目的：结合数字化Ｘ线机Ｐｏｌｙｓｔａｒ的使用体会，讨论数字化成像技术的应用价值。材料与方法：８５例患者完成单纯造影３８例，造影及介入治疗５２例，由３位医师评价全部血管造影所见、介入治疗及影像质量。结果：血管造影１５４支，最远解剖段血管分支获满意显示，肝内显示的最小病灶０．８ｃｍ×１．０ｃｍ，影像质量优良片８２例（９６．５％）。结论：数字化成像技术功能多且操作简便，可为临床提供充分信息并减少操作时间和造影剂用量
Objective: To discuss the application value of digital imaging technology in combination with the experience of digital radiography Polystar. Materials and Methods: Thirty-five patients underwent radiography and interventional radiography in 85 patients. All three angiographers evaluated angiography, interventional therapy and imaging quality. Results: There were 154 angiograms and the best vascular segments in the anatomical segment showed satisfactory results. The minimal lesion showed in the liver was 0.8cm × 1.0cm and 82 cases (96.5%) had excellent image quality. Conclusion: The digital imaging technology has many functions and is easy to operate, which can provide sufficient information for the clinic and reduce the operation time and the amount of contrast medium
