1. An image acquisition system, comprising; an image recording device configured to determine and record a tracking error associated with a raw image of a moving subject, wherein the raw image is expressed in x-y coordinates; and a computing device configured to deblur the raw image using the tracking error by: determining a convolution kernel based, at least in part on the tracking error, wherein: the convolution kernel is constructed from a residual motion trajectory approximation resulting from the tracking error; and constructing the convolution kernel includes transforming the residual motion trajectory approximation into the x-y coordinates in which the raw image is expressed; and applying the convolution kernel to the raw image.
