Abstract

A method and system to perform region-of-interest (ROI) reconstruction is provided, even if the original projection data are truncated. The reconstruction is performed on a superset of the ROI, including the ROI as well as other areas which are outside the scan field-of-view of the imaging system but still within the imaging bore.
