The present invention relates to X-ray imaging. In order to provide increased stability for X-ray imaging devices, an X-ray imaging device is provided (10) that comprises an X-ray imaging arrangement (12) with an X-ray source (14) and an X-ray detector (16)； The X-ray imaging device also comprises a support structure (18) that has a base (20) configured to be rotatably attached to a fixed part of a building structure such that the base can be rotated in relation to the fixed part. The support structure also has a C-arm (22) with two opposing ends, at which the X-ray source and the X-ray detector are mounted. The support structure further has a sliding carrier support (24) with which the C-arm is movably mounted to the base. The support structure is movably carrying the X-ray imaging arrangement with a limitation of two degrees of freedom: i) the rotatably attached base provides a first degree of freedom in a first rotational manner (26)； and ii) the sliding carrier support provides a second degree of freedom such that the C-arm can be moved in relation to the sliding carrier support along an arc in a second rotational manner (28). The first rotational manner and the second rotational manner are provided transverse to each other. Further, the first rotational manner is provided around a vertical axis of rotation (30).
