Mapping Heterogeneous Elastic Property Distribution of Soft Tissues Using Harmonic Motion Data: A Theoretical Study

Figure 7

(a) The target shear modulus distribution; ((b)–(d)) the reconstructed shear modulus distributions when the driving frequency increases by 3%, 5%, and 10% in the inverse problem, respectively. In this case, the exact driving frequency is 20Hz and noise level is 3%.
