Magnetic Resonance Imaging (MRI) is a medical imaging technique used in radiology to investigate the anatomy and function of the body in both healthy and diseased states. MRI scanners use strong magnetic fields to form images of the body. The technique is widely used in hospitals for medical diagnosis, staging of disease and for follow-up without exposure to ionizing radiation.

As world experts in the field of magnetic detection, Metrasens has developed the award winning range of Ferroguard® ferromagnetic detection products.  When ferrous objects reach the MRI magnet's fringe field they can be strongly attracted, at high speed, towards the magnet's core. This is known as the projectile effect.  Ferromagnetic objects taken through the MRI door can lead to serious injury, unplanned MRI restarts or MRI damage.

Statistics show an increase in projectile incidents

185% increase in adverse MRI events over the last five years.

389 MRI related events – including 9 deaths, occurred in the last 10 years, with 10% of these events reported as projectile-related. 

Metrasens approached GX Design to work on a range of sophisticated sensor modules that form part of a new generation MRI safety system.  These sensors allow the new Ferroguard product to significantly ease MRI staff workflow around the door while maintaining highest safety levels.
