Abstract
A film digitizer is used when X-ray images are entered in the PACS. Dust adhering to the film causes white vertical lines on the readout image displayed on the screen. Once generated, the lines will appear on all subsequent readout film images. These white lines must be removed because they adversely affect CRT diagnosis. This paper shows why vertical lines are generated and describes how these lines are suppressed and effects on aliasing caused when a film radiographed using grid is read by the digitizer.
