Evidence indicates that excess RF power from coil’s associated circuitry could cause injuries to patients. Slot elements have been investigated earlier and demonstrated good potential when used for multi-channel RF coils. Here we investigate the potential of using the extended metallization of slot elements to shield stray electric field generated from RF coil associated circuitry. RF heating experiment was designed to compare the temperature of the phantom with and without using the slot’s extended metallization to shield the associated circuitry. Experimental results demonstrated an observable reduction in the phantom temperature resulting from extending the slots metallization.
