Magnetocardiography Signal Reconstruction With Reduced Source Space Based on Current Source Variance

Sparse current source reconstruction in MCG

“…One significant approach is to noninvasively image distributed current sources in the 3D volume by seeking related inverse solutions. Efforts to implement this have been performed in fields of electroencephalography (EEG) [1][2][3], magnetoencephalography (MEG) [4] and magnetocardiography (MCG) [5][6][7][8]. Although the various investigations are based on different measurement data, the mathematical models used and methodologies applied are much the same.…”

Cardiac electrical activity imaging of patients with CRBBB or CLBBB in magnetocardiography

“…[4][5][6][7][8] Thenceforth, equivalent dipole solutions were investigated with the aim of functional source localization in electrocardiograms or magnetocardiograms. [9][10][11] In recent decades, the reconstruction of the current dipole of the cardiac magnetic field has been studied using the distributed source model [12][13][14][15] or the current multipole model, [16,17] whereby the intracellular current is approximated as a set of equivalent dipoles with fixed positions in the heart. The use of distributed source solutions not only overcomes the ill-posed problem in source parameter calculations, but also has the ability to extract local information about cardiac electrical activity on the surface of the heart or in a threedimensional myocardium.…”

Current Distribution Identification in Fuel Cell Stacks From External Magnetic Field Measurements

“…This technique is already well known and has provided many interesting results in different research fields. For instance, let us mention the reconstruction of currents density in circuit breakers [1], in bus-bars [2] and even in the human heart [3]. In this work, we focus on the application of this technique to fuel cell stack.…”
