Embolus Detection System guided TIA and Stroke management

A new embolus detection system (EDS) is presented, built with the intention to detect ongoing cerebral embolisation in patients at risk of TIA or stroke. It is based on the analysis of the audio-Doppler signal of a transcranial Doppler machine. The algorithm of the EDS estimates the intensity, duration and the zero-crossing dynamics of the audio signal. The EDS has a multi-layer neural network which classifies events into micro-emboli signals (MES) or artefacts. The „decision making“ component of the software has been validated against human experts. Data from patients in the post-operative phase of carotid surg…
