High path loss and
availability of wide bandwidth make mm-waves an ideal candidate for short
range, high data rate transmission for wireless MRI applications. The proposed
system uses a custom designed integrated chip (IC) radio that uses mm-waves (60
GHz) as the radio frequency carrier. We report link tests up-to 500 Mb/s for distances up-to 50cm in the MRI bore. The addition of time division multiplexing
(TDM) circuitry allows multiple wireless links to be created simultaneously
with minimal inter-channel interference. This leads to a highly scalable, low-power solution for wireless MRI.
