Abstract
An improved apparatus and method for providing a measurement of the characteristic behavior of an acoustic wave in a bone of a subject. A preferred embodiment has a first assembly containing mounting means for mounting two transducers in spaced relationship with respect to the bone, and a second, hand-holdable assembly containing a display for displaying an output characterizing the behavior of the acoustic wave in the bone. In other embodiments of the invention, an acoustic signal propagated along a path through the bone is processed to determine the proximity of the path to an edge of the bone.
