Abstract

The invention relates to a gantry 1 for housing an X-ray source 4, with an axis of rotation, with a transmission detector 2 which extends along the inner surface of the gantry 1, and with a spatially resolving coherent scatter detector 3 which is arranged laterally in the direction of the axis of rotation alongside the transmission detector 2. According to the invention it is provided that the coherent scatter detector 3 has a smaller longitudinal extension in the direction of the arc of the gantry 1 and is movable parallel to the plane of the gantry 1 independently of the rotation of the gantry 1. The invention also relates to a method of examining an item for examination 7 by means of X-radiation for striking features using an X-ray tomograph according to the invention with the following steps: recording and examining of the whole item for examination 7 by means of the transmission X-ray image obtained in the transmission detector 2; determining an ROI 8 in which striking features have been recognized in the transmission X-ray image; moving the coherent scatter detector 3 so that its centre 12 lies on a straight line with the centre of the ROI 8 and the X-ray source 4 in a projection perpendicular to the axis of rotation of the gantry 1; examining the ROI 8 by means of the diffraction profiles obtained in the coherent scatter detector 3.
