Abstract:
A method of optimizing an X-ray image representing an article transilluminated by X-rays, comprising the following steps:(a) detecting the X-rays leaving the article after transillumination thereof by the X-rays; (b) processing, in a computer, the detected X-rays as image dots to obtain an image; (c) applying the image dots to an image memory; (d) scanning the image dots according to gray scale values thereof; (e) comparing the scanned gray scale values with a desired threshold gray scale value; (f) upon finding, in performing step (e), an image dot which is other than said desired threshold gray scale value, counting subsequent image dots-to obtain an image zone A; (g) determining the gray scale values of the image dots of said image zone A; and (h) expanding the gray scale values of the image dots of said image zone A to higher image dot values for effecting a local brightening of the X-ray image in said image zone A by the higher image dot values.
