Background:
Ultrasound elastography, specifically shear wave elastography (SWE), is essential for non-invasive assessment of tissue stiffness, an important biomarker for diagnosing and monitoring diseases such as liver fibrosis, cancer, and ocular conditions. While conventional two-dimensional SWE provides valuable clinical insights, accurately characterizing...
