The different processing methods which could increase the contrast (unsharp mask, histogram equalization, and deconvolution) and reduce noise (median filter) were analysed. An application which allows the importation of BeamView files (ACR-NEMA 2.0 format) and the application of the above mentioned methods were developed. The main objective was to obtain the most accurate comparison of Beamview images with Digitally Received Radiograms. The preliminary results of image processing methods are presented.
