数字化X线摄影测试用具的系列研究

目的:研制数字摄影测试用具,检测X线设备性能。方法:对CR和DR进行测试。结果:铝梯层数显示CR少于DR,用比例尺后准确率提高到90%以下。结论:DR宽容度和低对比度高于CR,比例尺误差小于1mm。

Serial Research on Test Equipment for Digital X-ray Photograph

Objective To study the test equipment for digital X -ray photograph and to check the efficiency of X -ray equipment. Methods CR and DR were checked respectively. Results Slice numbers of aluminum ladder by CR was fewer than that by DR. The accuracy was improved with the value over 90% after the use of measuring scale. Conclusion Width and low contrast for DR is higher than those of CR and measuring scale error is less than 1 millimeter.
