Abstract
A computed tomography method and system for performing dynamic scans of objects undergoing cyclic displacement, for example a human heart. Characteristic curves are generated from images reconstructed from projection data synchronized with the cyclic displacement of the object. Each image reflects one displacement cycle of the object, and consists of projection data collected, in one case, within a phase window centered on a specified phase of cyclic displacement of the object, and in another case, consists of projection data collected between two specified phases of cyclic displacement.
