Patent ID: 7916827

Claim:
A method for evaluating a plurality of projection datasets of an object under a medical examination, comprising: assigning a plurality of recording instants to the projection datasets at which the projection datasets are recorded by an X-ray detector located diametrically opposite to an X-ray source with reference to a swiveling axis; assigning a plurality of swiveling angles to the projection datasets at which the X-ray source is swiveled with reference to the swiveling axis at the recording instants; determining an end position; terminating swiveling the X-ray source when the end position has been reached; defining a plurality of projection lines for data elements of the projection datasets along which X-ray beams travel from the X-ray source to the X-ray detector; selecting a reconstruction time; determining reconstruction datasets from the projection datasets for the selected reconstruction time so that the reconstruction time is uniform for all the reconstruction datasets; assigning reconstruction lines to reconstruction data values of the reconstruction datasets; determining the reconstruction data values by a temporal interpolation using the data elements whose projection lines correspond with the reconstruction lines and using the recording instants; and reconstructing the object based on the reconstruction data values of the reconstruction datasets having the uniform reconstruction time for medically examining the object.
