Ultrasound motion tracking to evaluate renal functionality

A system for performing ultrasound tracking, the system comprising:

• an ultrasound detector;
• a processor configured to execute machine readable instructions;
• and
• a non-transitory computer-readable memory having machine readable instructions stored thereon, that when executed by the processor, cause the system to:
• obtain, by an ultrasound sensor, a plurality of ultrasound images of a region of tissue of a patient, the plurality of images including a first ultrasound image and a second ultrasound image, the second ultrasound image obtained at a different time than the first ultrasound image;
• identify a reference region at a first position in the first ultrasound image, the reference region including a reference element;
• identify one or more regions of interest in the first ultrasound image, the one or more regions of interest including one or more target elements, the one or more regions of interest each having respective first positions relative to the reference region in the first ultrasound image;
• determine a second position of the reference region in the second image of the plurality of images;
• determine a change in position of the reference region from the first position and the second position of the reference region;
• determine a second position of each of the regions of interest in the second ultrasound image from the change in position of the reference region;
• determine respective ultrasound signal intensity values for each of the one or more regions of interest in the first and second ultrasound images;
• generate a time dependent ultrasound signal intensity curve from the respective ultrasound signal intensity values;
• and,
• determine renal functionality and evaluate pyeloplasty from the time dependent ultrasound signal intensity curve.
