The invention relates to a device for the non-destructive ultrasound testing of a test object, said device comprising: at least one ultrasound transmitter (1, 19) with at least one radiating surface (30) facing the test object for the production of an ultrasound field that at least partially penetrates the test object (3), at least one ultrasound receiver (2) for at least partial detection of the ultrasound field and for conversion to an electric measurement signal, an evaluation unit for the evaluation of the measurement signal in TOFD technology. The device is characterized in that the radiating surface (30) is curved in at least one direction or the radiating surfaces define a surface that is curved in at least one direction. The invention further relates to an associated method.
