ABSTRACT:
The present invention is directed generally to correcting geometric distortion in a digitally captured image. The method involves receiving an uncorrected digital image of a phantom having a plurality of fiduciary marks; locating an uncorrected digital position for each of the fiduciary marks; mapping the uncorrected digital position to a corrected digital position for each fiduciary mark; and interpolating or extrapolating the fiduciary mark map to all pixels in the uncorrected digital image, thereby creating a correction map for uncorrected digital images.
