Background
Functional ultrasound imaging is a promising neuroimaging technology with potential to unlock next-generation brain-computer interfaces (BCI). However, ultrasound imaging through the skull is limited by the impedance mismatch between bone and brain tissue, causing reflection, scattering, and signal loss, resulting in poor transmission and...

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...
