Abstract

In this paper, the information capacity, the Integrate performance measure of digital radiography system has been quantitatively analyzed. The effect of various factors affecting the information capacity of the digital radiography system in multi-stage detection processes has been considered and analyzed In detail. The results show that the more Information capacity can be obtained with the smaller detector cell area, despite of the decreasing signal to noise ratio due to the reduced number of X-ray photons per detector cell. And also has been Indicated that the Increase of the information capacity may be severely lost by the addition of electric noise in final read-out stage.
