FerrAlert SOLO
The FerrAlert SOLO is present both at 3T & 7T MRI control rooms.
The FerrAlert is a high sensitivity, full-body patient and personnel screener. It can pinpoint out the location of ferromagnetic objects up to the size of a hairpin. This will allow you to identify and remove any ferromagnetic objects carried by the participant.
Instruction on how to use the FerrAlert Solo are shown in the figure FerrAllert SOLO.

FerrAlert Halo II
The FerrAlert Halo II is present at the 7T only
FerrAlert™ Halo II guards at the entrance into the MRI exam room. It provides detection and prevention of ferromagnetic threats from entering the scanner room. The FerrAlert will give a warning when a ferrous object approaches the scanner room. The greater the threat, the further away the pre-warning is activated. This will first be a YELLOW LIGHT at the top of the Halo. Followed by FLASHING RED LIGHTS when a large ferromagnetic object is approaching the portal. The Halo will go into Alarm Mode when the infrared beam at the bottom of the halo is interrupted. If a thread is detected at this stage, an AUDIO ALARM will go off combined with RED LIGHT at the location of the threat will be activated.
