It is a non-invasive, cost-effective and highly reliable method. This approach estimates the elasticity and viscosity of diseased tissue by utilizing an ultrasonic Doppler probe to measure the velocity of shear waves. However, this technique faces challenges due to the presence of noise caused by reflected waves and random noise, which can impact the accuracy of the results. To address this issue. we employ a directional filter to eliminate reflection noise before using a Kalman filter to estimate elasticity and viscosity.
