Abstract:
In order to regularize a reconstruction method associated with computed tomography (CT), in at least one example embodiment, information relating to the statistics of the attenuation values of the reconstructed object is also included in the form of the logarithmic probability function of the attenuation values. This information can be obtained from the regions of those image parts which are still completely contained in a scanning field of view (SFOV), but nevertheless lie in the vicinity of the region where the object leaves the SFOV. Furthermore, the information may be used in an algebraic reconstruction method by adding a boundary condition term to the cost function to be minimized.
