ABSTRACT:
A control device pivots an X-ray arrangement repeatedly between two final angular positions about a pivot axis. Projections of an object arranged in the region of the pivot axis and moving iteratively are detected at a plurality of angular positions and supplied to the control device. The control device also receives a phase position referring to the object and assigns the phase position to each projection. A computer selects one or more projections whose phase position corresponds at least approximately to a reconstruction phase position. If the computer has selected one projection for an angular position, it determines this projection as a reconstruction projection. If the computer has selected a plurality of projections for an angular position, it detects the reconstruction projection using these projections. The computer then detects a three-dimensional reconstruction of the object based on the reconstruction projection.
