Abstract
The invention relates to a method for generating a 3D reconstruction of an especially large body that cannot be captured by a single projection by capturing at least two projections, which together capture the body, at each of the positions taken up by a C-arm X-ray unit. Data from the two projections is projected onto a virtual detector and the data from the virtual detector is then used for the filtered back projection procedure. It is assumed here that the real source remains motionless and that only the detector moves. A virtual detector D'/D′ is only used in order to carry out large scale filtering in the event that real sources Qand Qfor the two projections do not coincide. A return is then made to two independent projections. These two independent projections are used separately in the filtered back projection procedure to generate the 3D reconstruction.
