Abstract
Magnetocardiography (MCG) is a method of measuring magnetic fields generated by electrical activity of the heart using extremely sensitive devices such as superconducting quantum interference devices. One of the advantages of MCG is the possibility of forming magnetic field distribution maps over the chest, to which mathematical methods of analysis and classification can be applied. The paper describes the method of current density distribution maps classification, obtained using MCG, based on correlation analysis. In the experimental part, 2142 current density distribution maps of 247 patients were used. Using the proposed method, it the accuracy of classification in 95% was achieved for the case of parting all maps to 14 classes that correspond to a certain state of the cardiovascular system.
