摘　　要：目的：本文就颅脑CT检查中如何提高摆位技巧和摆位的准确率，提高CT图像质量，为诊断提供正确，直观，清晰或基本没有伪影，质量较高的CT片。材料与方法；使用日本岛津SCT－3000TX型全身扫描机，对三年多11189例头颅CT检查病例进行分析与总结。在实践中摸索出一套简便，易学，易掌握的颅脑CT摆位法。用此方法摆位，其结果：不同的头型病人扫描，均能得到准确层面的头颅CT图像，而且伪影少，效果较佳。同时我们将头颅CT片人为分为四个级别，并分析了四个级别图像产生的原因和结果。结果：用随机抽样对改进后（改进法）和改进前（称常规法）各100例，采用Ridit分析，其结果表示：常规法与改进法两种方法，差别有显著性意义。这说明改进法明显优于常规法。结论：此种方法对于全面提高CT室工作质量将是一个促进。Purpose: In this article, We discussed how to improve the quality of the position of skull and its accurate rte,imaging quality, for to offer a distinctive high quality CT film. Materials and methods: Analysed of 11189 cases of skull scan with SHIMADZU 3000 TX CT system in three years, used with advanced technique. The films showed no artifact and with standard slice. We divided these films in four degree. Results: Random sampling each fore 100 cases and analysed to use the Ridit method,there were significant difference in these two methods. Conclusion: We suggest that this method may improve the quality of CT scans.
