Independent component analysis: fetal signal reconstruction from magnetocardiographic recordings
Independent component analysis (ICA) was used for the processing of cardiological signals obtained by means of fetal magnetocardiography (fMCG), a technique allowing the non-invasive recording of the weak magnetic field variations associated to the electrical activity of the fetal heart. Purpose of the present work was to verify whether a computational-light ICA algorithm (FastICA), tailored to...
متن کاملEvaluating dipolar source localization feasibility from intracerebral SEEG recordings
Stereo-electroencephalography (SEEG) is considered as the golden standard for exploring targeted structures during pre-surgical evaluation in drug-resistant partial epilepsy. The depth electrodes, inserted in the brain, consist of several collinear measuring contacts (sensors). Clinical routine analysis of SEEG signals is performed on bipolar montage, providing a focal view of the explored stru...
متن کاملDecentralized Source Localization and Tracking
This paper describes a new approach to the source localization and tracking problem in wireless sensor networks. A fast, easy-toimplement algorithm for localizing a source using received signal strength measurements is presented. The algorithm is based on incremental subgradient optimization methods. Using theory on the convergence rates of these methods we characterize the amount of in-network...
متن کاملBeat-to-beat analysis method for magnetocardiographic recordings during interventions.
Multichannel magnetocardiography (MCG) during exercise testing has been shown to detect myocardial ischaemia in patients with coronary artery disease. Previous studies on exercise MCG have focused on one or few time intervals during the recovery period and only a fragment of the data available has been utilized. We present a method for beat-to-beat analysis and parametrization of the MCG signal...
متن کاملFetal Magnetocardiographic Source Separation Using the Poles of the Autocorrelation Function
Fetal magnetocardiography (FMCG) have been extensively reported in the literature as a non-invasive, prenatal technique, in which magnetic fields are used to monitor the function of the fetal heart rate. On the other hand, FMCG may be highly noisy, due to the fetal heart dimensions when compared, for example, to the mother’s. In the field of source separation, many works have shown its efficien...
