Conventional delay-and-sum (DAS) beamforming is highly efficient but also suffers from various sources of image degradation. Several adaptive beamformers have been proposed to address this problem, including more recently proposed deep learning metho

We perform finite element modeling of pulse-echo ultrasound of a hard inclusion in a soft tissue to gain a better understanding of B-mode image brightness characteristics. We simulate a pressure wave emitted by an ultrasound transducer through the in

Acoustic clutter is a primary source of image degradation in ultrasound imaging. In the context of flow imaging, tissue and acoustic clutter signals are often much larger in magnitude than the blood signal, which limits the sensitivity of conventiona

Trans-arterial chemoembolization (TACE) is an important yet variably effective treatment for management of hepatic malignancies. Lack of response can be in part due to inability to assess treatment adequacy in real-time. Gold-standard contrast enhanc

Improving ultrasound B-mode image quality remains an important area of research. Recently, there has been increased interest in using deep neural networks (DNNs) to perform beamforming to improve image quality more efficiently. Several approaches hav

Non-contrast ultrasound blood flow imaging is difficult at slow blood flow rates. Singular value decomposition (SVD) and independent component analysis (ICA) are useful for separating tissue, blood, and noise sources for Doppler filtering. In additio

Immediate postoperative assessment of trans-arterial chemoembolization (TACE) using gold standard modalities, MRI and CT, is unreliable due to confounding interactions with lipiodol and post-embolization inflammatory changes. We previously demonstrat

Deep neural networks (DNNs) have previously been used to perform adaptive beamforming and improve image quality compared to conventional delay-and-sum (DAS). Although effective, low training validation loss is often not correlated to improved image q
