Spatiospectral Description of Current Dipole as a Source of the Magnetic Field of the Heart

In practice, the experimenter works with input superconducting transducers, the design of which in biomagnetic systems depends on the research conditions, magnetic shielding, cryogenic support, the required sensitivity to magnetic field induction, and the technological capabilities of the developers. It is impossible to compare the results of studies obtained for different biomagnetic systems. The problems of describing the source of magnetic field of the heart on the basis of spatial-frequency transformations of a 2D model of the current dipole are considered. The depth, location, and orientation of the current dipole on the value of magnetic field induction and its spectrum over the space of the scale for measuring the magnetic field of the heart are studied.
