FIGURE 7. Comparison of electron absorbed fraction data, (TAMTAM), for self-irradiation of TAM within femoral head of 51-y-old man (A) and that of 82-y-old woman (B). At each value of marrow cellularity, simulation results are shown for all 3 methods of adipocyte introduction within marrow cavities of 3D NMR image: DEFINED method (dashed curves), RANDOM method (solid curves), and 3-Voxel method used previously by Bolch et al. (9) (data symbols).
