An ultrasound probe and an ultrasound imaging system include a plurality of transducer elements arranged in an array. The plurality of transducer elements are organized to form a transmit aperture and a receive aperture. The ultrasound probe and ultrasound imaging system include a plurality of summing nodes. The ultrasound probe and ultrasound imaging system include a set of receive switches associated with each of the transducer elements in the receive aperture. Each set of receive switches is configured to selectively connect the associated transducer element to any one of the plurality of summing nodes.
