Randomized Multiresolution Scanning in Focal and Fast E/MEG Sensing of Brain Activity with a Variable Depth
Atena Rezaei, Alexandra Koulouri, Sampsa Pursiainen
We focus on electromagnetoencephalography imaging of the neural activity and, in particular, finding a robust estimate for the primary current distribution via the hierarchical Bay…
Simultaneous Skull Conductivity and Focal Source Imaging from EEG Recordings with the help of Bayesian Uncertainty Modelling
Alexandra Koulouri, Ville Rimpilainen
The electroencephalography (EEG) source imaging problem is very sensitive to the electrical modelling of the skull of the patient under examination. Unfortunately, the currently av…
Electrical Impedance Tomography with Box Constraint for Skull Conductivity Estimation
Ville Rimpilainen, Theodoros Samaras, Alexandra Koulouri
Unknown electric conductivities of human tissues is a common issue in medical engineering. Electrical impedance tomography (EIT) is an imaging modality that can be used to determin…
Position Dilution of Precision: a Bayesian point of view
Alexandra Koulouri, Ville Rimpiläinen, Nathan D. Smith
The expected position error in many cases is far from feasible to be estimated experimentally using real satellite measurements which makes the model-based position dilution of pre…
Methodology to estimate ionospheric scintillation risk maps and their contribution to position dilution of precision on the ground
Alexandra Koulouri, Nathan D. Smith, Bruno C. Vani +3
Satellite-based communications, navigation systems and many scientific instruments rely on observations of trans-ionospheric signals. The quality of these signals can be deteriorat…
