An ultrasound imaging system, comprising: a continuous ultrasound transducer array, the ultrasound transducer array having a concave curvature about at least one axis; a first transmit aperture (T 1) in the ultrasound transducer array comprising a transmitter group of at least one transducer element configured to insonify a scatterer with unfocused ultrasound pings; a second transmit aperture (T 2) in the ultrasound transducer array configured to insonify the scatterer with unfocused ultrasound pings; a first receive aperture (R 2) in the ultrasound transducer array comprising a first receiver group of transducer elements configured to receive volumetric data from the unfocused ultrasound pings, the first receive aperture being located apart from the first transmit aperture; a second receive aperture (R 3) in the ultrasound transducer array comprising a second receiver group of transducer elements configured to receive volumetric data from the unfocused ultrasound pings, the second receive aperture being located apart from the first transmit aperture and the first receive aperture; and a control system in electronic communication with the ultrasound transducer array, the control system configured to: adjust a receive aperture size of the first receive aperture and of the second receive aperture to determine an optimum receive aperture size that retains the best signal to noise ratio while still in phase, coherently average the volumetric data from each of the transducer elements of the first receiver group to create a first volume, coherently average the volumetric data from each of the transducer elements of the second receiver group to create a second volume, and incoherently average the first and second volumes to create a 3D volume, and change an aperture view angle of the system by switching from transmitting ultrasound energy with the first transmit aperture to transmitting ultrasound energy with the second transmit aperture, and switching from receiving echoes with the first receive aperture to receiving echoes with the second receive aperture, wherein a transmit/receive angle between the first transmit aperture and the first receive aperture is approximately the same as the transmit/receive angle between the second transmit aperture and the second receive aperture. a continuous ultrasound transducer array, the ultrasound transducer array having a concave curvature about at least one axis;
