ABSTRACT:
An ultrasound mixed signal multiplexer/pre-amplifier application specific integrated circuit (ASIC) for supplying voltages to a group of elements of an ultrasound array, receiving voltages from the same or another group of elements of the array, and amplifying the received voltages for transmission to external circuitry. The transmit groups and receive groups are shifted to provide accurate visual images with a minimal number of transmit and receive cycles.
