New ultrasound methods that can be used to quantitatively assess liver fat content have
recently been developed. These quantitative ultrasound (QUS) methods are based on the …

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

Photoacoustic imaging (PAI) has attracted great attention as a medical imaging method.
Typically, photoacoustic (PA) images are reconstructed via beamforming, but many factors …

Matrix imaging paves the way towards a next revolution in wave physics. Based on the
response matrix recorded between a set of sensors, it enables an optimized compensation …

Non-alcoholic fatty liver disease is a condition that is characterized by the presence of> 5%
fat in the liver and affects more than one billion people worldwide. If adequate and early …

Computed ultrasound tomography in echo mode (CUTE) allows determining the spatial
distribution of speed-of-sound (SoS) inside tissue using handheld pulse-echo ultrasound …

Imaging has become an essential tool in modern radiotherapy (RT), being used to plan dose
delivery prior to treatment and verify target position before and during treatment. Ultrasound …

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 …

Focusing waves inside inhomogeneous media is a fundamental problem for imaging.
Spatial variations of wave velocity can strongly distort propagating wave fronts and degrade …

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 …
