Abstract
A system for temporal transmit apodization of an ultrasound transducer array. The system includes a waveform generator and an ultrasound transducer array having a plurality of transducer elements. Each of the transducer elements is driven by a signal generator that generates a periodic waveform. The duty cycle of each signal generator is determined by a predetermined setting of a duty cycle control. The duty cycle of each signal generator is calculated to achieve a desired beam profile of the transducer array, such as acoustic focusing for reducing the level of grating lobes and side lobes. Apodization is achieved by varying the effective amplitude at each array element by varying the duty cycle of the signal provided to each element.
