Abstract

Ultrasonic wave propagation in human cancellous bone is considered using Biot's theory modified by the Johnson-Koplik-Dashen model for viscous exchange between fluid and structure. The transmission coefficient is derived for a slab of porous material. Experimental results for fast and slow waves transmitted through human cancellous bone samples are given and compared with theoretical predictions.

摘要

利用由约翰逊 - 科普利克 - 达申模型修正的比奥理论来考虑超声波在人体松质骨中的传播，该模型用于描述流体与结构之间的粘性交换。推导了多孔材料平板的传输系数。给出了通过人体松质骨样本传输的快波和慢波的实验结果，并与理论预测进行了比较。
