Gaseous and solid emboli differentiation using radiation force
Abstract : Cerebral embolisms represent a major part of all ischemic strokes in western countries. It has been found that a good knowledge of emboli (detection, differentiation and sizing), which are foreign particles to blood normal cerebral circulation, remains a promising challenge. Their characterization can be used, in fact, as a diagnostic or therapeutic tool. The most commonly used tool to detect emboli is a transcranial Doppler system. Clinical studies have shown that in the embolic Doppler signature of patient having a prosthetic heart valve present a high frequency modulation index while for patient having atherosclerotic plaque the frequency modulation index is low. We hypothesis that this high level modulation index is probably induced by the radiation force effect (trajectory modification). We will show in this study that it is possible, by using the radiation force, to discriminate gaseous to particulate emboli.
