For more than two decades, the Ultrasonic Acoustics Laboratory (LAU-FCIEN-Uruguay), the Langevin Institute (CNRS/ ESPCI PSL Paris France) and the Institute of Physics for Medicine (Inserm/CNRS/ESPCI PSL Paris France) have been collaborating on multiple research projects in biomedical ultrasound ranging from shear wave elastography to ultrafast imaging and neuroscience. In this talk, a brief summary is given of the LAU’s scientific activities. One of the most recent topics of collaboration between Physics for Medicine and the LAU is also described, namely the study of vascular dynamics in mouse brains in order to analyze neurodegenerative diseases. Finally, recent developments of Physics for Medicine team in Ultrafast Ultrasound, neurofunctional Ultrasound and Ultrasound Localization Microscopy imaging methods will also be described.
