Method using ultrasound for the non-destructive examination of a test body

Abstract From the Canadian patent

The invention relates to a method for the non-destructive examination of a test body by means of ultrasound, whereby ultrasound waves are injected into the test body by means of one or more ultrasound transducers and ultrasound waves reflected inside the test body are received by a plurality of ultrasound transducers and are converted to ultrasound signals. The ultrasound signals are detected in individual measurement intervals and are stored individually and are accessible to offline evaluation after termination of the measurements. The inventive method allows to subsequently synthesize any acoustic irradiation angle and focusing in the physically possible volume range of the test …
