Abstract

A method for recording a projection dataset of a object to be recorded using a plurality of X-ray sources is provided, which X-ray sources are spaced apart from one another on average by an angle α relative to an isocenter. A plurality of projection images from different recording directions are recorded in succession while activating the corresponding X-ray sources. Two X-ray sources are activated in succession having a spacing of at least 2 α relative to the isocenter.
