Abstract
We showed in a previous study that the detection of micro-emboli can be markedly improved by taking into account the quasi-cyclostationary properties of the blood Doppler signal. However, in order to detect still smaller events, we propose to combine the use of synchronous detectors and sub-band decomposition. We evaluated and compared the detector´s performance to existing methods by using both numerical modeling of the Doppler signal and ROC curves.
