Overview
Overview
abstract
An MRI system includes an array of series resonant transmit elements 6 and 65 including individual control of RF current in all elements 106, 108, 110, 114, 116, 118, 120. The array 6 and 65 adjusts scan homogeneity during a scan or prescan phase by adjusting amplitude and phase. The array 6 and 65 also selectively excites areas of interest, thus avoiding major power dissipation and avoiding heating in the patient.
