超音波検査方法、超音波検査装置およびプログラム
Document Type and Number:
Japanese Patent JP7433172
Kind Code:
B2
Abstract:
To further reduce the computational load in an inspection process of ultrasonic inspection of an inspection target. An ultrasonic inspection method includes the steps of: collecting data as a result of scanning an inspection target in such a manner that a plurality of probes transmit ultrasonic signals to the inspection target and the probes receive reflected ultrasonic signals from the inspection target; rendering a primary image including a contour and an internal side of the inspection target based on the data as the result of scanning by using a sonic speed of the ultrasonic signals transmitted and received by the probes, the sonic speed being set to a predetermined value regardless of a region through which the ultrasonic signals have passed; and evaluating whether an internal flaw is present in the inspection target in the primary image.
