CT imaging method for periodically moving organs, especially the heart, using 3D filtered back projection, wherein spatial and temporal weighting functions are used to improve image quality

摘要

CT imaging method in which the back projections obtained for sectional imaging purposes are weighted with a first weighting function that is representative of the spatial distance between an observation beam and an observed voxel and a second weighting function that is representative of the temporal movement state of the examination area. an Independent claim is included for a corresponding CT imaging instrument.
