The invention is a method using ultrasound for non-destructive examination of a test body, whereby ultrasonic waves are coupled into the test body with one ultrasonic transducer or a multiplicity of ultrasonic transducers and the ultrasonic waves reflected inside the test body are received by a multiplicity of ultrasonic transducers and converted into ultrasonic signals. The ultrasonic signals detected in the single measurement periods are individually stored and are accessible for off-line evaluation after termination of the measurements. Application of corresponding reconstruction algorithms permits subsequent synthetization of any desired ultrasonic coupling-in angles and focussing into the volume region of the test body from the stored ultrasonic signals without requiring any additional ultrasonic measurements.

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

A method for an imaging ultrasonic inspection of a three-dimensional workpiece, in which ultrasonic waves are coupled into the workpiece with at least one ultrasonic transducer and ultrasonic waves reflected within the workpiece are received by ultrasonic transducers and converted into ultrasonic signals forming the basis of the non-destructive imaging ultrasonic inspection.

Method and device for an imaging ultrasonic inspection of a three-dimensional workpiece

A method for the non-destructive inspection of a test body using ultrasound is disclosed, in which at least one ultrasonic transducer couples ultrasonic waves into the test body and ultrasonic waves reflected inside the test body are received by ultrasonic transducers and converted into ultrasonic signals, which form the basis of the non-destructive inspection.
