Best images obtained by FISTA and OSTR-32. Note that the NFFT-based versions are virtually indistinguishable from the ray-tracing-based ones. The number of iterations and computation time required for obtaining the reconstruction are displayed in the bottom-left and bottom-right corner, respectively, of each image.
