Abstract
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.
