Abstract:
1. A method for reconstructing a three-dimensional image volume of a region of interest of a patient, comprising: recording a plurality of individual two-dimensional projection images of the region of interest during a rotation of a recording system comprising an x-ray source and an x-ray detector with a constant relative position between a focal point of the x-ray source and the region of interest, the recording system being rotated about a first rotation center between the radiation source and the x-ray detector and simultaneously about a second rotation center in the focal point of the x-ray source; combining the individual two-dimensional projection images to produce a plurality of extend two-dimensional projection images of the region of interest by a control and computing unit; and reconstructing the three-dimensional image volume of the region of interest from the extend two-dimensional projection images with a reduced artifact by the control and computing unit for medically examining the patient.
