Simultaneous MR data acquisition with multiple mutually desensitized RF coils

摘要

A method for the simultaneous acquisition of data from two transmit/receive "birdcage" coils is described. The coils are individually RF shielded, making them insensitive to signals generated outside of each coil's volume. Each coil is designed for imaging one leg, and when used together, both legs are imaged simultaneously. In coronal or axial orientations, a small FOV around each leg can be imaged without aliasing. This results in a two-fold scan time reduction compared to a large FOV acquisition with the same spatial resolution.
