MRI scanner

An Agilent 7/310 (7.0Tesla, 310mm bore) (Walnut Creek, CA) NMR/MRI scanner is housed adjacent to the FMRI laboratory.  This system is actively shielded, cryo-cooled and offers a 4-channel, phased array for reception and an additional modular transmitter channel for up to a four transmit channels.

A complete description from Varian (now Agilent) is  Here


Three gradient inserts are available with the following specifications :

Inner Diameter (mm) Strength mT/m
115 60
205 120
305 210

RF probes

A wide array RF coils are available to the users for both Proton and Phosphorus imaging.  These include three bird cage design quadrature coils, a millipede coil, three mult-band surface coils.  Two SwiftLite animal holders are available for mice and rat imaging.
