Evaluating the Improvement in Shear Wave Speed Estimation Affected by Reflections in Tissue

Elastography has emerged as a promising technique for non-invasive clinical diagnosis in recent years. This method estimates tissue elasticity by analyzing the speed of shear waves captured by an ultrasonic Doppler transducer, and offers several advantages such as high reliability, low cost, and non-invasiveness. However, the propagation of sliding waves in diseased tissue generates reflected waves that can affect the accuracy of the results. To overcome this limitation, this study introduces a novel technique that employs a directional filter to eliminate reflected waves and increase the reliability of the elastography results. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
