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

Table 3

The contrast values for the Tc-99m optimization. In this table myocardium versus defect and myocardium versus left ventricle (LV) contrasts are presented for the Tc-99m optimisation. The contrast values were calculated for Phantom 3 that had an anterior defect.
