摘要
The invention relates to a method for evaluating projection datasets of an object undergoing examination. Each projection dataset is assigned a swiveling angle and a recording instant. Each data element of each projection dataset defines a projection line along which an X-ray beam has traveled from an X-ray source to an X-ray detector. The projection datasets form recording groups each of which corresponds with the projection datasets that were recorded during a single swiveling action. A computer determines reconstruction datasets using the projection datasets. Each reconstruction dataset contains at least one reconstruction data value assigned to a reconstruction line. Using a temporal interpolation, the computer determines the reconstruction datasets in such a way that they refer to a uniform reconstruction time. The computer determines a reconstruction of the object undergoing examination using the reconstruction datasets.
