4.7 Tesla 33 cm MRI/S System

4.7 Tesla 33 cm MRI/S System. 4.7 Tesla 33 cm MRI/S System.

This instrument is located at the MagLab's AMRIS Facility at the University of Florida in Gainesville.

This active-shield horizontal magnet is equipped with an Agilent Direct-Drive 4-channel console running vnmrj 3.1a. This is a dedicated animal MRI system and a workhorse for animal model studies such as muscular dystrophy, drug additions, epilepsy, and tumor models, etc. Capabilities of dissolution DNP technology for in vivo animal models are available to external users through the MagLab.
