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

Traditional pulse-echo ultrasound imaging heavily relies on the discernment of signals
based on their relative magnitudes but is limited in its ability to mitigate sources of image …

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 …

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

This is the second article in a series of two which report on a matrix approach for ultrasound
imaging in heterogeneous media. This article describes the quantification and correction of …

Ultrasound Localization Microscopy (ULM) can map microvessels at a resolution of a few
micrometers (). Transcranial ULM remains challenging in presence of aberrations caused by …

The FDORT method (French acronym for decomposition of the time reversal operator using
focused beams) is a time reversal based method that can detect point scatterers in a …

Background An aberration correction algorithm has been implemented and demonstrated in
an echocardiographic clinical trial using two-dimensional (2D) imaging. The method …

While medical ultrasound imaging has become one of the most widely used imaging
modalities in clinics, it often suffers from suboptimal image quality, especially in technically …

The possibility to apply ultrasonic waves, ie, high-frequency acoustic waves, for therapeutic
purposes was recognized over 60 years ago. Chapter 1 of this dissertation establishes the …
