Abstract
A method of forming a composite digital image comprising: providing 1-N digital images formed from 1-N contiguous segments of a larger radiographic image recorded in 1-N overlapping storage phosphor screens wherein N is equal to or greater than 2 and wherein the image content in the overlapped region of contiguous images is the same, and the end edge of a screen nearest an x-ray source is present in both contiguous images; selecting a pair of contiguous digital images, wherein one image is closer to said x-ray source than said other image; correcting for any geometric distortion if applicable in said pair of digital images based on the distance between x-ray source and said storage phosphor screen; determining any rotational displacement and any vertical displacement between said pair of digital images by matching said end edge of said one image present in said pair of images correcting for image orientation if applicable based on any said rotational displacement; determining any horizontal displacement between said pair of digital images by correlating the image content in said overlapping regions of said pair of digital images; stitching said pair of digital images together to fo…
