plane; a determination unitto determine whether the joined areais sound by two-step determination; and a display unitto display the three-dimensional image and the determination result, of the joined area
