Monte Carlo (MC) simulation has become an important tool for characterizing and evaluating imaging systems and reconstruction algorithms. In this work, we combined two MC codes-Monte Carlo N-particle transport code system (MCNP) and simulation system

In simultaneous Tl-201 and Tc-99m dual isotope imaging, Pb X-rays are a significant source of contamination in the Tl image. In order to characterize this contamination, we simulated images of line sources in the Tc and Tl photopeak windows using an

Several studies have differentiated Alzheimer's disease (AD) using cerebral image features derived from MR brain images. In this study, we were interested in combining hippocampus and amygdala volumes and entorhinal cortex thickness to improve the pe

Currently, many software packages for the internal radiation dosimetry have been developed. Many of them do not provide sufficient tools to perform all of the necessary steps from nuclear medicine image analysis for dose calculation. For this reason,

This preliminary study is to improve /sup 67/Ga planar and SPECT images by compensating for the response function of a medium energy (ME) collimator. The point response functions (PRFs) of a GE ME collimator for the 93, 185 and 300 keV photons of /su

Clinical use of Tl-201 and Tc-99m dual isotope myocardial SPECT requires compensation for crosstalk contamination of the Tl-210 data. The most significant sources of the crosstalk are Tc-99m downscatter and Pb X-rays generated by the interaction of T
