Three novel methods are used to reconstruct a simulated image from a set of incomplete data spanning a 160 degrees angular range. These methods are the squashing affine transformation of J.A. Reeds and L.A. Shepp (1987), the circular interpolation method derived from the theory of J.J. Clark, M.R. Plamer, and P.D. Lawrence (1985), and the geometry-free reconstruction using the theory of convex projections. These methods are briefly explained, and their reconstructions are compared for the case of limited angular views.
