Abstract
Three-dimensional, conebeam image reconstruction from planar, transmitted x-ray projections is the most dose-efficient method for computed tomography. A number of factors, including the number of projections acquired, the cone angle subtended by the detector, the detector bit- depth, and the amount of noise in the projections, influence the quality of the reconstruction. Using simulations, we investigate the effects of these parameters on the signal-to-noise level attainable using the Feldkamp algorithm for conebeam reconstruction.
