Stair-step artifacts in three-dimensional helical CT: an experimental study.

Abstract

PURPOSE Stair-step artifacts in helical computed tomography (CT) are associated with inclined surfaces in longitudinal sections. The authors investigated the origin and the characteristics of the artifacts. MATERIALS AND METHODS A cone phantom and a skull were dry-scanned with a helical CT scanner, and images were reconstructed by using the half-scan… (More)
