Image gradation processing method and apparatus for radiation image recording system

Patent ·
OSTI ID:5705922
A method and apparatus for processing a radiation image in a radiation image recording system in which a stimulable phosphor is stimulated with a scanning stimulating ray and the light emitted from the stimulable phosphor upon stimulation by the stimulating ray is detected by a photodetector which gives an output to be processed and used for recording a visible image on a recording medium. The radiation image of the frontal chest is gradation processed. The gradation processing is characterized in that the density at the boundary of the heart and the lungs of the image on the recording medium is lowered to lower the contrast of the heat and raise the contrast of the lungs.
