Ferromagnetic Detection System, Pre-Screening and MRI Entry
Pre-screening System FerrAlert™ HALO PRESCREEN is a highly sensitive patient and personnel screener that detects VERY SMALL ferrous objects down to the size of a typical hairpin. It is up to 25 times more sensitive than our FerrAlert™ HALO ENTRY detector. The recommended placement for this device is in the patients’ screening or locker-room area, away from the magnet room. This product helps increase patient throughput and avoid potential misdiagnosis. It is also very useful in screening staff from other departments who are visiting the MRI area. OPERATION: When the GREEN HALO array of READY indicator lights, located in the vertical columns of the portal are illuminated (ON), the system is working. If a ferromagnetic object is detected, an AUDIO ALARM will sound, the GREEN READY HALO indicator lights will extinguish and AMBER LOCATION indicator lights will illuminate. The location of the ferromagnetic object in the Sensor Portal is indicated by an illumination of the group of amber LEDs closest to the ferromagnetic object. For example, if the top left amber LEDs are activated, the ferromagnetic object is near the left side of the portal at head level. SPECIFICATIONS: MEDICAL POWER SUPPLY: 100 TO 240 volts AC, 47 to 63 Hz, 50 VA Size: Length 5.75”, Width 3.0”, Height 1.75” AUDIO ALARM: In portal. Adjustable volume MOTION DETECTOR: Activates unit when moving object approaches portal. Adjustable activation distance SENSOR ARRAY PORTAL: Height 83”, Depth 2”, Width Adjustable: 19” to 29” inside dimensions; 23” to 33” outside dimensions Pre-Screening System 24" Portal Width
Can be easily and quickly installed without disrupting patient care or imaging schedules
Optional Swingaway mechanism for facilities with limited floor space Entry System FerrAlert™ HALO ENTRY – Ferromagnetic Detector complies with ACR and JCAHO standards to protect the magnet room against moderate to large size ferromagnetic projectiles. The device can be installed freestanding at the approach to the MR magnet room, or unobtrusively onto the door frame outside or inside the magnet room, depending on the swing of the door. This product significantly helps to protect the investment in the magnet and to avoid a catastrophic accident. FerrAlert™ HALO ENTRY has been certified by Siemens Medical Solutions for installation and use inside the magnet room for both 1.5T and 3.0T MRI magnets. OPERATION: When the GREEN HALO array of READY indicator lights, located in the vertical columns of the portal, are illuminated (ON), the system is working. If a ferromagnetic object is detected, an AUDIO ALARM will sound at the portal (and operator’s display module, if required). The GREEN READY HALO indicator lights will extinguish and AMBER LOCATION indicator lights will illuminate. The location of the ferromagnetic object in the Sensor Portal is indicated by an illumination of the group of amber LEDs closest to the ferromagnetic object. For example, if the bottom left amber LEDs are activated, the ferromagnetic object is near the floor on the left side. The NIGHT ALARM switch on the optional OPERATOR’S DISPLAY MODULE should be turned ON when there are no MR personnel present. SPECIFICATIONS: MEDICAL POWER SUPPLY: 100 TO 240 volts AC, 47 to 63 Hz, 50 VA Size: Length 5.75”, Width 3.0”, Height 1.75” AUDIO ALARM: In portal and in operator’s display module. Adjustable volume MOTION DETECTOR: Activates unit when moving object approaches portal. Adjustable activation distance SENSOR ARRAY PORTAL: Height 83”, Depth 2”, Width Adjustable: 42” to 52” inside dimensions; 46” to 56” outside dimensions Entry System Adjustable Portal Width from 42 inches to 52 inches inside dimensions, and 46 inches to 56 inches outside dimensions, 83 inches High and 2 inches in depth.
