In this paper we address the problem of interpreting ultrasound images obtained from doppler devices in order to classify, and hence to distinguish, the dangerous cerebral microemboli from the innocuous ones. In order to obtain an automatic categorisation of the cerebral high intensity transient signal, a multilevel neural network based on a hierarchical architecture has been implemented for image processing and classification. The images, obtained by measuring the blood flow velocities in brain arteries and veins,have been acquired using the 'Multi Dop X4' ultrasound device by DWL. The approach proposed, applied to real clinical cases selected by expert neurologists for their peculiar characteristics, has shown to be a valid real-time support for the diagnosis of cerebral vascular diseases
