Abstract

There are studied for filmness methods due to disadvantage of conventional X-ray system. Have high DQE, high SNR, amorphous selenium was investigated with image plate. In this point, characteristics of all amorphous selenium image plate was investigated to understand the relationship between the amount of the X-ray exposure and the superficial charge potential in this study. Specially, changes in charge at the surface of the amorphous selenium plate with respect to change of X-ray energy(KeV) was investigated. It was found that the surface charge potential at the amorphous selenium inclosed with respect to the increse in X-ray exposure and that the changed surface potential was a semilinearity in 12.5KeV - 22.5KeV range. Therefore, which suggests that these results call be applied to the development of X-ray image plate.
