A method for ultrasound imaging utilizes microbeamforming within a transducer probe in electrical communication with a base ultrasound system. The transducer elements are arranged in sub-arrays or subsets, and the transducer includes a cross-point/summation switch in communication with each sub-array, and the base ultrasound system. In the microbeamforming operation, the signals received at the receiving elements comprising a sub-array are summed to generate a composite sub-array signal for same sub-array, and a set of composite sub-array signals corresponding to a particular receive beamforming pattern is defined using a signal controlling the output of the cross-point switch.
