MetalMag for MRI Safety Screening

MetalMag incorporates the benefits of magnetometers and metal detectors, allowing a rapid analysis of the patient in the search for any ferromagnetic metal objects while discriminating objects such as prostheses and implants that are not dangerous in the MRI environment.


MetalMag for MRI Safety Screening - detail

Free-Standing Design Does Not Require Structural Modifications for Installation or Deployment

The CEIA MetalMag is designed to provide a better approach to MRI safety screening. In today’s MRI environment, there is little time for distractions. Safety screening is important for patients and staff and should be simple, fast and highly effective every time.
No guesswork. True, intelligent alarms. That is the CEIA standard!

Detection Features

  • The capability to detect the full range of MRI safety threats, according to the sensitivity level selected.
  • Quick, accurate analysis of all the parts of the body for the individual in transit.
  • 60 pinpointing zones with high resolution and precision: ∂ 20 vertical, 3 Lateral.

Unmatched Throughput

  • Leading-edge discrimination technology allows safe items to automatically be filtered, including standard eyeglasses and underwire bras.
  • No need for specialty metal-free clothing or stringent operating procedures.
The MetalMag discrimination technology allows it to process MRI staff and patients quickly as they enter and exit the MRI zone III area, utilizing proprietary filtering algorithms to eliminate unnecessary alarms.
The zone target identification provides the MRI staff with the location of the area where the item has been detected for quick removal or immediate recognition. Screening performed upon a single transit, no need for subjects to spin or make multiple passes.

Unique Alarm Signaling

  • Flexible acoustic alarm signaling system for staff -friendly environment: 34 Unique Sounds; 10 Continuous and Pulsed Tones.
  • 4 multi-zone display bars, each programmable as entry Stop/Go and/or local alarm indication.
  • High visibility of the control unit and zone indication, independent from the operator position and the installation environment.
  • Optional remote indication of detector operation.
Accurate signaling is essential for best operation and flow management. The MetalMag provides the user with fully-programmable signaling. Both entry-points can indicate with a high level of accuracy, even simultaneously, the vertical and lateral areas of transit of the threats detected, and can also be configured as traffic lights to control transits through the detector.
