| Abstract: | A new interface combining phased arrays and echo-planar imaging (EPI) technologies was developed for two channel breast MR
EPI applications. A detailed design for a dual-channel. EPI-compatible, phased array breast coil is described. EPI digital
data multiplexing, signal controlling and sampling schemes are also presented. Results from breast phantoms and patients demonstrate
a 55% improvement in signal-to-noise ratio when compared to a conventional two-loop, single channel coil conliguration. This
method can be easily expanded to a four or more channel. EPI-compatible, phased array system to improve field-of-view coverage
and signal-to-noise ratio. |
