Enhancing Shear Wave Estimation Through Directional and Kalman Filters for Noise Reduction

EasyChair Preprint 10619, version 1

Abstract

The tissue elastography ultrasound technique has witnessed significant advancements in recent years. 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.
