RF-coil design for combined electrophysiology and fMRI
in non-human primates is challenging because any coil
design needs to be sufficiently open to allow for
electrode access to the brain. Patch antennas allow for
a more open design, but since our bore is too small for
a 300 MHz traveling wave, we developed an open
quadrature transmit coil/antenna placed in-situ. The
transmit coil/antenna is capable of producing a
sufficiently homogenous B1 field. This device can be
used alone in transceiver mode or in combination with
dedicated receive arrays which allow for maximum
flexibility while maintaining a very high SNR.
