calculated bone section morphological measurement bone section connectivity density 2017-01-19T17:32:39Z A measure of the degree of connectivity of trabeculae divided by the total volume of the bone sample. The degree of connectivity is an index calculated from the Euler number, a fundamental topologic measure counting the number of objects, the number of marrow cavities fully surrounded by bone, and the number of connections that must be broken to split the structure in two parts.
