Description
The aim of this study in to measure the distributions of multiple isotopes in small animal SPECT study. In multi-isotope SPECT system, images reconstructed with the counts of primary photons emitted from a low energy photopeak radionuclide is distorted by Compton scattered photons originating in a high energy photopeak radionuclide.. In this paper, applied an artificial neural network method to quantitatively measure the distribution of activities in the simultaneous data acquisition with a multiple isotope SPECT study and the accuracy of our proposed method was evaluated.
