    • Two-dimensional viscoelastic imaging using an enhanced FDTD-AHI approach
    Authors: Tran, Quang-Huy;  Advisor: Nguyen, Thi Hoang Yen; Le, Truong Giang; Tran, Duc-Tan T;  Co-Author: - (2021)

    Ultrasound viscoelastography is a quantitative and convenient imaging model that images soft tissues based on shear waves’ propagation. Thanks to the interaction between ultrasonic waves and shear waves, the physical features of soft tissues (elasticity, viscosity) are expressed by complex shear modulus (CSM) parameters, useful information for diagnosing tissue medical states. Therefore, this paper presented a new efficient approach to estimate CSM and reconstruct the viscoelastic images.
