摘要: A multi-level pulser for an ultrasound system is provided that receives a reference voltage input signal, a shading signal, and a control signal. The pulser produces an output signal for driving a transducer, with the output signal based on the reference voltage signal, the shading signal, and the control signal. The output signal includes a continuous wave (CW) signal interleaved with a pulse wave (PW) signal. The PW signal may have multiple levels of amplitude.
