Abstract
An apparatus for performing a measurement that characterizes the behavior of an acoustic wave in a heel bone. The apparatus is an integral unit having a base with a platform coupled to the base at a specified angle with respect to the base for receiving, centering and reproducibly orienting a foot. The apparatus has two transducer arms, each supporting an acoustic transducer in spaced relationship with respect to the foot of the subject and a member for mounting the first and second transducer arms in moveable relationship to the base so as to permit coupled two-dimensional motion of the first and second transducers over regions of the heel. The transducer units have transducer caps and an acoustically absorbing filler medium for emitting an acoustic wave with substantially the character of a point source over an opening angle of at least 30.degree..
