Derivation of elastic stiffness from site-matched mineral density and acoustic impedance maps.

Journal article

200 MHz acoustic impedance maps and site-matched synchrotron radiation micro computed tomography (SR-muCT) maps of tissue degree of mineralization of bone (DMB) were used to derive the elastic coefficient c(33) in cross sections of human cortical bone. To accomplish this goal, a model was developed to relate the DMB accessible with SR-muCT to mass density. The formulation incorporates the volume fractions and densities of the major bone tissue components (collagen, mineral and water), and acc...
