摘要
目的:从分辨率角度比较非专业与医用专业显示器显示普通放射数字影像的显示效果。方法:采用SiemensAristos VX直接数字DR对Cardinal Health-Hicksville NY07-535X线测试卡曝光获取测试图像,对各类显示器进行测试。结果:实际大小显示模式下非专业显示器对图像的分辨力都能达到3.7Lp/mm。结论:非专业显示器对图像的分辨力达到了《医用X射线诊断设备影像质量控制检测规范WS/T189-1999》的要求,基本可以用于普通放射影像的诊断。
Objective :.From the view of differentiated rate to compare the effects of nonprofessional with professional medical major display in showing the normal radiation digital images. Methods: Use Siemens Aristos VX directness digital DR to catch test image from exposal of Cardimal Health-Hicksyille. N. Y. 07-535 X-ray test card,and to test different kinds of displays. Results:To use nonprofessional display in full size display mode, the differentiated rate reached 3.7 Lp/mm. Conclusion: The differentiated rate of nonprofessional display, reaching the requirement of Specification of image quality control tests for the medical X-ray diagnostic equipment WS/T189-1999 ,could be used in the diagnosis of normal radiation.
