A method is for taking computed tomography scans with the aid of a CT unit and to a CT unit. An X-ray tube is moved in a circle or spiral about a z-axis in combination with a detector situated opposite and an object is scanned. The X-ray tube includes a jumping focus with two or more different jumping focal positions relative to the X-ray tube. Parallel data records are formed from the detector data obtained, and tomograms are reconstructed therefrom. When forming the parallel data records, account is taken of the different position of the respectively current jumping focus in relation to the X-ray tube (=jumping focal position) in the radial direction.
