Comparative Study of Magnetocardiography and Emission Computed Tomography.

"Magnetocardiography (MCG) is a non-invasive, risk-free, and contactless technology that characterizes the local magnetic field signals generated by the electrical activity of the heart.~the magnetic signals used in magnetocardiograms can pass through the body with almost no interference. Therefore, magnetocardiography theoretically offers more clinically useful information, with the advantages of being non-invasive, safe, and fast, enabling earlier and more accurate diagnoses of potential heart diseases."
