Embolic Doppler ultrasound signal detection using continuous wavelet transform to detect multiple vascular emboli.

Abstract

BACKGROUND Ischemic stroke is mainly caused by embolism. Vascular emboli can be solid or gaseous and can be non-invasively registered by transcranial Doppler ultrasound as microembolic signals (MESs). The existing methods are limited as they do not distinguish between cases in which a single embolus is present and those in which multiple emboli -- perhaps a… (More)
