Abstract
An ultra low output impedance RF power amplifier for driving a multiple transmit coil Magnetic Resonance Imaging (MRI) system is described, comprising an output matching network with high power MOSFET operatively coupled to at least one transmit coil in the MRI system for a desired output power and impedance. This invention also describes a method for achieving decoupling using the RF power amplifier to drive at least one transmit coil.
