METHOD FOR THE NON-DESTRUCTIVE INSPECTION OF A TEST BODY USING ULTRASOUND

摘要

The invention relates to a method for the non-destructive inspection of a test
body using ultrasound, according to which ultrasonic waves are coupled into
the test body using one or a plurality of ultrasonic transducers and
ultrasonic waves that are reflected inside the test body are received by a
plurality of ultrasonic transducers and converted into ultrasonic signals,
which form the basis of the non-destructive imaging ultrasonic inspection. The
invention is characterised by the following steps: an ultrasonic transducer is
provided and activated on a surface of the test body in such a way that the
ultrasonic waves that have been coupled into the test body are propagated
three-dimensionally inside said body with a largely uniform distribution; the
ultrasonic waves that are reflected inside the test body are received using a
plurality m of ultrasonic transducers that are provided on the surface and m
ultrasonic time signals are generated, in which amplitude information is
contained in a time-dependent manner; the m ultrasonic time signals are
stored; a 3-dimensional volumetric image, a sector image in the form of a 2-
dimensional ultrasonic sectional image through the test body, or an A image in
the form of a 1-dimensional ultrasonic echo signal is reconstructed along a
predefinable introduction angle in a time- and location-dependent manner,
exclusively using at least some of the m ultrasonic time signals.
