AIRC 3T Instrument


The Siemens 3T Prisma instrument, installed in August 2016, represents a significant upgrade to the AIRC 3T Tim Trio instrument installed in 2006. The gradient set has a Gmax of 80 mT/m and utilizes a force balanced design, which provides a quieter scanning environment. The RF architecture is now fully digital with optical fiber links supporting a total of 64 receiver channels and parallel transmit. 

The AIRC Prisma upgrade was possible with funding from the NIH and institutional support.
