Half-scan algorithm for use with a high speed multi-row fan beam helical detector

摘要

A method and apparatus for use with a multi-row CT fan beam system for collecting data in a high speed mode and for using data corresponding to half-scans in order to generate images within one or more image planes wherein, for each beam angle corresponding to an image plane data is generated by interpolating and/or extrapolating between simultaneously collected data wherein simultaneously collected data includes data corresponding to a single source location with respect to the image plane.
