Image Covariance and Lesion Detectability in Direct Fan-Beam X-Ray Computed Tomography

We consider noise in computed tomography images that are reconstructed using the classical direct fan-beam filtered backprojection algorithm, from both full and short-scan data. A new, accurate method for computing image covariance is presented. The utility of the new covariance method is demonstrat...
