Abstract
An ultrasonic probe issues an ultrasonic wave to an object, receives a reflected wave from an object, and is provided with multiple piezoelectric elements. A three-dimensional display section displays three-dimensional flaw detection data superimposed on three-dimensional shape data of an object. The computer acquires a reflected ultrasonic wave signal from a reference object (reference). Based on the acquired signal, the computer corrects a reflected ultrasonic wave signal acquired from another object having the same material and shape as the reference. The computer allows the three-dimensional display section to display three-dimensional flaw detection data generated from a reflected ultrasonic wave signal resulting from a difference between a reference and an object.
