Claim Text:
1. A C-arm X-ray imaging system, provided to acquire extended three-dimensional images of an object, the imaging system 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; wherein 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 for generating image data of a reconstructed three-dimensional field of view; the control unit is configured to control the motorized drive; and the control unit is configured to cause the rotational movement of the C-arm structure to perform: the first and the second ISO-center are displaced in relation to each other such that a connection line between the first and the second ISO-centers is arranged transverse to the first and the second axes of rotation; and the control unit is configured to provide a convex as an extended three-dimensional field of view enclosing the first field of view and the second field of view and residual region, which residual regions are located inside the convex hull, but outside the first and second fields of view.
