A method for the reconstruction of ct-image data, including with weighted backprojection processing unit and ct system for this method

摘要

The present invention relates to a method, a computer unit and a ct system for the reconstruction of ct-image data, which consists of a plurality of image voxels (v_{x, y, z}) , by a weighted filtered backward projection, wherein for the weighting of the projection data (p_conv) in the case of the filtered backprojection a weighting function (w ˜ (q)) is used, which the projection data (p_conv) of the central rays of a detector line, close to the edge lines . weighted less and the projection data of the central rays of a detector line, weighted more central.
