When designing RF coils, some key aspects need to be considered. One of the most important aspects is that the Tx coil should have excellent B 1 homogeneity, while the Rx coil should have excellent sensitivity. Hence, for Rx coils, elements need to be close to the region of interest (e.g., the spinal cord).

Do not move too quickly; this could cause the material to fall off the forks or damage the pallet (and material too). When moving the coil, the outer wraps of the coils should be secured tightly with tape or banding. Never lift or drag a stack of coils as a unit. You should always only move them one at a time.
