A cost-effective, multichannel MRI console was developed
to exploit the potential of coil arrays and
high-bandwidth EPI acquisitions such as BOLD-fMRI. With
distributed system architecture and high-speed serial
connectivity, the console makes a digital optical
transmission approach to MRI receiver design available
at 1.5 T. The performance of an 8-channel prototype has
been demonstrated with substantial imaging experiments.
As application demands grow, this proof-of-concept
design can scale easily by adding custom-built modules.
