ABSTRACT:
In a method of recording a radiation image by use of a stimulable phosphor in which the stimulable phosphor is first exposed to an imagewise radiation to store the energy of the radiation and then is exposed to stimulating rays to emit light in accordance with the energy stored therein, the instantaneous emission of light emitted upon exposure of the stimulable phosphor to the radiation is detected to measure the level of the energy of the radiation stored in the phosphor. The instantaneous emission is detected by a photosensor which is located behind the phosphor. The output of the photosensor is utilized to control the density and/or contrast of the final image recorded on a photographic film which is recorded by use of the light emitted by the phosphor upon stimulated.
