Prisma 3.0T

The PRISMA platform is notable for 64 independent RF channels.  It has an 80 mT/m gradient set combined with a 200 (T/m/s) slew rate, enabling superior diffusion white matter tracking.  The RF allows for modern parallel acquisition strategies such as multiband, simultaneous multi-slice imaging.  What is more, there is parallel transmission of RF that allows for inner volume imaging (imaging a field of view smaller than the object without aliasing). The PRISMA also employs advanced homogeneous image intensity and shimming functions. There are 2 head coils with the new system; a 32 channel head only and a 64 channel head\neck combo.
