A new method for the measurement of ultrasound velocity in long bones is presented. The method can be applied in vitro as well as in vivo. It automatically corrects for the influence of soft tissue, such that the real velocity in bone is obtained. In a series of simulation experiments, hypotheses on the followed wave path were verified. A very good agreement was found between the measurement obtained in the experimental set-up and the values calculated for the hypothesised wave path in the experimental structure. These simulations revealed the feasibility of the technique to determine the velocity in a local site of the structure. Clinical applications of this technique include the monitoring of callus consolidation after fracture and the detection of bone degenerative diseases such as osteoporosis.
提出了一种测量长骨中超声速度的新方法。该方法可用于体外和体内测量。它能自动校正软组织的影响，从而获得骨中的实际速度。在一系列模拟实验中，验证了关于后续波路径的假设。在实验装置中获得的测量结果与实验结构中假设波路径计算的值之间发现了非常好的一致性。这些模拟揭示了该技术在确定结构局部部位速度方面的可行性。该技术的临床应用包括监测骨折后骨痂的愈合以及检测骨质疏松等骨退行性疾病。
