摘　　要：目的:研究数字化X射线摄影系统图像获取工作站显示器配置不同对图像质量的影响及对被检者照射剂量的影响。材料与方法:应用对比度细节体模CDRAD2.0影像,以图像质量因子IQF作为图像质量评价标准,计算不同照射剂量下两种图像显示条件下图像质量及照射剂量的差别。结果:所研究的普通显示器与高分辨率、高亮度显示器在不同照射剂量条件下显示的图像质量因子显著不同(p<0.000)。结论:应用高亮度、高分辨率显示器作为图像获取工作站显示器可显著降低体模照射剂量。Purpose To research the image quality and irradiation dose with different monitor configures of image acquisition workstation in digital radiography. Materials and method The IQF(image quality figure) of a detail-contrast phantom CDRAD 2.0 under different irradiation dose were compared. Result The image quality of detail-contrast phantom displayed on a high resolution and brightness monitor was significantly different from that on common monitor(p<0.000). Conclusion The irradiation dose can be reduced significantly using high resolution and brightness monitor as image acquisition workstation monitor.
