Abstract:
An ultrasonic beamformer may include an input signal line for each ultrasonic transducer element configured to carry a broadband pulse from the ultrasonic element. The ultrasonic beamformer may include a number of signal shifters that is substantially less than the number of transducer elements. Each signal shifter may be configured to shift a broadband pulse in a way that is different from the way the other signal shifters are configured to shift a broadband pulse. For each of the input signal lines, a multiplexer may be configured to electrically connect the broadband pulse received on the input signal line to a selected one of the signal shifters. A multiplexer controller may be configured to generate the control signal for each of the multiplexers in a fashion that causes the ultrasonic beamformer to substantially compensate for the differences in the distances. A comparable configuration may be used for transmission.
