1. A method for computer tomography, having the following method steps: in order to scan an object with the aid of a conical beam emanating from a focus and the aid of a detector system, having a plurality of rows of detector elements, for detecting the beam, the focus is moved on a focal path about a system axis without relative movement between the object and the focus in the direction of the system axis, the detector system supplying measured data corresponding to the received radiation, and the length of the focal path being at least equal to the length of a partial revolution interval whose length suffices for the complete reconstruction of a CT image, raw images whose image planes are inclined relative to a central plane containing the focal path are calculated from measured data originating from a partial revolution interval, and a plurality of raw images are combined to form a resulting CT image.
