Method and device for improving the image quality during image determination by iterative reconstruction

摘要

Method for improving the image quality in an image determination by iterative reconstruction, in which a section (41) of a path (40) that passes through the focus of the x-ray source (8) when taking a projection is determined, - a plurality of different projections for it Section (41) is calculated, and- an averaging of the plurality of projections for a comparison of the averaged projection is performed with a recorded projection.
