Noninvasive method for measuring velocity of leaky surface skimming compressional wave propagating on bone surface

The authors propose a new method, based on the microdefocusing method, for trancutaneously measuring the velocity of leaky surface skimming compressional waves (LSSCWs) propagating on the surface of bone. The method is realised by an ultrasonic measurement system which is applicable to in vivo measurement using ultrasound of 1 MHz. The velocity of the LSSCW propagating on the surface of a Bakelite sample is successfully determined in a preliminary experiment, and the principle of the proposed method is confirmed
