Abstract
A method and system for controlling bias voltage for use with an electrostatic transducer are provided. The bias voltage is dynamically varied or set as a function of imaging mode, depth gain compensation, elevational apodization, azimuthal apodization, timing with respect to the transmit waveform, center frequency of transmit and receive waves and desired modulation. Opposite polarity on sub-elements is also provided for removing signals from electromagnetic interference and crosstalk between elements.
