background: initial studies have shown that low-energy ultrasound stimulates living tissue cells to reduce regeneration or speed up their recovery. the purpose of this study was to examine the effects of various ultrasound parameters on the speed of recovery in injured sciatic nerves. methods: nmri mice (n = 200) with injured left paw, caused by crushing their sciatic nerves, were randomly sele...

High-intensity focused ultrasound therapy is a novel, emerging, therapeutic modality that uses ultrasound waves, propagated through tissue media, as carriers of energy. This completely non-invasive technology has great potential for tumor ablation as well as hemostasis, thrombolysis and targeted drug/gene delivery. However, the application of this technology still has many drawbacks. It is expe...

ally small, between 0% and 6%, for most dichotomous outcomes. Conclusion. The evidence from the five small placebocontrolled trials included in this review does not support the use of ultrasound in the treatment of acute ankle sprains. The potential treatment effects of ultrasound appear to be generally small and probably of limited clinical importance, especially in the context of the short-te...

It is shown that a simple metal plate serving as a mirror decisively improves ultrasound mammography. A suitable reconstruction algorithm is described. A numerical example based on computer simulations is given.
