Abstract: The invention relates to a method for non-destructive ultra-sonic testing, in which ultrasonic pulses with a pulse repetition frequency are radiated by means of an ultrasonic transmitter into a workpiece to be tested and the ultrasonic pulses are reflected to bounding surfaces in the workpiece and the reflected ultra sound is recorded by means of an ultra-sonic receiver and the signals are displayed in time- or position-dependent resolution. The method is characterized in that the pulse repetition frequency is changed at least once during the method.

Abstract: The invention relates to a method for the non-destructive ultrasonic testing of a test piece (3) with flat surfaces (5) at an angle to each other by means of several selectively activatable ultrasonic transducers (2, 2?, 2?), whereby the method comprises several test cycles, with which certain (2,2?) of the several ultrasonic transducers (2, 2?,2?) are selected and activated, in order to emit at least one ultrasonic pulse (7, 7?) to the test piece, and with which the ultrasonic pulse reflected in the test piece (3) is received by the selected and/or, if necessary, other ultrasonic transducers (2, 2?, 2?). The method according to the present invention is characterized in that in the respective test cycle, the determined ultrasonic transducers (2, 2?) are so selected and activated, that the main propagation direction (6, 6?) of the ultrasonic pulse (7, 7?) produced by the selected and activated ultrasonic transducers (2, 2?) is perpendicular to at least one of the angled surfaces (5) of the test piece (3).

Abstract: A computed tomography method for determining a volumetric representation of a sample comprises using reconstructed volume data of the sample from x-ray projections of the sample taken by an x-ray system, computing a set of artificial projections of said sample by a forward projection from said reconstructed volume data , and determining, essentially from process data of said reconstruction including said reconstructed volume data and/or said x-ray projections, individual confidence measures for single voxels of said volume data based on calculating, for each of said measured x-ray projections, the difference between the contribution of this measured x-ray projection to the voxel under inspection and the contribution from a corresponding artificial projection to the voxel under inspection.

Abstract: A method for nondestructive testing of a test object by means of ultrasound, and a corresponding device, the method including radiating directed ultrasonic pulses into the test object 100 at an irradiation angle ?, whereby the irradiation angle ? is set electronically, recording of echo signals that result from the ultrasonic pulses radiated into the test object 100, determining an ERS value of an error 102 in the volume of the test object from echo signals, which can be associated with the error 102.

Abstract: A method and system for automated testing and/or measurement of a plurality of substantially identical components by means of X-ray radiation comprises a testing/measuring device with an X-ray device, a protection cabin surrounding the testing/measuring device, a conveying device for continuously conveying components to or away from the testing/measuring device, and a control/evaluation unit, which is set up for automated control of the system and for evaluation of the X-ray signals. The testing/measuring device comprises a support and a rotor mounted on the support so as to be continuously rotatable, the X-ray device being arranged on the rotor and the conveying device being set up for serial conveying of the components through the rotor and the control/evaluation unit for computer tomographic evaluation of the X-ray signals.

Abstract: The invention relates to a method for the non-destructive ultrasound inspection of a high-pressure line as a testing piece by means of the pulse-echo method, where the high-pressure line is conveyed to a near-field range of at least one ultrasonic transducer and an ultrasonic pulse is emitted with a perpendicular sound incidence on the high-pressure line in such a way that the high-pressure line is completely captured in its cross section by the near-field sound emission caused by the ultrasonic transducer, and the reflected ultrasonic pulse(s) is/are received by the ultrasonic transducer and/or, optionally, further ultrasonic transducers, the associated echo delay times are recorded and, optionally, evaluated.
