Claim Text:
1. A pulser logic method for an ultrasound beamformer, comprising the steps of: accessing digital logic memory blocks to establish a transducer element excitation timing sequence; delivering the transducer element excitation timing sequence to a pulse generator, the pulse generator exciting selective pulsers of a multi-element ultrasound array transducer according to the excitation timing sequence; using a delay memory block to store delay values in master clock number of cycles needed for each of the pulsers to begin emitting transmit pulses; and using a pulser trigger memory block having a bit data width corresponding to the number of pulsers in the multi-element ultrasound array transducer, the pulser trigger memory block triggering a corresponding one of the pulsers based on a delay timing associated with the delay memory block; wherein the multi-element ultrasound array transducer forms a wave front focal point having a steerable position determined by the transducer element excitation timing sequence.
