Mayo clinic's compact 3T scanner

This is the world's smallest 3T head scanner capable of 80 mT/m gradient performance. Locally known as MR55, this is now one of the many MRI scanners used in Mayo Clinic for human brain studies. The blue and red tapes on the floor indicate 100 G and 300 G, respectively, indicating how fast the magnetic field falls off away from the scanner. These pictures were taken on Dec 17th, 2021, when the scanner was undergoing a scheduled upgrade.
