Table 1.
The activity configuration of the NCAT phantoms. The table shows the relative activity concentrations per pixel and the defect parameters for the NCAT phantoms. The same parameters were used for both the female and male phantoms
| Phantom | Isotope | Myocardium activity | Ventricle activity | Lung activity | Liver activity | Back-ground tissue activity | Defect position | Activity in defect versus myocardium (%) |
