Claim 19:
20. A method for controlling operation of a hybrid transmitter of an ultrasound imaging system comprising an ultrasound transducer to transmit ultrasound waves toward a subject area of a patient and a hybrid transmitter comprising: a controller; a waveform memory coupled to the controller to store a representation of an output waveform sequence supplied by the controller; a transmit/receive switch having an output coupled to drive the ultrasound transducer; an N-bit digital-to-analog converter having an input coupled to receive N bits of the waveform memory; a linear transmitter having an input coupled to the N-bit digital-to-analog converter and an output coupled to the transmit/receive switch, the linear transmitter to generate linear transmitter output; a switching transmitter having an input coupled to receive M bits of the waveform memory and an output coupled to the transmit/receive switch, the switching transmitter to generate switching transmitter output, wherein the switching transmitter is a trilevel transmitter, the method comprising:
identifying a hybrid transmitter operation model for the hybrid transmitter of the ultrasound imaging system; and
controlling operation of the linear transmitter and the switching transmitter by the controller according to the hybrid transmitter operation model to generate desired hybrid transmitter output for driving the ultrasound transducer.
