Abstract
The invention relates to a computed tomography method in which a conical radiation beam traverses an examination zone during a helical relative motion between the radiation beam and the examination zone. The reconstruction is performed by means of filtered backprojection, the filtering operations involving measured values resulting from different projections of voxels from at least approximately the same surface within the examination zone.
