Development of a cone angle weighted three-dimensional image reconstruction algorithm to reduce cone-beam artefacts

Image reconstruction from cone-beam projections collected along a single circular source trajectory is commonly done using the Feldkamp algorithm, which performs well only with a small cone angle. In this report, we propose an algorithm to reduce cone-beam artefacts by increasing the cone angle by s...
