This work compares the performance of two commercial RF coils with a new transmit-array hybrid coil developed at NeuroSpin for the human head at 7T. This z-segmented coil uses 11 transceiver dipoles connected to 7 power channels via an SVD-box, one transceiver patch to cover the top of the head, and 10 receive-only 3D loops in-between the dipoles. Its performance outbeats that of the commercial coils both in terms of signal-to-noise ratio and dynamic RF shimming efficiency.
