Abstract :
A number of different techniques for reconstructing objects from their projections have evolved in the past two decades. The authors attempt to make a quantitative comparison of some of these techniques for reconstruction of two-dimensional objects from one-dimensional projections. The algorithms under test are: algebraic reconstruction technique, probabilistic method, convolution, and Fourier space algorithms. Error measures are computed for various sets of projections.<>
