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