Abstract:
1. A method for generating a volume dataset of a subject comprising the steps of: mounting a first X-ray system comprising a first x-ray source and a first X-ray receiver, on a first C-arm; mounting a second X-ray system, comprising a second X-ray source and a second X-ray receiver on a second C-arm: acquiring a first series of 2D projections in a plane of a subject using a said first X-ray system by irradiating the subject with X-rays emitted by said X-ray source from a plurality of different projection angles while rotating said first C-arm around an axis and sweeping a first angular range of substantially X° through Y°; substantially simultaneously with acquiring said first series of 2D projections, acquiring a second series of 2D projections in said plane of the subject using said second X-ray system by irradiating the subject with X-rays emitted by said second X-ray source at a plurality of different projection angles while rotating said second C-arm around an axis and sweeping a second angular range of substantially U° through V° differing from said first angular range; and combining said first series of 2D projections and said second series of 2D projections to generate a volume dataset of the subject.
