Emil Y. Sidky, Rick Chartrand and Xiaochuan Pan, "Image reconstruction from few views by non-convex optimization", in IEEE Nuclear Science Symposium Conference Record, 2007


Image reconstruction for fan-beam computed tomography (CT) from projection data containing a small number of views is investigated. An iterative algorithm is developed that seeks to minimize the total p-variation of the reconstructed image subject to the constraint that the estimated projection data agree with the available data to within a specified data tolerance ε. A preliminary investigation of the dependence of image quality as a function of p and ε is performed.
