In vivo acoustic and photoacoustic focusing of circulating cells [PDF]
Scientific Reports, 2016 AbstractIn vivo flow cytometry using vessels as natural tubes with native cell flows has revolutionized the study of rare circulating tumor cells in a complex blood background. However, the presence of many blood cells in the detection volume makes it difficult to count each cell in this volume. We introduce method for manipulation of circulating cells

Characterization of focused-ultrasound-induced acoustic streaming [PDF]
Experimental Thermal and Fluid Science, 2019 This study is interested in one of the hydrodynamic mechanisms induced by High Intensity Focused Ultrasound (HIFU) propagation in a liquid medium, the acoustic streaming phenomenon. The latter is a flow generation caused by acoustic energy viscous dissipation during acoustic wave propagation in a fluid medium. Particle Image Velocimetry (PIV) technique
