The use of dielectric pads substantially improves
transmit homogeneity in the thighs. However, it
compromises the receive homogeneity of the body coil. If
uncorrected, this can degrade image quality when using
parallel imaging techniques which rely on body coil
information for calibration purposes. A correction
procedure using prior knowledge of the body coil
reception profile confirms this effect and restores
image uniformity.
