Abstract

　　Since CR systems were introduced in 1983, digitalization of radiography has accelerated. In the case of infants and newborns, X-ray examination is practiced for many reasons, and the management of X-ray exposure is becoming very important. In a general CR system, X-ray images are stored and read from just one side of the imaging plate. On the other hand, in CR with dual-side reading technology, the X-ray image is stored and read from both sides of the imaging plate. Therefore the Signal to Noise Ratio（S/N）is improved, and a study has been carried out to analyze the possibility of decreasing the necessary X-ray exposure. In a study to compare the Contrast Noise Ratio（CNR）, the dual-side CR proved to realize 30％ higher CNR than the single-side CR.
　　The application and possibility for pediatric examination by X-ray equipment with Flat panel detector….? Something missing here.
