Patent ID: 8094910

Claim:
Method of reconstructing an image function on the basis of a plurality of projection profiles corresponding to a number of projection directions through a region of investigation, wherein each projection profile being measured with a detector device having a plurality of detector elements and including a series of value positions the number of which being equal to the number of detector elements, measured projection values corresponding to projection lines parallel to the respective projection direction are assigned to associated value positions and the number of projection directions is smaller than the number of detector elements and a plurality of remaining value positions are empty, the method comprising the steps of: assigning first interpolation values to the empty value positions for constructing a plurality of interpolation profiles on the basis of the projection profiles, wherein the first interpolation values are obtained from a first interpolation within a group of measured projection values having the same value position in different projection profiles, and determining the image function by applying a predetermined reconstruction algorithm on the interpolation profiles.
