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.
