ABSTRACT:
An imaging probe having multi-level transmitter cells. The imaging probe includes a plurality of acoustical sub-elements for transmitting and receiving acoustic energy for imaging. Each of the multi-level transmitter cells is arranged along a respective transmitter cell path between a switching matrix and one of the acoustical sub-elements. The multi-level transmitter cells in the probe are capable of producing signals having multiple voltage levels.
