Claim 10:
11. An imaging plate scanner configured to perform operations, comprising:
carrying out an exposure of an imaging plate;
carrying out a scan of the imaging plate to determine an image;
removing markings from the image to generate a preprocessed image;
determining a local signal-to-noise ratio for each pixel of a plurality of pixels of the preprocessed image using an associated averaging array comprising a local subset of the plurality of pixels;
marking a first subset of the plurality of pixels for which their local signal-to-noise ratios are below a threshold value;
carrying out an edge recognition on the preprocessed image;
marking a second subset of the plurality of pixels corresponding to recognized edges; and
calculating a quality value of the imaging plate using a ratio of the first and second sets of marked pixels to the plurality of pixels of the preprocessed image.
