ABSTRACT:
According to the present invention, a cursor is displayed on a screen of display of an ultrasonic image obtained by scanning the surface of an inspection object by use of a probe formed by arrangement of array elements and, further, the cursor is moved to a desired position of the ultrasonic image so that ultrasonic waves are emitted to a position of the surface of the object corresponding to the aforementioned position and the reflection wave signals are displayed in another display portion. Accordingly, not only ultrasonic flaw detection (C-scope) in a plane of the object can be conducted, but also ultrasonic flaw detection (B-scope) in the direction of depth in a desired position of the object can be conducted simultaneously. Consequently, detailed flaw information, such as a flaw type, a flaw position, a flaw size and a flaw shape, in the object can be detected quickly.
