Validation of a Magnetic Sensor in Arterial Flow Recording, Compared With the Reference Method, at Various Peripheral Arterial Sites

Recruiting now · Not applicable

Conditions studied: Lower Extremity Artery Disease

In brief

The measurement of magnetic fields emitted by cardiac activity has already been studied in magneto-cardiography. To date, however, this technology has never been evaluated in the peripheral circulation. The magnetic susceptibility of iron in the circulating blood and the ionic currents in the blood stream generate a very weak induced magnetic current, which can be detected by the micro-sensor of the prototype investigators wish to study. Proving the validity of this prototype would make it a new diagnostic and even prognostic tool, non-invasive, less costly and more accessible than Doppler for screening peripheral arterial disease.
