摘要：Tissue compression simulation model is important to design and evaluate strain estimating and imaging algorithm in ultrasonic elastography. A new tissue compression simulation model was present based on the separate scattering model of biological tissues. By changing amplitude and phase of the simulated signal, controllable decorrelation between the pre-and post-compression signals can be practiced. Moreover, the controllable decorrelation can change with the examined tissue depth when compared to the other simulation models in elastography. The validity of the model was examined by tissue compression experiments in-vitro.
