Abstract
Imaging guided radiation treatment apparatus and methods are described. A method includes processing a first population of x-ray cone beam projection images to compute therefrom a time sequence of sliding-window tomographic image volumes characterized in that each subsequent member of the time sequence is computed using at least one same x-ray cone beam projection image as used in computing at least one previous member of the time sequence. The method also includes operating an IGRT apparatus to deliver treatment radiation to the target based at least in part on a comparison between at least one of the time sequence of sliding-window tomographic image volumes and a pre-acquired image data set.
