A new method, based on the microdefocusing method for transcutaneously measuring velocity of leaky surface skimming compressional waves (LSSCWs), propagating on the surface of bone, is proposed. The method uses an ultrasonic measuring system that is applicable to measuring in vivo using ultrasound of 1 MHz. Velocity of the LSSCW propagating on the surface of a Bakelite sample was accurately determined in a preliminary experiment, and the principle underlying the method was confirmed.
