Figure 3. Average SNR of the single coil element vs the diameter of the RF shield at 14 T.

Figure 3.

A similar behavior was observed both when the coil was close-fitting (a) or moved 20 mm away from the head model (b) to reduce the perturbation due to the head. In the latter case, the smallest shield diameter was increased to 325 mm to enclose both the coil and the sample at the isocenter. SNR was normalized by its maximum value for each plot independently.
