- W4235424817 abstract "This study was carried out to reconstruct quantitative images in simultaneous /sup 123/I//sup 99m/Tc SPECT. In the /sup 123/I//sup 99m/Tc SPECT study the image reconstructed with the counts of primary photons emitted from the radionuclide with low photopeak energy (/sup 99m/Tc) is distorted by Compton scattered photons originating in the radionuclide with high photopeak energy (/sup 123/I). To correct the scattered photons included in the low energy photopeak window in the simultaneous data acquisition, we proposed a method with a neural network at the 1999 IEE Medical Imaging Conference. In this paper we investigated the performance of our method with Monte Carlo simulations and phantom experiments with a brain phantom and a myocardial phantom. The results showed that our method could separate /sup 99m/Tc and /sup 123/I with an error of about 4% The results promised to enable us to make clinical trials with dual radionuclides." @default.
