Medical ultrasound images are reconstructed with simplifying assumptions on wave propagation, with one of the most prominent assumptions being that the imaging medium is composed of a constant sound speed. When the assumption of a constant sound spee

Abstract 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) reduces image quality. Reducing the f-number can improve image q

Volumetric ultrasound imaging has the potential for operator-independent acquisition and enhanced field of view. Panoramic acquisition has many applications across ultrasound; spanning musculoskeletal, liver, breast, and pediatric imaging; and image-

The rise of ultrafast ultrasound imaging—with plane or diverging waves - paved the way to new applications of ultrasound in biomedical applications. However, propagation through complex layers (typically fat, muscle, and bone) hinder considerably t

We propose here a real time approach for aberration correction and Speed Of Sound quantification in the context of ultrafast ultrasound imaging. Theoretical works demonstrate the physical meaning of Singular Value Decomposition of the Ultrafast Compo

The rise of plane or diverging ultrasound waves allowed to perform high quality imaging at much faster frame rates. Though, propagation through complex layers induces phase and amplitude aberrations that remain partially unresolved. In ultrafast ultr

A shift of paradigm is currently underway in biomedical ultrasound thanks to plane or diverging waves coherent compounding for faster imaging. One remaining challenge consists in handling phase and amplitude aberrations induced during the ultrasonic

The non-invasive quantification of human tissue fat fraction using easily scalable and accessible imaging technologies is crucial for the diagnosis of many diseases including liver steatosis. Here, we propose a non-invasive quantification of fat cont
