For whole brain human head imaging at 10.5 Tesla, we interlaced a 16-channel sleeve antenna transceiver with a 16-channel asymmetric dipole antenna receiver for a combined, close fitting 16-channel transmit/32 -channel receiver array. Integration of high dielectric constant material (HDC) significantly improved receiver performance in the upper brain. Simulation results indicate excellent B1 efficiency and coverage of the combined array for the whole brain imaging at 447 MHz. To further improve array performance, we developed new on-coil transmit/receive (T/R) switches capable of preamplifier decoupling. We are now in the process of building this novel closefitting 32-channel array.
