Abstract
The present invention discloses a method and a system for supplementing and completing 3D CT data generated from an incomplete scanning path. If a detector is large enough to scan the object, additional data is acquired from adjacent scanning paths and combined directly with the original projection data set in order to form an exact and complete data set called the combined data set. If the object to be scanned is larger than the detector, additional data from adjacent scanning paths is acquired and reconstructed into an approximate image of the adjacent region from which appropriate projection data from the region of interest is calculated to form an exact and complete data set. In either case, a priori information about the object may be used to calculate missing projection information.
