ONPRC 3T Instrument

Description

The Siemens 3T Prisma instrument is located on the campus of the Oregon National Primate Research Center (ONPRC; 10 miles west of OHSU's main Marquam Hill campus) in a dedicated 2500 ft2 building that includes animal preparation areas and offices.  The radio frequency (RF) transmitter unit contains one 35 kW narrowband (1H) RF transmitter and one 8 kW broadband RF transmitter capable of producing 20‑128 MHz.  The instrument is equipped with a SONATA gradient coil set and a CASCADE gradient amplifier (2000V/500A onall three axes).  Together they are capable of producing field gradients of ≥40 mT/m, with a slew rate of ≥200 T/(m*s), on all axes.
