The source and density maps were created from BAM. The source map involved both background and striatal regions. The ratio of the striatal to background region accumulation was set to rates of 8:1, 6:1, and 4:1. The density map consisted of two parts only—bone and non-bone—and each density was 1.22 g/cm3 and 1.04 g/cm3, respectively.
