1. A method for the correction of ring artifacts in images of an object obtained by a rotate-rotate computerized tomography (CT) scanner, said method comprising the steps of: (a) reconstructing an original image including ring artifacts, said original image comprising a real image without ring artifacts and a ring artifact image; (b) determining the ring artifact image by the steps of: (i) edge enhancing the original image to obtain an edge enhanced original image; (ii) dividing the edge enhanced original image into specified areas, said specified areas being concentric annuli which are centered about a point in the original image corresponding to the axis of rotation of the scanner; (iii) said step of dividing the image into concentric annuli comprising assigning each pixel of the enhanced original image to a specific one of said concentric annuli, said concentric annuli conforming to the ring artifacts; (iv) determining the average intensity of each concentric ring area of the said enhanced image to provide an average ring artifact pixel intensity value for each annulus; (c) subtracting the average ring artifact pixel intensity value of each annulus from each pixel of the original image that belongs to the same annulus to thereby obtain a ring artifact-free image.
