ABSTRACT:
An apparatus and methods determine externally in a vertebrate subject the porosity and non-connectivity of a bone. A preferred embodiment has an acoustic transceiver with a pair of acoustic transducers disposed in a specified spatial relationship with one another, such that an acoustic signal is transmitted from one to another via the bone. The transmission path through the bone corresponding to the acoustic signal analyzed by the system may be varied, with values derived from measures of acoustic transmission through differing locations in the bone stored in different locations of a memory. A location processor is provided for selecting a target location based at least in part on the values stored in the memory for defining a region of interest with respect to which a measure of bone porosity is determined.
