Mobile MRI - Keeping Magnet Cold
Hi
Majority of mobile MRI scanners got onboard generators.
Once you plug off scanner from main external pawer onboard generator will start automaticly.
It keeps chiler running during the transport.
Onboard generator alows you switch on the system , but I wouldn't scan using onboard generator. This is just to keep running system when power supply failure.

Mobile MRI - Keeping Magnet Cold
The chillers can be off during transport. For short trips, the boil off of cryogens will be minimal.

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.

Mobile MRI - Keeping Magnet Cold
Hello,

I'm new to the MRI modality; I've mostly worked with CT over the years.

Something donned on me today, regarding mobile MRI's. How is the magnet kept from going warm while in transport?

Thanks,

Will
