A comparison of reflection and transmission ultrasonic techniques for measurement of cancellous bone elasticity
A comparison of reflection and transmission ultrasonic techniques for measurement of cancellous bone elasticity
- Journal of Biomechanics, 27(9), p.1195-1199, 1994 .
A reflection ultrasonic technique, which offers several advantages over transmission ultrasonic techniques, has been described for elastic property measurement of bone. Ultrasonic velocities from specimens of cancellous bone were compared using a reflection ultrasound technique and the more traditional transmission ultrasonic technique. The two techniques were found to yield velocities which were reasonably well correlated (r2 = 0.74). However, a statistical difference was found between the line of identity and the regression between transmission and reflection velocities (due to an offset in the intercept). In spite of differences in intercept between velocities measured by the two techniques, significant correlation was found between the two methods, suggesting that the reflection technique can measure wave velocities meaningful to bone elasticity.
