An Efficient Estimation Method for Reducing the Axial Intensity Drop in Circular Cone-Beam CT
Reconstruction algorithms for circular cone-beam (CB) scans have been extensively studied in the literature. Since insufficient data are measured, an exact reconstruction is impossible for such a geometry. If the reconstruction algorithm assumes zeros for the missing data, such as the standard FDK a...
