Abstract

In a method for generating a volume dataset of a subject with a first X-ray system having an X-ray source and an X-ray receiver and with a second X-ray system having an X-ray source and an X-ray receiver, the first X-ray system is rotated around an axis and sweeps a first angular range. Substantially simultaneously, a second series of 2D projections of the subject is acquired with the second X-ray system at projection angles differing from one another, by the second X-ray system being rotated around an axis and sweeping a second angular range differing from the first angular range. A volume dataset of the subject is generated from the first and second series of 2D projections of the subject acquired by the two X-ray systems.
