摘要： 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.

摘要： An ultrasonic inspection device allows position adjustment of three-dimensional inspection data and shape data to be easily performed on a display screen and allows 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.

摘要： Ultrasonic inspection equipment facilitates alignment of display positions of three-dimensional ultrasonic inspection data and three-dimensional shape data, and quickly discriminates between a defect echo and an inner-wall echo. A computer 102A has a position correction function of correcting a relative display position between three-dimensional shape data and three-dimensional ultrasonic inspection data. A display position of the three-dimensional ultrasonic inspection data or that of the three-dimensional shape data is moved by a norm of a mean vector along the mean vector that is calculated from a plurality of vectors defined by a plurality of points selected in the three-dimensional ultrasonic inspection data and by a plurality of points selected in the three-dimensional shape data. The three-dimensional shape data and the three-dimensional ultrasonic inspection data are displayed in such a manner as to be superimposed on each other on a three-dimensional display unit 103C.

摘要： In the ultrasonic inspection method and equipment, a high-resolution and high-S/N-ratio inspection image can be speedily acquired with ease-of-operability. Inspection of the inside of the inspection target is performed by changing incident angle of the ultrasonic wave oscillated from the array-probe ultrasonic sensor. Then, while performing the inspection, the array-probe ultrasonic sensor is sequentially displaced from the position to the position via the position by using the displacement member. This displacement allows acquisition of inspection images on each position basis. Finally, the inspection images thus acquired are visualized as a processed image by adding or averaging the inspection images by shifting the images by displacement quantity of the array-probe ultrasonic sensor.
