Microwave Link Testbed PCB for Wireless MRI
The data link implementation is a major challenge of wireless MRI. Ultra-wide band (UWB) microwave short-range serial links seem to be a good fit and present many advantages, so further investigation/prototyping is needed. Therefore, we designed and developed an FPGA Microwave Link Testbed for Wireless MRI.

+ High bit rates (possible at carrying
frequencies >3Ghz)
+ Less directional antenna (than MM-Wave)
+ Needs only about 150mW (x30 less than WiFi)
+ Wireless interfaces distributable around the
array (avoiding the data cable bottleneck
implicit in the WiFi approach)
+ Non-magnetic, simple, small components
+ The larger data recovery components have
no need for miniaturization and employ commercial ICs
The implementation of data links is a significant challenge for wireless MRI, with ultra-wide band microwave short-range serial links offering advantages such as high bit rates, less directional antennas, low power consumption, and non-magnetic components. An FPGA Microwave Link Testbed was designed and developed to further investigate and prototype this technology.
