Abstract

Abstract: For the safe and simple screening of equine leg bones, we applied an ultrasonic axial transmission (AT) technique to an equine bone sample with a weak bucked shin. Both experimental and simulation studies have been conducted. To simulate by the finite-difference time-domain method, a digital model of the equine leg bone was fabricated. The experimental and simulation results showed a similar tendency. The obtained apparent wave velocities in the axial direction were almost constant in the healthy part but strongly fluctuated in the bucked shin part because of the small surface irregularities. The standard deviation values of the wave velocities in the bucked shin parts were large. These results indicate that a weak bucked shin in the equine leg bone may be screened clinically by a simple evaluation of velocity fluctuation using the AT technique.
