<unk>  (MFI) is a non-invasive and side-effect-free cardiac diagnostic method. In more recent technology,<unk> ardiography (MCG) has become the clinically predominant application for recording the heart's<unk>  signals. that detects and records the electromagnetic signals that are associated with the heartbeat using a multi-channel<unk>  sensor array. The electric signals are known from the ECG. In the 1990s and beyond, more recent technology has supplanted the MFI, particularly MCG (xref. Cardiomag Imaging, Inc.). Through clinical research in Europe, Asia, and the U.S. (see publications in footnotes), MCG has been proven to have practical application for diagnosis of cardiac disease, and has become the clinically predominant application for recording the heart's<unk>  signals. In comparison to MCG, MFI, among others, records the whole relevant area above the chest of the person.
