1. A system for localizing a three-dimensional field of view, the system comprising:
a beamforming ultrasound imaging probe is configured to transmit and receive ultrasound signals within the three-dimensional field of view comprising a plurality of predetermined sub-volumes, each sub-volume of the plurality of predetermined sub-volumes defined by a two-dimensional array of beams;
a controller in communication with the beamforming ultrasound imaging probe, the controller comprising a first processor and is configured to cause the beamforming ultrasound imaging probe to scan the plurality of predetermined sub-volumes sequentially by transmitting and receiving ultrasound signals corresponding to each beam;
a tracking system in communication with the beamforming ultrasound imaging probe and the controller, the tracking system comprising a second processor configured to:
determine a position of a position indicator disposed within the three-dimensional field of view, and
determine a sub-volume of the plurality of predetermined sub-volumes in which the position indicator is located based on the scan of the plurality of predetermined sub-volumes; and
the first processor of the controller further configured to:
cause the beamforming ultrasound imaging probe to scan the plurality of predetermined sub-volumes by transmitting and receiving ultrasound signals corresponding to each beam of the two-dimensional array of beams, and
cause the beamforming ultrasound imaging probe to provide a localized field of view including the position of the position indicator by constraining the transmitting and receiving of ultrasound signals by the beamforming ultrasound imaging probe to a portion of the determined sub-volume in which the position indicator is located.
