Abstract

A method for the ultrasound check of a test object involves moving a test probe along a test probe surface and sending ultrasound impulses into the test object by the test probe. Respective echo signals corresponding with the emitted ultrasound impulses are received by the test probe. An image of a predetermined test region of the test object is prepared on the basis of an overlapping and averaging of amplitude values of the received echo signals by a data processing unit. The respective position of the test probe when sending the ultrasound signals and/or when receiving the corresponding echo signals is captured by a capturing unit. The respectively captured positions of the test probe are considered when creating the image of the test region of the test object.
