*'''Bone Surface (BS)''':   A measure of the bone surface area.  Measured using the Marching Cubes method to triangulate (TRI) the surface.  Output units are mm2.  

*'''Structure Model Index (SMI)''':  An estimation of the plate-rod characteristic of the bone structure.  SMI is calculated from the curvature of a triangulated surface (TRI) of the structure from the equation:  SMI=6{[BV(dBS/dr)]/BS2].  For an ideal plate structure SMI=0 and for an ideal rod structure SMI=3.  This is a dimensionless (non-metric) parameter.
