Abstract
A Class-E amplifier has been adapted for use in the radio frequency section that drives a transmit coil of a magnetic resonance imaging (MRI) system. The Class-E amplifier responds to a radio frequency carrier signal and a control signal by producing a radio frequency excitation signal for driving the transmit coil. The Class-E amplifier includes a pickup coil that senses a signal emitted from the transmit coil and produces a feedback signal that is used to alter the control signal and thereby control production of the radio frequency excitation signal.
