Abstract: Scatter correction for tomography: for each position, two images are acquired, a first image without and a second image with a scatter reducing aperture plate (50). A scatter image is calculated by subtracting the second image from the first image. The apertures (48) in the scatter reducing plate (50) are arranged hexagonally in order to optimise the packaging density of the apertures.

Abstract: A method for the non-destructive testing of the volume of a test object, during the course of which a volume raw image of the test object is recorded by a suitable non-destructive imaging testing method. Then, those regions of the volume raw image are identified that are not to be attributed to the test object material. It is checked whether an identified region is completely embedded in regions that are to be associated with the test object material. If necessary, such a region is assimilated to those regions that are to be associated with the test object material, forming a filled volume raw image. Finally, a difference is generated between the volume raw image and the filled volume raw image, forming a first flaw image.

Abstract: Systems, methods, and devices for determining relative and absolute positions and orientations of a detector and an inspection part of a CT system. In some cases positions/orientations of the detector and the inspection part can be defined, at least in part, by tilt angles relative to reference axes and/or planes defined by various combinations of the reference axes. In some embodiments, sensors coupled to the detector and to a stage assembly having the inspection part coupled thereto can be used to determine the tilt angles of the inspection part and the detector, respectively. Data from the sensors characterizing tilt angles of the detector and the inspection part can be used to adjust projectional radiographs of the inspection part to correct for the mechanical wobble of the stage. By using tilt data to adjust projectional radiographs, the quality of tomographic images and 3-dimensional reconstructions of the inspection part can be improved.

Abstract: The invention relates to a method for testing of a train wheel by ultrasound. The method is based on a pulsed ultrasonic field in the train wheel to be tested by an array of individually controllable ultrasonic transmitting transducers acoustically coupled to the train wheel each controlled with a specific analog transient excitation signal. Each analog transient excitation signal generated based on an ultrasonic transmitting transducer-specific stored digital transient excitation function. The resulting echo signals from the train wheel to be tested are recorded by an array of individually controllable ultrasonic receiving transducers. Each ultrasonic receiving transducer can provide an analog, time-resolved echo signal. The received echo signals can be digitized in a transducer-specific way and stored in a set. A plurality of different reception processing rules can then be applied to the latter. Furthermore, the invention relates to a device for carrying out the method.

Abstract: Embodiments relate to a method for ultrasonic testing according to the pulse-echo method as well as an arrangement for performing such a method. By means of an ultrasonic transducer, an ultrasonic pulse is obliquely incident into a sound incidence surface of a test object. Next, an echo signal is received from the test object. This takes place either by means of the ultrasonic transducer, which has emitted the ultrasonic pulse or with another ultrasonic transducer. The time amplitude characteristic of the echo signal is evaluated in a predefined defect expectation interval of time. The evaluation step includes, in at least one section of the amplitude characteristic, an amplification of the amplitude and/or a reduction in the threshold value. For example, the amplitude of the received echo signal is then compared with the predefined threshold value.
