Resum
I is a commonly used radioisotope employed in neurotransmitter SPECT studies. In addition to an intense line at 159 keV, the decay scheme of this radioisotope includes a low yield ( 3%) of higher energy photons which make a non-negligible contribution to the final image when low-energy high-resolution (LEHR) collimators are used. This contribution of high-energy photons may reach 28% of the total counts in the projections. The aim of this work is to model each energy component of the high-energy...
