摘要： In a radiation image recording system in which a stimulable phosphor sheet is exposed to an imagewise radiation to record a latent image of a radiation image in the form of stored energy of radiation, the stimulable phosphor sheet is then exposed to stimulating rays to emit light according to the stored energy of radiation, and the emitted light is detected to obtain an image signal, light spontaneously emitted from the stimulable phosphor sheet upon exposure to the imagewise radiation is detected. Then, image processing data such as the maximum value, the minimum value and/or the average value of the stored energy level over the entire area of the image are calculated based on the amount of the light, and is recorded on the stimulable phosphor sheet or the cassette thereof. The image processing data are used for processing the image signal when recording a final image on a recording material.

摘要： In a radiation image recording system in which a radiation image is once recorded in a stimulable phosphor and then read out and reproduced on a recording material, the gradation of the radiation image is processed to enhance the diagnostic efficiency and accuracy of the image. The radiation image is read out by scanning the stimulable phosphor by a stimulating ray to cause the phosphor to emit light of the amount corresponding to the radiation energy stored in the phosphor. The emitted light is detected and converted to an electric signal. The level of the electric signal is converted in such a way that the maximum level of the signal corresponding to the maximum density of the radiation image is converted to a level resulting in the optical density of 1.5 to 2.8 in the reproduced image on a recording material and the minimum level corresponding to the minimum density is converted to a level resulting in the optical density of fog density of the recording material to fog density plus 0.3, and a density curve in a coordinate having an ordinate representing the optical density and an abscissa representing the level of the electric signal has a positive gradient from the minimum level to the maximum level.

摘要： In a radiation image recording system using a stimulable phosphor in which a radiation image is once recorded and then read out by use of stimulating rays impinging thereupon, the gradation of the image is processed by setting the read out level of the read out system and by setting the gain of the read out system. Among the image signal read out from the stimulable phosphor, the maximum Smax, the minimum Smin and the average S are determined. When logSmax-logSmin is less than a predetermined value, Smin is made a standard input signal. When it is more than the predetermined value, S or (logSmax+logSmin)/2 is made a standard input signal. The standard input signal is read out as a predetermined level of a standard output signal. Further, the gain of amplification in the image read out system is controlled to be .DELTA.s/(logSmax-logSmin) in the former case, and is fixed in the latter case, where .DELTA.s is a reproduced signal region.
