摘要
A method and system for implementing the method for extending the effective field of view of a CT scanner, comprising the steps of forming a preliminary estimate of the projection mass for each image projection, forming a preliminary estimate of the center of mass for each image projection, estimating the image mass and center of mass from the preliminary projection mass and center of mass projections, and forming a second estimate of the projection mass and center of mass from the image mass and center of mass.
