摘要：The invention relates to a method for recording x-ray images with a C-arm system, which comprises an image recording system rotatable about a center of rotation in a recording plane, a number of x-ray fluoroscopic images of an area of interest of an object lying on an object supporting device are recorded at a plurality of angles of rotations by the image recording system, from which one or more cross-sectional images or a three dimensional can be reconstructed. The method is characterized in that the object supporting device is guided synchronously and in a non-colliding manner with the rotation of the image recording system, such that at every angle of rotation at which the recording of an image takes place, the area of interest of the object lies within a beam cone of the x-ray radiation beam of the image recording system.
