Abstract

A multicoil phase-alignment technique is demonstrated for high-speed and bandwidth-intensive applications. Signal-to-noise (S/N) profiles of both the hardware and software implementations show a two to three-fold S/N increase compared to the standard body coil, and EPI experiments using the hardware version show a similar image quality improvement at bandwidths ranging from ±15.625 to ±125 kHz. Both versions provide a significant reduction in reconstruction requirements compared to the standard `sum of squares' method. Phantom and in vivo EPI experimental results suggest that the technique is useful for high speed and continuous volumetric imaging, offering improved S/N and reduced reconstruction requirements.
