We present an integrated system for 7T ex vivo imaging
that meets several of the challenging design
requirements needed to image a whole ex vivo brain at
100um isotropic resolution in 25 hours of averaging
time. It incorporates a 31 channel receive array, an
improved mechanical design, preamps mounted at the coil
detectors, and an extended transmit coil design capable
of producing high-power pulses. This new design
substantially increases the range of ex vivo imaging
applications.
