Magnetic resonance elastography (MRE) is a new solution to detect and visualize the biomechanical properties of soft tissues. Brain lesions often lead to the changes of biomechanical properties. Therefore, the study of brain soft tissues by using MRE has great significance. However, the study confronts of the complicated brain structure, as well as the costs of MRE scanning. It is thus attractive to develop an effective numerical MRE platform which can depict the propagation of various elastic wave probes through brain tissues. On one hand, the results lead to the quantitative evaluation of the efficiency of various elastic wave probes. On the other hand, they can support the study of new MRE algorithms for elasticity reconstruction. A series of quantitative experiments have been carried out, and the results validate the effectiveness of this numerical MRE platform.
