Magnetometric Investigations of Biomagnetic Signals: Magnetocardiography

Nonlinear analysis of biomagnetic signals recorded from uterine myomas

OBJECTIVE To determine if there is any non-linearity in the biomagnetic recordings of uterine myomas and to find any differences that may be present in the mechanisms underlying their signal dynamics. METHODS Twenty-four women were included in the study. Sixteen of them were characterised with large myomas and 8 with small ones. Uterine artery waveform measurements were evaluated by use of Pu...

Biomagnetic methodologies for the noninvasive investigations of the human brain (MAGNOBRAIN).

Magnetoencephalography (MEG) non-invasively infers the distribution of electric currents in the brain by measuring the magnetic fields they induce. Its superb spatial and temporal resolution provides a solid basis for the 'functional imaging' of the brain provided it is integrated with other brain imaging techniques. MAGNOBRAIN is an applied research project that developed tools to integrate ME...

MgB2 SQUID for Magnetocardiography

Biomagnetic research in gastroenterology

Humans rely on their gastrointestinal system for providing the body with a constant supply of nutrients, water and electrolytes. The food must be digested (reduced physically and chemically to a molecular level) to be absorbed in the small intestine. Since both digestion and absorption depend on diffusion the flow of nutrients along the small intestine (GI transit) must be compatible with the r...

Multichannel Squid Biomagnetic Systems

The field of biomagnetism advanced considerably since the first recordings of magnetic fields of the human heart in 1963 and of the human brain in 1968. Since the introduction of whole-cortex magnetoencephalography (MEG) systems in 1992, the number of installed channels has dramatically increased, and the magnetic evaluation of the human brain has been gradually finding its place in clinical wo...
