Overview

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.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
