| Mobile MRI - Keeping Magnet Cold |
Will,
When a mobile MRI Scanner is in motion going from site to site a "ramp down" is performed before moving.This is when the magnetic field is lowered but not completely shut off. The field still keeps it's integrity due to the Cryogens that surround it. When it comes to the new site, a "ramp up" is performed to bring the magnetic strength back up to par. Bottom line...The Cryogens are not boiled off and keep the magnet cold when it is motion. If the magnet were to suddenly lose it's power, it could be due to a cryogen boil off.
