本文研究了超声在松质牛股骨内衰减和速度的测量。测量了0.2 ~ 0.8 MHz之间的衰减和速度与骨密度的关系。结果表明，衰减和密度的相关系数约为0.5，速度和密度的相关系数约为0.85。本文讨论了使用低频超声作为骨病诊断工具的临床后果。
The measurements of attenuation and velocity of ultrasound in cancellous bovine femora has been studied. The dependence of both attentuation between 0.2 and 0.8 MHz and velocity on the bone density has been measured. The results show a correlation coefficient of around 0.5 for attenuation and density, and a value of roughly 0.85 for velocity and density. The clinical consequences for the use of low frequency ultrasound as a diagnostic tool in bone disease are discussed.
