Optimized analytic reconstruction for SPECT

  • Jean-Pol Guillement EMAIL logo and Roman G. Novikov


We develop optimized analytic reconstruction for the single-photon emission computed tomography (SPECT). This reconstruction is based on (1) Novikov's exact and Chang's approximate inversion formulas for the attenuated ray transform, (2) filtering techniques, and (3) Morozov type discrepancy principle. Our numerical examples include comparisons with the standard least square and expectation maximization iterative SPECT reconstructions.
