ABSTRACT:
The present invention relates to a method and a device for recording X-ray images by means of a robotically controlled C-arm system which includes an image recording system (9, 10) that can be rotated in a recording plane around a turning center (17) by means of a C-arm (7) and with which, through rotating of the C-arm (7), a plurality of radioscopic images of a region (14) of interest in an object (13) positioned on an object positioning facility (15) are recorded at different rotation angles, from which images one or more cross-sectional images or a three-dimensional image of a region (14) in the object can be reconstructed. With the method, the C-arm (7) is compliantly repositioned in a collision-free manner in synchronism with the rotation such that the region (14) of interest in an object will, at least at each rotation angle at which image recording takes place, be located within a cone beam (16) of an X-ray bundle of the image recording system (9, 10). The method and associated robotically controlled recording device thus enable the three-dimensional image reconstruction also of regions located at the edge of the object's longitudinal center line.
