Patent ID: 7505553

Claim:
A method for taking computed tomography scans with the aid of a CT unit including an X-ray tube movable in at least one of a circle and spiral about a z-axis in combination with a detector situated opposite the X-ray tube, the X-ray tube including a jumping focus with at least two different jumping focal positions relative to the X-ray tube, the method comprising: forming parallel data records from detector data obtained from scanning an object with the X-ray tube, such that the different positions of a respectively current jumping focus in relation to the X-ray tube in a radial direction are taken into account when forming the parallel data records; and reconstructing tomograms from the parallel data records; wherein when compiling the parallel data records, an azimuthal parallel rebinning to identical ray angles θ is carried out separately by jumping focal position and by detector row, the actual radius of the respective jumping focus featured in the calculation of the ray angle θ, and data records being interpolated with the aid of an identical Δθ raster.
