Wireless links have been proposed to connect MR array receiver coils to the rest of the system to eliminate the safety and crosstalk issues of current coaxial cables. However, the limited data rates supported by wireless links restrict the number of coil channels that can be transmitted to well below those of the state-of-the-art high-density arrays that would benefit the most from wireless technology. In this work, two independent methods of compressing MR data prior to transmission are simulated that when combined can readily reduce it to 1/3 or less of the original amount with negligible impact on image quality.
