ABSTRACT:
A method of and apparatus for the non-destructive inspection and/or evaluation of materials by the computer processing of images produced on/by an image conversion screen/device is disclosed in which the images are produced by placing the object to be inspected and/or evaluated between the screen/device and a source of x-rays from an x-ray machine having the capability of varying its focal spot area size. Two images, one created with a large focal spot size and one created with a small focal spot size are processed and then combined in such a manner so as to accentuate the fine structure detail in the resulting image.
