Radiation image read-out method and apparatus

摘要

In a radiation image read-out system in which a stimulable phosphor sheet carrying a radiation image stored thereon is exposed to a stimulating ray which causes it to emit light in the pattern of the stored image, and the emitted light is photoelectrically read out, preliminary read-out is conducted to investigate the image input information on the phosphor sheet by use of a stimulating ray having stimulation energy lower than stimulation energy in final read-out for obtaining a visible image. The image input information is displayed, e.g., on a CRT to manually set final read-out and image processing conditions or directly sent to a control circuit for automatically setting them. Preliminary and final read-out sections are formed separately, or a single read-out section is used to conduct both read-out steps.
