Claim Text:
1. A computer-implemented method utilizing a processor executing computer-executable instructions for tracking an anatomical feature of interest using an imaging device, the method comprising: receiving a series of three dimensional images of a region of interest acquired by the imaging device at a first image acquisition rate, wherein the region of interest includes the anatomical feature of interest; determining, by the processor, a location of the anatomical feature of interest in the region of interest; receiving temporally-displaced targeted subsets of ultrasound images acquired by the imaging device at a second image acquisition rate greater than the first image acquisition rate for the determined location; comparing, by the processor, each targeted subset with at least one of the three dimensional images; determining, by the processor, a displacement of the anatomical feature based on each comparison; and using the determined displacement to determine whether to modify a radiation therapy treatment plan.
