The accelerating complexity and variety of medical imaging devices and methods have
outpaced the ability to evaluate and optimize their design and clinical use. This is a …

Medical ultrasound images are reconstructed with simplifying assumptions on wave
propagation, with one of the most prominent assumptions being that the imaging medium is …

Ultrasound localization microscopy (ULM) enables deep tissue microvascular imaging by
localizing and tracking intravenously injected microbubbles circulating in the bloodstream …

Image reconstruction from radio-frequency (RF) data is crucial for ultrafast plane wave
ultrasound (PWUS) imaging. Compared with the traditional delay-and-sum (DAS) method …

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 …

A model and method to accurately estimate the local speed of sound in tissue from pulse-
echo ultrasound data is presented. The model relates the local speeds of sound along a …

Our previous methodology in local sound speed estimation utilized time delays measured by
the cross correlation of delayed full-synthetic aperture channel data to estimate the average …

Acoustic clutter produced by off-axis and multipath scattering is known to cause image
degradation, and in some cases these sources may be the prime determinants of in vivo …

Ultrasound imaging is a widely used diagnostic tool but has limitations in the imaging of
deep lesions or obese patients where the large depth to aperture size ratio (f-number) …

Non‐invasive brain stimulation has the potential to boost neuronal plasticity in the primary
motor cortex (M1), but it remains unclear whether the stimulation of both superficial and …
