Abstract
An ultrasound imaging system according to the present disclosure may include an ultrasound transducer assembly comprising a plurality of apertures that are configured to transmit signals toward and receive signals from a region of interest (ROI) of a subject, a tracking sensor disposed within the subject and configured to move within the ROI, the sensor being responsive to signals transmitted by the apertures, and at least one processor in communication with the ultrasound transducer assembly and the tracking sensor. The at least one processor may be configured to generate a first image of a first portion of the ROI from signals received from at least one activated aperture, identify a position of the tracking sensor using signal data from the tracking sensor that corresponds to at least one signal transmitted by the apertures, and generate a second image of a second portion of the ROI from signals received from at least one other aperture activated based on the identified position, wherein the second portion of the ROI is different from the first portion of the ROI.
