    Abstract: An ultrasonic diagnostic imaging system includes a CMUT transducer probe with an array of CMUT cells that can be configured to operate in different frequency ranges and with different acoustic element pitches for different clinical applications. The frequency response of the CMUT cells can be tailored for different clinical applications by increasing the DC bias voltage for higher frequency clinical applications, or decreasing the DC bias voltage for lower frequency applications. Individual acoustic elements including groups of CMUT cells can be configured to have a desired pitch that is optimal for the frequency being used for the imaging application.

    Abstract: An ultrasound generator comprising a signal generator and a transducer, and a method of generating ultrasound. The signal generator is arranged to receive, generate or calculate when instructed a modulating signal with a magnitude that varies within a first range, the signal generator is further arranged to generate a pulsed drive signal having a predefined first relationship to the modulating signal, the pulsed drive signal having at least a zero output level, a positive output level and a negative output level, wherein the position and width of pulses are defined by at least first and second switching angles per half cycle of the modulating signal. The transducer is arranged to generate ultrasound in response to the pulsed drive signal. The first relationship is selected such that within at least part of the range of magnitude of the modulating signal the first and second switching angles are adjusted simultaneously to provide for an increase or decrease in the magnitude of the fundamental frequency of the pulsed drive signal corresponding to an increase or decrease in the magnitude of the modulating signal. The first relationship is also selected such that a selected harmonic component of the generated pulsed drive signal is maintained below a first threshold.
