1. An apparatus for creating a multi-dimensional representation of an object, comprising: an X-ray source for illuminating the object; a sensor located, in relation to the X-ray source, behind the object in a preferential direction defined by the relative positions of the object and of the sensor, for creating a first picture and a second picture of the object; a mover for moving the source or the object so as to change a distance in the preferential direction between the X-ray source and the object between the first and second pictures; a rotator for rotating the preferential direction by a predetermined angle with regard to the object, wherein the rotator is configured to apply two or more different preferential directions differing from each other by an angular increment by moving or displacing the source or the object, wherein a change from a preferential direction to a different preferential direction is so that relatively large changes in perspective are obtained compared to a change in perspective obtained by a single translational motion of the X-ray source performed by the mover; and a combiner configured to determine, from the change in the distance between the first and second pictures, an angle of rotation which describes a rotation of the X-ray source in relation to the object and which corresponds to a change in the perspective from which the object is illuminated and imaged on the sensor; the combiner being further configured to combine the first and second pictures while using the angle of rotation and a computer tomography image processing algorithm in order to acquire the multi-dimensional representation of the object.
