16-channel head coils using a variety of RF resonators
were tested on study participants at 3 Tesla, and the
penetrated RF magnetic fields were compared amongst four
different RF resonators in a spherical phantom. we
proposed using a 16-channel coil with a SIR with four
arms, and we compared it to other RF resonators based on
microstrip transmission lines. The 16-channel coil
provided better B1+ fields and can be effectively
controlled for parallel imaging in 3 Tesla MRI systems.
16-channel head coils using the SIR with four arms for
parallel imaging could be used in hospitals for higher
quality imaging.
