Abstract
In three-dimensional X-ray imaging, with C-arm systems, scan setup has to be performed manually under fluoroscopic control. According to an exemplary embodiment of the present invention, a scan planning system for planning a data acquisition process is provided, which is adapted to predict a field of view to be reconstructed and an image quality in the field of view with respect to the actual three-dimensional scan parameter set and previously acquired images or other information. The scan planning system may be accomplished by a stand control unit.
