introduction: the medical applications of ultrasound on human brain are highly limited by the phase and amplitude aberrations induced by the heterogeneities of the skull. however, it has been shown that time reversing coupled with amplitude compensation can overcome these aberrations. in this work, a model for 2d simulation of the time reversal mirror technique is proposed to study the possibil...

This study evaluated the effect of pulsed low-intensity ultrasound on cell proliferation, collagen production and glycosaminoglycan deposition by human dermal fibroblasts encapsulated in alginate. Hoechst 33258 assay for cell number, hydroxyproline assay for collagen content, dimethylmethylene blue assay for glycosaminoglycan content and scanning electron microscopy were performed on the encaps...

Background:Low intensity ultrasound (US) has some well-known bio-effects which are of great importance to be considered.Objectives: We conducted the present study to investigate the effects of low intensity continuous ultrasound on blood cells count in rat.Methods: Rats were anesthetized and blood samples were collected before US exposure. Then, they were exposed to US with nominal intensity of...
