Processing method in radiation image recording systems

摘要

The present invention relates to the field of digital image processing. More in particular it relates to a method of processing a radiographic image in a radiographic image recording system in which a stimulable phosphor is scanned with a stimulating ray and the radiographic image information recorded in the stimulable phosphor is read out and converted into an electric signal upon stimulation thereof and the electrical signals are further converted to density values for visualisation of the radiographic image either as a soft copy on the screen of a console or as a hard copy recorded in a photographic recording material on an optical display unit, said method comprising the step of converting the electrical signals of the image points comprised within the diagnostically not relevant image zone within the radiographic image to a density value such that when visualised as either a soft or a hard copy the light transmitted by said image parts from the console screen or the optical display unit is effectively masked off.
