摘要:

本研究首次观察到在软组织内远程诱发的剪切波。通过经颅磁刺激装置和永磁体的组合进行。建立了基于麦克斯韦方程和纳维尔方程的物理模型。在冷冻凝胶体模和鸡胸肉样品上进行实验。使用超快超声扫描仪,观察到振幅分别为5和0.5微米的剪切波。实验和数值计算结果吻合良好。这项研究构成了一个替代的剪切波弹性成像方法的框架。

英文摘要:

This study presents the first observation of shear wave induced remotely within soft tissues. It was performed through the combination of a transcranial magnetic stimulation device and a permanent magnet. A physical model based on Maxwell and Navier equations was developed. Experiments were performed on a cryogel phantom and a chicken breast sample. Using an ultrafast ultrasound scanner, shear waves of respective amplitude of 5 and 0.5 micrometers were observed. Experimental and numerical results were in good agreement. This study constitutes the framework of an alternative shear wave elastography method.
