FerrAlert Halo - Ferromagnetic Detection Systems

Normal MRI Picture / MRI Picture w/Ferrous Hair Clip

FerrAlert Halo PreScreen:

The FerrAlert Halo PreScreen is set to a very high sensitivity to detect objects as small as a hairpin. This unit is typically placed in a dressing room or the interview/screening area. It requires no breach of the patient or staff intimate personal space. If an object is detected the operator will be Alerted by a visual and audio alarm.

Unlike other types of detectors, FerrAlert Halo PreScreen emits no electromagnetic radiation to detect objects. Titanium. plastic, wood, copper, aluminum and all other non-magnetic materials not attracted to the magnet will be ignored.

When the GREEN HALO array of READY indicator lights located in the vertical columns of the portal are illuminated (ON), the system is ready for detection of ferromagnetic objects.

With the GREEN READY indicator lights ON, pass thru the portal. If a ferromagnetic object is detected, an AUDIO ALARM will sound, The GREEN READY HALO indicators lights will extinguish and the AMBER LOCATION indicator lights will illuminate.

The location of the ferromagnetic object in the Sensor Portal is indicated by the illumination of the group of 4 or more amber LED's closest to the ferrous object. For example as shown in the picture to the left, if the second from the top, left and right groups of LED's (amber) are activated, the ferromagnetic object is near the center of the portal at head level. If multiple groups of amber LED's are illuminated, a number of sensors have been activated.

FerrAlert Halo Entry:

The FerrAlert Halo Entry is used to detect items as small as a pocket knife that may be brought into the scanning room.

Like the FerrAlert Halo Prescreen the FerrAlert Halo Entry emits no electromagnetic radiation to detect objects. Titanium. plastic, wood, copper, aluminum and all other non-magnetic materials not attracted to the magnet will be ignored.

When the GREEN HALO array of READY indicators lights located in the vertical colums of the protal are illuminated (ON), the system is ready for detection of ferrous objects.

With the GREEN READY indicator lights ON, pass thru the portal. If a ferromagnetic object is detected, an AUDIO ALARM will sound (at the portal and operator's display module), The GREEN READY HALO indicators lights will extinguish and the AMBER LOCATION indicator lights will illuminate.

The location of the ferromagnetic object in the Sensor Portal is indicated by the illumination of the group of 4 or more amber LED's closest to the ferrous object. For example as shown in the picture to the left, if the second from the top, left and right groups of LED's (amber) are activated, the ferromagnetic object is near the center of the portal at head level. If multiple groups of amber LED's are illuminated, a number of sensors have been activated.

The NIGHT ALARM switch should be turned ON when there are no MR personnel present.

Why FERRALERT

REDUCES THE RISK OF INJURIES AND DEATH
Although existing safety recommendations to prevent accidents are comprehensive, human error still occurs, resulting in injuries or even death to patients, staff and visitors. With increasing magnet field strength and steeper field gradients, the risks are increasing

PREVENTS QUENCHES AND RAMP DOWNS
Quenches can cost up to $500,000 in service and repair cost per occurrence. Lost income during magnet downtime can result in additional $ 200,000

REDUCES OPERATING COSTS
FERRALERT™ yields a rapid return on investment and pays for itself by prevention of damage to a magnet as well as support equipment. Imaging downtime can cost $ 1,200 to $ 3,000 an hour. The lost imaging time to remove a missed cell phone, for example, from a magnet or to remove a patient because of a missed ferrous object can add up over time and easily pay for FERRALERT™

TARGETS ONLY FERROUS OBJECTS
Unlike conventional metal detectors which detect many different metals, FERRALERT™ alarms ONLY upon detection of ferromagnetic metals, and helps to pinpoint the location of an object.
