The feasibility of human head imaging
at 10.5T is demonstrated by the successful acquisition of in vivo porcine head images. This is achieved with an 8-element
end-loaded dipole array resonant at 10.5T (447MHz). This dipole array is
compared in terms of transmit efficiency and signal-to-noise ratio to a
high-pass birdcage coil and loop array at 3T, 7T, and 10.5T. All coils share
identical dimensions and element count. While both transmit arrays have
comparable SNR performance at 7T, the dipole array is inferior in terms of
transmit efficiency compared to the loop array and birdcage coil at all field
strengths examined.
