Abstract

To accurately simulate the down-scatter of Tc-99m photons in the Gd-153 transmission window and in the Tl-201 photopeak projection, the effect of partial energy deposition in the crystal, of collimator scatter and of lead x-rays were included within an accelerated Monte Carlo (MC) framework. It was shown that for accurate modeling of down-scatter, all these effects are important. In particular, a significant increase in accuracy of simulated projections was accomplished when these effects were included.
