- FIGURE 2.
Transaxial images of striatal phantom with 10:1 striatal-to-background ratio: with no scatter correction (A), with ES scatter correction (B), and with TDCS scatter correction (C). Striatal ROI indicates only pixels in top 2% of striatum and may vary in location for different methods. Background (BKG) ROIs are the same for all methods.
- FIGURE 3.
Relationship between expected and measured striatal-to-background ratios. Each series was fitted with linear regression line. SC = scatter correction.
