    摘要： The invention relates to a device for X-ray testing a wheel, which comprises a system (70a, 70b) for conveying said wheel (40) in a transport direction and plane (80) to a test location or test point and for removing said wheel (40) from the test location in said transport direction and plane (80). The present device also comprises a system (170) for handling the wheel (40). Said handling system comprises a system (240a, 240b) for gripping said wheel (40) at said test location, for rotating the wheel (40) about a rotation axis thereof and for swivelling said wheel (40) about a swivelling axis, which substantially extends in said transport plane. An X-ray device (160) having an X-ray emitter (180) and an X-ray detector (190), which define a ray path extending perpendicularly to said swivelling axis, is adapted, such that said ray path can be displaced laterally along a plane, perpendicular to said ray path. Due to the present device, a test process is less expensive.

    摘要： In order to obtain a multidimensional representation of an object, a first and a second image of the object (1) that is illuminated by an x-ray source (4) are generated by means of a sensor (8) which is located in a preferred direction (9) behind the object in relation to the x-ray source, said preferred direction (9) being given by the relative position of the object and the sensor. A distance (10a, 10b) between the x-ray source and the object in the preferred direction differs from the first to the second image. The multidimensional representation of the object is obtained by combining the first and the second image.
