Abstract
This invention is related to a method for determining the storage quality of an X-ray imaging plate, including the steps of: providing a plurality of digital X-ray images of the imaging plate; performing a cross-correlation operation on the X-ray images for relevant image regions; creating feature images from the correlation values; classifying the functionality of a pixel of a feature image based on the number of pixels in the vicinity of the pixel whose correlation value exceeds a correlation threshold. Further, the invention also relates to an apparatus.
