1. An ultrasound system comprising:
an ultrasound transducer configured to generate acoustic ultrasonic pulses in response to electronic driving;
a pulse circuit electrically coupled to and configured to drive the ultrasound transducer, the pulse circuit further comprising:
one or more voltage inputs configured to generate logical control pulses within the pulse circuit;
one or more high voltage power supplies configured to supply power to the pulse circuit; and
a plurality of transistors, the plurality of transistors configured to drive the ultrasound transducer in response to dynamic currents generated at gates corresponding to one or more of the plurality of transistors,
wherein the pulse circuit is a three-level pulse circuit, including a positive high voltage circuit and a negative high voltage circuit, both the positive high voltage circuit and the negative high voltage circuit configured to drive the ultrasound transducer.
