Abstract
A knowledge of the distribution of the attenuation coefficient is generally required for a successful correction of attenuation in nonhomogeneous regions. This can be accomplished by performing transmission measurement with either parallel or fan-bean collimation. The Monte Carlo method makes it possible to fully evaluate the results of such a correction. This study shows results from such simulations for both parallel and fan-beam transmission imaging. Also, examples of the effect of down-scatter from an emission 99mTc radionuclide into the energy window for a transmission 153Gd radionuclide are shown.
