In this study we are comparing 16 channel TEM, 8 channel TEM
and 8 loop array pTx body coils based on experimental data obtained from full
scale whole body prototypes as opposed to only simulation. Besides SAR,
efficiency and uniformity, there are additional criteria to include when
selecting a body coil for parallel transmit. Examples are star intensity
artifact, E fields that heat up cables and baluns, VSWR, and perturbation
sensitivity, which may make it impossible to build a certain design given
obtainable tolerances.
