Abstract
Methods and apparatus are provided for reducing image artifacts from a computed tomography (CT) image generated using a CT system. A plurality of projection views of an object are obtained and a plane of reconstruction including reconstructed images is defined. A smoothing function is applied to the reconstructed images to reduce image artifacts wherein a greater amount of z-smoothing is applied to images located a greater distance from an iso-center.
