The objective of this study was to evaluate the image quality and dynamic range of two digital radiographic storage phosphor systems: Digora (Soredex, Finland) and DenOptix (Gendex, USA). Four objects were analyzed and eight exposure times employed, totaling 64 images that were analyzed by 5 examiners using a scale from 1 to 4 to classify the images. The scores were submitted to analysis of variance and the results showed statistical differences among the averages attributed to the systems, to the exposition times and to the objects (p 0.01 Pound). Digora presented a larger dynamic range and, in general, a better image quality. Although these 2 systems present the same photon detector, they present different results in relation to the evaluated items.
Digora（芬兰Soredex公司）和DenOptix（美国Gendex公司）。分析了四个物体，并采用了八个曝光时间，共64张图像，由5名检查人员使用1至4的评分标准对图像进行分类。对评分进行方差分析，结果显示，归因于系统、曝光时间和物体的平均值之间存在统计学差异（p<0.01）。Digora具有更大的动态范围，总体而言图像质量更好。尽管这两种系统使用相同的光子探测器，但在评估项目方面呈现出不同的结果。
