Optimisation of Simultaneous Tl-201/Tc-99m Dual Isotope Reconstruction with Monte-Carlo-Based Scatter Correction

Table 7

Contrast evaluation with the physical phantom. The table shows myocardium versus defect and myocardium versus left ventricle (LV) contrasts for optimised and unoptimised Tl-201/Tc-99m reconstruction and for pure Tl-201 reconstruction. The results were obtained using the Jaszczak phantom with a cardiac insert. Only Tl-201 reconstruction results are shown.
