EMI FILTER FOR HIGH-FIELD MRI SYSTEMS AND SENSITIVE IMAGING PROCESSES FROM EMIS
PROVIDE SUPPRESSION OF UNWANTED SIGNALS OVER A WIDE FREQUENCY RANGE UP TO 10GHZ.
Global EMC solutions provider EMIS announces the availability of the MF420-2CF-M MRI Filter, a specialised electrical filter for use in Magnetic Resonance Imaging rooms to block unwanted electromagnetic interference( EMI) and radiofrequency interference( RFI) from entering or leaving the MRI environment.
Designing or selecting an EMI filter for high-field MRI systems is very different from general electronics filtering as MRI environments are extremely sensitive to RF noise and require shielded-room integrity as well ultra-high attenuation across wide frequency bands.
EMI filters are critical in MRI High-field systems which operate with very low-level RF signals in an environment featuring strong static magnetic fields. External EMI contamination can degrade signalto-noise ratio, create artifacts in images and cause regulatory non-compliance. Even cables entering the MRI room can act as antennas and leak noise into the shielded enclosure.
