Figure 7.
Results for when the tumor location (as displayed in figure 2b) is known but the size of the tumor model employed in SLE and ROI estimation is inaccurate (errors in volumes: ±%50). Average SLE and ROI estimated activities plotted relative to the true activities for the uniform background. Plots in the middle row are for the ideal cases (figure 4, 1st row), where the correct tumor model (both size and location) is used.
