Abstract: The invention relates to an angiographic x-ray diagnostic device for rotation angiography with an x-ray emitter which can be moved on a circular path about a patient located on a patient support table, with an image detector unit which can moved on the circular path facing the x-ray emitter, with a digital image system for recording a plurality of projection images by means of rotation angiography, with a device for image processing, by means of which the projection images are reconstructed into a 3D volume image, and with a device for correcting physical effects and/or inadequacies in the recording system such as truncation correction, scatter correction, ring artifact correction, correction of the beam hardening and/or of the low frequency drop for the soft tissue display of projection images and the 3D volume images resulting therefrom.

Abstract: A method for performing an exact volume imaging with a C-arm digital x-ray imaging system by moving the source through two partial circular scans which form a complete source trajectory. The partial circular scans form a complete source trajectory when the plane defined by the C-arm is repositioned for the second scan at an angle equal to the cone angle with respect to the long axis of the patient.
