摘要: A reflection ultrasonic technique, which offers several advantages over transmission techniques, has been described for elastic property measurement of bone. Ultrasonic velocities from specimens cancellous bone were compared using a ultrasound technique and the more traditional technique. The two techniques found to yield reasonably well correlated (r2 = 0.74). However, statistical difference was between line identity regression (due an offset in intercept). In spite differences intercept measured by significant correlation methods, suggesting that can measure wave meaningful elasticity.
