Spatial variation in vBMDtrab measurement for phantoms scanned in water with the 200 mg HA/cm3 correction. Percent error is plotted against percent of full diameter included in the analyzed region of interest (ROI). Measured vBMDtrab is highest at the periphery of the insert, decreasing towards the center of the cross-section. Results are shown for shell thicknesses of 1.0 mm (tibia) and 0.5 mm (radius) and for all insert densities (60 mg HA/cm3 through 360 mg HA/cm3). Results for all shell thicknesses follow the same trends (data not shown).
