摘要：
This disclosure generally relates to a method and an apparatus for recording a 3D data set of an ROI (50) complete in the central layer by using a cone-beam C-arm X-ray apparatus (1) having a cone beam (32) with a cone angle (35) in the plane of the C-arm and having a virtual scan center (51) in the center of the ROI (50), wherein the scan is performed with a trajectory pair situated in the virtual scan center (51) and composed of a focus trajectory and a detector trajectory and wherein the rotational portion (402) of the detector trajectory is formed from piece-wise defined superellipses.
