Figure 10
Images representing (a) linear attenuation and (c) mass energy absorption coefficients at 35 keV. Graphs compare model predictions (points) for regions of rodent (A) adipose, (M) muscle and (S) spine, against (lines) calculations using the mixture rule and tabulations (Cullen et al., 1989; Hubbell & Seltzer, 1995; Boone & Chavez, 1996) for cortical bone (1 year-old child), soft tissue (ICRU 44 formulation), water and adipose (adult). |
