图2 脑组织MRE成像的主要流程.剪切波激励包括波动信号的发生、放大与通过驱动器向脑组织中的传递；剪切波记录包括采用MRE扫描序列对磁共振成像系统操作记录波动位移；图像后处理部分包括图像的重建与基于波动影像的生物力学参量反演计算

Fig. 2 Procedures of brain MRE. The wave actuation includes generating, amplifying, and transmitting shear waves to brain. The recording of waves include using MRE sequence implemented in the MR scanner for displacement encoding. The image processing steps include image reconstruction and inversion of biomechanical properties
