Self-Decoupled Asymmetric Saddle Coil Array for SENSE Imaging

The quest for lower g-factor and higher reduction factor for a SENSE-optimized coil array often results in a trade-off of lower intrinsic SNR for higher SENSE SNR due to the non-overlap nature of the adjacent coils. In this paper, we present an asymmetric saddle (Asaddle) coil array with each of its Asaddle coils having one wing significantly smaller than the other and being able to decouple from its adjacent Asaddle coils without overlap. The Asaddle coil array not only can preserve the intrinsic SNR as a conventional array but also can provide significantly lower g-factor than the conventional array.
