Abstract
An x-ray CT system includes an array of detector elements which measure the attenuation values of a fan beam. Each detector element is comprised of a set of sub-elements disposed in the slice thickness direction. Attenuation signals from the sub-elements are separately preprocessed and summed together to measure the selected slice thickness and avoid partial volume artifacts in the reconstructed image.
