Abstract:
A method for motion correction in a series of two-dimensional images of a rigid body, said images respectively having image edges defining a coverage area wherein the rigid body does not lie completely in the coverage area of the images and is cut off at one of said image edges, comprising the steps of:a) selecting first and second chronologically successive images in said series, between which the motion correction is to be implemented, and respectively mirroring said first and second images at said one of said image edges thereby producing two mirror images; b) attaching the first image and the mirror image of the second image and attaching the second image and the mirror image of the first image at said one of said image edges thereby producing two new images that show a rigid body in a good approximation lying completely within said new images; c) determining motion parameters for time-successive images of said rigid body from the two new images according to a motion correction method; and d) correcting said first image and said second image using said motion parameters.
