Ensure your non-ambulatory patients are protected

The majority of MR Conditional patient transfer equipment contains residual ferrous material, making it incompatible with high sensitivity FMDS.

Ferroguard Assure
  • Trustworthy detection and clear, simple alerts
  • Lowest probability of alarm fatigue
  • MRI-Safety-Manager, providing you with: Oversight, Education and Analytics

So much more than just another FMDS


  • Comprehensive tools to enable you to stay safe and a simple management system to demonstrate compliance to regulatory bodies

    Ferroguard Assure's MRI-Safety-Manager provides you with real-time oversight of magnet room door status, ferromagnetic activity and Zone IV entries. The only system enabling you to categorize "ferromagnetic objects unintentionally entering the MRI scanner room" (as required by JCAHO 2015 accreditation standards) with fast and meaningful reporting. All backed up by always available MRI safety education for your team, provided by a leading faculty.

  • Confidence your FMD will do its job, when it really matters

    Ferroguard Assure is always on, always detecting. With other FMDS, design-limitation detection gaps may allow significant risk items to pass undetected into Zone IV. With Ferroguard Assure there will be no sensor activation delays on door opening, no slow-reset delay following an alert. Always on, always detecting, always ready for those few seconds when your safety depends on it.

  • Always detecting BEFORE, not BEYOND the door

    Ferroguard Assure is always mounted in Zone III, even with outswing magnet room doors. An FMD mounted inside Zone IV is simply too late to meet ACR guidance to use FMDS for screening persons and devices approaching Zone IV, and too late to prevent risks becoming accidents.

    Only Ferroguard products provide visual early warning in more than name only. Superior sensors provide detection “reach” in advance of the threshold; while the clear, eye-level traffic-light display gets the message across simply and effectively.

    Ferroguard Assure's Visual Early Warning (ViEW®) gives you time to react to prevent an accident.


  • Lowest alarm fatigue

    Alarm fatigue is consistently identified as the most serious technology-related patient safety issue.* Ferroguard Assure’s Smart Alarm has been shown to reduce extraneous audible alerts by 85%**.
    Never an alarm on exiting the room
    Never an alarm through door movement.
    Smart Alarm works with any MRI shielded door, and of course without compromising detection of risk items

  • Built to last

    Ferroguard systems are constructed from ruggedized, industrial-grade aluminum, are more than a match for the inevitable gurney collisions and will look good for years to come. With Ferroguard Assure you can keep the duct tape in the closet and avoid those annoying repair bills that typically come with other FMDS.

  • CEU-accredited training

    To ensure your team gets the best from Ferroguard Assure, every system installation is accompanied by inclusive CEU-accredited in-service training, covering MRI ferromagnetic safety and working with Ferroguard Assure.

  • The quality you expect in a patient safety product

    Ferroguard products are the only FMDS designed and manufactured under ISO9001 international quality standard; just like your MRI system, patient monitors, and probably every other medical device in your facility.

  • All-inclusive installation support

    Every MRI facility that invests in Ferroguard Assure receives our excellent installation support package:


Ferroguard should not be used to replace current MRI screening procedures. The safety of staff and patients is best served by the combination of conscientious screening protocols, thorough staff training AND installation of a ferromagnetic detection system used in the correct manner.
