Towards Transcranial 3D Ultrasound Localization Microscopy of the Nonhuman Primate Brain

Paul Xing, Vincent Perrot, Adan Ulises Dominguez-Vargas +3

Hemodynamic changes occur in stroke and neurodegenerative diseases. Developing imaging techniques allowing the in vivo visualization and quantification of cerebral blood flow would…

Equivalent Time Active Cavitation Imaging

Simon Blais, Jonathan Poree, Gerardo Ramos-Palacios +4

The development of neurologically active drugs faces a challenge in treating brain diseases due to the blood-brain barrier's impermeability. High-intensity focused ultrasound can o…

Ergodic encoding for single-element ultrasound imaging in vivo

Olivier Caron-Grenier, Jonathan Poree, Vincent Perrot +3

Conventional ultrasound imaging relies on the computation of geometric time delay from multiple sensors to detect the position of a scatterer. In this paper, we present Ergodic Rel…

Quantitative pulsatility measurements using 3D Dynamic Ultrasound Localization Microscopy

Chloé Bourquin, Jonathan Porée, Brice Rauby +11

A rise in blood flow velocity variations (i.e., pulsatility) in the brain, caused by the stiffening of upstream arteries, is associated with cognitive impairment and neurodegenerat…

So you think you can DAS? A viewpoint on delay-and-sum beamforming

Vincent Perrot, Maxime Polichetti, François Varray +1

Delay-and-sum (DAS) is the most widespread digital beamformer in high-frame-rate ultrasound imaging. Its implementation is simple and compatible with real-time applications. In thi…
