Abstract
A technique to correct deficiencies in x-ray images of cylindrical or spherical objects that are a consequence of the geometry of the sample is disclosed, for both normal imaging of stationary objects with film or digital detectors and linescan imaging of moving objects. The methods described involve the use of attenuators specifically shaped to equalize the x-ray absorption across the sample, thus correcting the variation in pixel intensity caused by the varying thickness of the sample.
