Abstract
A method for reconstructing images from a set of acquired projection views weights the value backprojected into each image voxel depending on whether the backprojected raysum passes through a highly attenuating region in the subject of the image. If the raysum exceeds an attenuation threshold value, the backprojected values are weighted to substantially reduce the contribution of that raysum to the reconstructed image and to thereby reduce streak artifacts otherwise produced by high attenuation objects such as metal surgical clips.
