摘要：
Cardiac CT imaging using gated reconstruction is currently limited in its temporal and spatial resolution. According to an exemplary embodiment of the present invention, an examination apparatus is provided in which an identification of a high contrast object is performed. This high contrast object is then followed through the phases, resulting in a motion vector field of the high contrast object, on the basis of which a motion compensated reconstruction is then performed.
