Abstract
The present invention relates to a C-arm X-ray imaging system. In order to provide C-arm systems with an extended three-dimensional field of view, a C-arm X-ray imaging system (), provided to acquire extended three-dimensional images of an object, is provided, comprising a C-arm structure () with an X-ray source () and an X-ray detector () mounted across from the X-ray source, a motorized drive () for a rotational movement of the C-arm structure, and a control unit (). The C-arm structure is provided to perform a rotational scan around an axis of rotation and around an ISO-center acquiring a number of X-ray projections in order to generate image data for a reconstructed three-dimensional field of view. The control unit is configured to control the motorized drive, and to cause the rotational movement of the C-arm structure to perform a first rotational X-ray scan () around a first ISO-center () with a first axis of rotation for a first field of view, and to perform at least a second rotational X-ray scan () around a second ISO-center () with a second axis of rotation for a second field of view. The first and the second center of rotation are displaced in relation to each other such that a connection line between the first and the second ISO-center is arranged transverse to the first and the second axis of rotation.
