During the past decade, ultrasound has expanded medical imaging well beyond the
“traditional” radiology setting: a combination of portability, low cost, and ease of use makes …

Conventional ultrasound images are formed by delay-and-sum beamforming of the
backscattered echoes received by individual elements of the transducer aperture. Although …

Minimally invasive surgeries often require complicated maneuvers and delicate hand–eye
coordination and ideally would incorporate “x-ray vision” to see beyond tool tips and …

Blind source separation (BSS) refers to a number of signal processing techniques that
decompose a signal into several “source” signals. In recent years, BSS is increasingly …

Hepatic steatosis is a common condition, the prevalence of which is increasing along with
non-alcoholic fatty liver disease (NAFLD). Currently, the most accurate noninvasive imaging …

A general filtering method, called the singular value filter (SVF), is presented as a framework
for principal component analysis (PCA) based filter design in medical ultrasound imaging …

In intraoperative settings, the presence of acoustic clutter and reflection artifacts from
metallic surgical tools often reduces the effectiveness of ultrasound imaging and …

We demonstrate a novel imaging technique, named short-lag spatial coherence (SLSC)
imaging, which uses short distance (or lag) values of the coherence function of …

Ultrasound super-resolution techniques use the response of microbubble (MB) contrast
agents to visualize the microvasculature. Techniques that localize isolated bubble signals …

Short-lag spatial coherence (SLSC) imaging is a novel beamforming technique that reduces
acoustic clutter in ultrasound images. A clinical study was conducted to investigate clutter …
