A medical imaging system for providing X-ray image data of an object including at least one X-ray detector, an X-ray source arrangement, and a patient configured to receive an object for imaging a region of interest of the object. The at least one X-ray detector is movably mounted above the patient table; and the at least one X-ray detector and the X-ray source arrangement are movable independently. The X-ray source arrangement includes a physical trajectory support structure and is configured to provide X-ray radiation to the region of interest from a number of positions forming a concave open trajectory, wherein a portion of the trajectory and/or the physical trajectory support structure is located below the patient table; and wherein two end regions of the trajectory are extending on the two lateral sides of above the table.

Providing X-ray image data of an object

The invention relates to an imaging apparatus for imaging an object () being preferentially a catheter. A kinematics model () of a robot representing the object (), which is defined by kinematics parameters, and projection data of the object (), which correspond to different projection directions, are provided. The kinematics model () is modified by modifying the kinematics parameters such that a difference between simulated projection data, which are determined by simulating a forward projection of the kinematics model (), and the provided projection data is minimized. Since the object () is represented by a kinematics model () of a robot, movements of the object (), in particular, deformations of the object (), can be described in a simple way by few kinematics parameters, thereby allowing modifying the model () and, thus, following a movement of the object fast by modifying the few kinematics parameters, in particular, in real-time.
