Enhanced Low Frequency MRI using Flexible Shape Arrays Made of Standard Wire

Abstract

Flexible coil arrays are increasingly popular in magnetic resonance imaging (MRI), due to their superior anatomical fitting and patient comfort. Several coil concepts have been proposed, using self-resonant structures for the implementation of the detecting coils. In this work, we show that flexible coil arrays can be implemented in a simpler way, using standard flexible copper wire, as long as the decoupling between elements is kept high. The design approach proposed here can be extended to any frequency, and an example of a 7-channel array for 13 C at 3T (32.1 MHz) is shown, where an SNR increase is obtained for a human head phantom, compared to state-of-the-art traditional coils.
