1. A method for generating a time series of images with an ultrasound system, the method comprising:
(a) acquiring ultrasound data from a region-of-interest using an ultrasound system, wherein the ultrasound data are acquired using a series of angled wave emissions over a duration of time such that the ultrasound data comprise angular view data for each of a plurality of temporal sample points;
(b) generating temporally aligned ultrasound data by interpolating the ultrasound data along a temporal domain, thereby generating additional angular view data at each temporal sample point; and
(c) generating a time series of images from the temporally aligned ultrasound data by compounding the angular view data at each temporal sample point, thereby generating an image at each time point corresponding to each temporal sample point.
