<p>According to the present invention, a cursor (41) is displayed on a screen of display of a supersonic 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 (41) is moved to a desired position of the supersonic image in a first display portion (40) so that supersonic waves are emitted to a position of the surface of the object (3) corresponding to the aforementioned position and the reflection wave signals are displayed in another display portion (42). Accordingly, not only supersonic flaw detection (C-scope) in a plane of the object can be conducted, but also supersonic 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.</p> |
