1. Method for the non-destructive inspection of a test object ( 10 ) with a great material thickness by means of ultrasound comprising the following method steps: a. providing an ultrasonic test probe ( b. selecting a first group j (j=1, 2, 3, . . . ) of transducer segments ( c. carrying out an ultrasound inspection of the test object ( characterized in that a predetermined criterion K has to be satisfied when the method is being carried out which is dependent upon the ultrasonic field that is generated by the active surface Fj of the ultrasonic transducer ( selecting the first group j (j=1, 2, 3, . . . ) of transducer segments that are activated in parallel in such a way that the ultrasonic field generated by the active surface Fj of the ultrasonic transducer ( wherein the criterion K is satisfied if: applies, with dj being the minimum distance of the sector Rj to be inspected from the coupling location (
