The most trustworthy FMD system for MRI Zone IV protection
Ferroguard Assure enhances the safety of your patients and staff while preventing costly damage to your magnet. Eliminate the risk of projectile incidents, keep ferrous objects from entering Zone IV before it’s too late. This system eliminates nuisance alarms triggered by routine door movements or when exiting the magnet room.

Metrasens is a valued partner of design and construction professionals looking to integrate FMD detection systems as part of their projects, in alignment with MRI safety best practices.

DESIGNED FOR SAFETY AND SUCCESS
Ferromagnetic Detection Systems (FMDs) to significantly enhance safety standards and protect patients and staff from potential incidents, which have increased in recent years.
Additionally, the current regulatory environment recommends the use of FMD systems and mandates them for new construction, underscoring their importance in maintaining a safe and compliant healthcare environment.
How do Metrasens FMD Systems work?
Metrasens FMD systems detect changes in the earth’s magnetic field caused by moving ferrous objects. Our technology is passive, non-emitting, and safe to use for all, including pregnant women and those with medical implants.
What specific training will be provided with our FMD systems?
You’ll receive training on use and implementation of your FMD System by Metrasens MR Safety Expert who has years of clinical experience as a MR tech, MRSO and MRSE. Training includes best practices and recommendations for improving safety in your MR suite.
“Time and time again in the pediatric population, we have been saved by these safety processes. It’s not uncommon that children have a positive ferrous detection, and we find they have eaten items that could have potentially been harmful—and parents don’t know.”
“This is a great system—we are very impressed with the quality,” says Smock. Smock appreciates the value of the forward-sensitive screenings—since other entry control systems don’t alert until after an object has crossed into Zone 4.
“This brought attention to MRI safety on a whole new level,” says Smock. “As the MRI safety officer, part of my role is to create awareness. Alarm systems help do that. They remind people that this is a magnetic environment—we can’t see it, but it’s here. Our ferromagnetic detection systems have had a huge impact on how our entire team approaches MRI safety.”
