Abstract
An X-ray CT system is disclosed for producing tomographic phase contrast and absorption images. In at least one embodiment, the system includes a gantry, including a stationary stator and a first rotor supported on the stator and rotates relative to the stator about a system axis, at least one X-ray source detector system that can rotate about a patient and a system axis and is arranged on the first rotor, and at least one set of X-ray optical gratings for determining phase contrast. According to at least one embodiment, the at least one set of X-ray optical gratings is arranged such that it can be displaced relative to the first rotor of the gantry.
