A realistic torso model for magnetocardiography
The International Journal of Cardiac Imaging, 1991This paper contains the description of an inhomogeneous, multi-compartmental volume conductor model which is in use in our group. Although initially developed for the study of the ECG, it has been found to serve equally well for simulating the magnetocardiogram (MCG), the forward problem, and as a basis for source analysis of the MCG, the inverse ...

Standardization of magnetocardiography in nonhuman primates
Physics in Medicine and Biology, 2008To establish the electrophysiological mappings of nonhuman primates by using magnetocardiogram (MCG) data and obtain the normal values of MCG parameters, we used 64-channel superconducting quantum interference devices to measure 8x8 MCG data for 95 cynomolgus monkeys (Macaca fascicularis, 51 female and 44 male).

Capability and Limitations of Electrocardiography and Magnetocardiography
IEEE Transactions on Biomedical Engineering, 1972The capabilities and limitations of electrocardiography and magnetocardiography are discussed. Representing the electrical activity of the heart by an impressed current density ji, electrocardiography determines the spherical harmonic multipole expansion of its divergence (flux source), while magnetocardiography determines the spherical harmonic ...

New Trends in Clinical Magnetocardiography
2000Magnetocardiography was introduced to clinical cardiologists in the early 1970’s. The measurement devices were technically unreliable, signal-to-noise ratio was poor and measurements were time consuming. Most measurements were performed in ambient environment without any shielding.

Solving the inverse problem in magnetocardiography
IEEE Engineering in Medicine and Biology Magazine, 1994Biomagnetic methods have proven to be valuable as research tools in obtaining functional information that is difficult to gain by conventional clinical imaging methods. Still, the magnetocardiographic localization method has to compete with corresponding bioelectric measurements and other noninvasive methods, such as two-dimensional echocardiography ...

Comparative capabilities of electrocardiography and magnetocardiography
The American Journal of Cardiology, 1972The readers of the paper by Cohen and McCaughan in this issue of the Journa1,1 particularly those new to magnetocardiography, will undoubtedly raise 2 vital questions. First, “Is magnetocardiography, in principle, different from electrocardiography ?” and second, “Can magnetocardiography provide clinical information that is not obtainable in ...
