calculated bone section morphological measurement bone section structure model index 2017-01-19T17:30:31Z A quantitative measure of bone microarchitecture calculated by means of three-dimensional image analysis and based on the volume ratio of plate-shaped trabeculae to rod-shaped ones. For bones which contain both structures the value is expected to be between 0 (all parallel plates) and 3 (all cylindrical rods) although a value of 4 is possible (denoting spherical trabeculae). Also, where the fraction of mineralized tissue in a bone section is extremely high or low, values outside this 0-4 range are possible.
