抜粋

A recently proposed system for diagnosing osteoporosis by measuring the acoustic impedance of bone fails to provide the necessary step of taking reflection loss at the interface between the bone and the soft tissue as well as propagation loss in the soft tissue into account. Here we propose an ultrasonic reflection method that compensates for these losses. Preliminary experiments using PMMA/Bakelite and rubber/Bakelite composite models indicate the validity of this method. Values obtained in vivo with and without compensation differed significantly.
