Abstract: The present invention relates to providing X-ray image data of an object. In order to provide a medical X-ray imaging system with improved practicability, a medical X-ray imaging system (100) is provided, comprising at least one X-ray detector (110), an X-ray source arrangement (120), and a patient table (130). The patient table is configured to receive an object for imaging a region of interest (140) 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 is configured to provide X-ray radiation to the region of interest from a number of positions (150) forming a concave open trajectory (160), wherein a middle portion (170) of the trajectory is located below the patient table; and wherein two end regions (180) of the trajectory are extending on the two lateral sides of the table and above the table. The positions are provided by a physical trajectory support structure (190).
