Cone beam computed tomography (CBCT) is widely applied for medical and industrial use recently. But artifacts are always induced due to the misalignments of CBCT components. An improved Feldkamp-Davis-Kress (FDK) algorithm using camera cali...

Image reconstruction from X-ray cone-beam projections collected along a single-circular source trajectory is commonly done using the Feldkamp (FDK) algorithm which performs well only with a small cone-angle. Although this method does not pr...
