The Most Comprehensive & Reliable MRI Safety Solution
Precision Ferromagnetic Detection Systems
Identify and stop ferrous materials from inadvertently entering the MRI zone. Prevent serious injury to patients, staff, and equipment.
Supports ACR, Joint Commission, FDA, AAMI, FGI, and VA safety recommendations.
FERRALERT™ allows technologists to quickly locate and remove ferromagnetic threats with no invasive searching, pat-downs, or personal contact required.
Shows exact location of ferrous object.
Advanced intelligent visual warning.
Fewer false alarms.
Patented technology.
Ferromagnetic Detection Systems (FMDs) significantly enhance safety standards and protect patients and staff from potential incidents, which have increased in recent years.
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.
Ferromagnetic Detectors - MRI Safety Equipment
Screening for ferromagnetic materials by direct inspection and the use of an FMD. Kopp Development has been the leading manufacturer of Ferromagnetic detectors for MRI safety.
MAGNET ENTRANCE CONTROL

KOPP FerrAlert™ Halo II Plus
Guards the entrance into the MRI exam room preventing ferromagnetic threats from entering Zone IV.
PATIENT AND STAFF SCREENER

KOPP FerrAlert™ Solo
The most sensitive, full-body ferromagnetic scanner for MRI Safety. Install in pre-screening Zones II/ III.
HAND-HELD DETECTION

KOPP FerrAlert™ Target Scanner
Purpose-built to enhance MRI safety and complement the complete FerrAlert™ product line.
MRI ENTRANCE CONTROL- ZONE IV
FerrAlert™ Halo II Plus
Precise ferromagnetic detection at the Zone IV MRI entrance- prevents serious projectile related injuries and costly damage to MRI equipment. Intelligent visual warning eliminates nuisance alarms triggered by routine door movements.
-
Reliable detection of ferromagnetic threats heading toward the magnet
-
Intelligent visual and STOP™ voice alarms with escalating alerts
-
Reduces nuisance alarms and alarm fatigue, acoustic alarm only activated when the body heat sensor detects a human
-
Flexible installation for various MRI room layouts
-
Supports compliance with FDA, ACR, AAMI, Joint Commission, FGI, and VA recommendations
PATIENT & STAFF SCREENER- ZONES II/III
FerrAlert™ Solo Detector
The most sensitive, full-body patient and personnel scanner available to MRI providers. Install in the controlled pre-screening zone.
- Pinpoints location: Allows techs to quickly and easily identify & remove the threat.
- Self-screening: Supervised and self screening is consistent, unambiguous and simple.
- No-touch activation: Safeguard against dangerous cross-contamination.
THREAT DETECTION, LOCATION, RECORDING, & ANALYSIS
FerrAlert™ Encompass
Automated ferromagnetic detection and documentation at the MRI magnet room entrance, helping facilities strengthen Zone IV safety and simplify compliance.
-
Automatically detects and logs ferromagnetic threats entering Zone IV with a continuous photographic record
-
Captures potential and actual projectile events, recording images before, during, and after entry into the MRI room
-
Generates clear, inspection-ready reports to support The Joint Commission incident documentation requirements
-
Enhances MRI safety and accountability with hands-off, always-on monitoring
HAND-HELD FERROMAGNETIC DETECTION SYSTEM
FerrAlert™ Target Scanner
The only true handheld ferromagnetic detection system available, purpose-built to enhance MRI safety and complement the complete FerrAlert™ product line.
-
Ideal for enhanced patient screening, especially for non-ambulatory patients or those unable to complete MRI safety questionnaires
-
Portable, practical, and easy to use, providing flexible screening wherever it’s needed
-
Accurately distinguishes ferromagnetic from non-ferromagnetic materials to help identify potential hazards
-
Operator-dependent, yet highly effective when used properly—like all handheld detection tools
2024 ACR Manual
RECOMMENDATION*
-
Permanently installed FMDS have demonstrated to be effective as adjuncts to the MR Safety screening process.
-
Patient Screening FMDS: at a distance from entrance to Zone IV (typically Zone II to III). For screening of ambulatory patients/subjects
-
Entryway FMDS: Final ferromagnetic check immediately before entering Zone Iv
-
-
FMDS should be optimally sited in Zone II and Zone III depending on the workflow of the facility
-
Handheld FMDS: Can be helpful to screen non-ambulatory patients if onMR Conditional transport equipment. pg 130**

RECOMMENDATION
-
“Placing a ferromagnetic detector with an audible alarm at the magnet room door.. provides an additional level of safety when the technologist is not facing an open magnet room door.”
