摘要： An ultrasonic probe issues an ultrasonic wave to an object, receives a reflected wave froman 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 obj ect. 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 obj ect 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.

摘要： An ultrasonic inspection device and an ultrasonic inspection method, which allow position adjustment of three-dimensional inspection data and three-dimensional shape data to be easily performed on a display screen and allow a defect echo and a shape echo to be quickly identified.
A calculator generates the three-dimensional inspection data from waveforms stored in a data storage unit. A three-dimensional display unit displays the three-dimensional inspection data generated by the calculator and the three-dimensional shape data on an object to be inspected. The calculator corrects the relative displayed positions of the three-dimensional inspection data and the three-dimensional shape data on the basis of a coordinate system defined by points and a surface that constitute a part of the three-dimensional shape data displayed by the three-dimensional display unit, and causes the three-dimensional display unit to display the three-dimensional inspection data and the three-dimensional shape data while the three-dimensional inspection data and the three-dimensional shape data overlap each other.
