摘　　要：背景:口腔锥形束CT具有图像精度高、扫描时间短、辐射剂量小、空间分辨率高等优势,它应用于口腔临床至今约10余年,但发展迅速,现已广泛应用于口腔医学临床。目的:介绍锥形束CT的数据处理特点、工作站配置、数据存储传输,及其在口腔临床医疗科研中的应用价值。方法:查阅有关CT影像存储与传输的文献资料,结合口腔锥形束CT数据的特点,举例说明锥形束CT工作站的设计与配置、影像存储架构的设计、诊断工作站软件和硬件的配置。采用锥形束CT对口腔临床患者进行CT扫描,分析锥形束CT在口腔临床的应用效果。结果与结论:口腔锥形束CT影像的数据量较大,宜采用存储区域网存储架构进行影像资料的存储:诊断工作站电脑的配置应高于CT设备厂家的推荐参数,同时应配备激光干式打印机等设备以便图像输出。口腔锥形束CT可以提供口腔颌面部硬组织结构的三维影像及任意层面的断层影像,有利于口腔颌面部疾病的影像诊断。提示口腔锥形束CT影像对于口腔临床医疗工作具有重要价值。BACKGROUND：Cone beam CT（CBCT） has many advantages such as high quality image,short scanning time,low dose radiation and high space resolution.It has been used in clinical dentistry for over ten years.OBJECTIVE：To introduce the characteristics of CT data analyses,configuration of computer working station,image storage and transfer,and the clinic value of CBCT used in dental clinic and research.METHODS：The documents of CT data storage and transfer were reviewed.The characteristics of CBCT data,the configuration of image transfer apparatus and the diagnosis work station and the printer instrument were discussed.CBCT application in the field of dentistry was also introduced.RESULTS AND CONCLUSION：The CBCT data is large.It is necessary to adopt Storage Area Network to store and transfer CBCT image.The configuration of diagnosis work station should be higher than that of recommendation of factory.In addition,laser film printer is essential.CBCT can provide three dimensional and cross sectional image of oral and maxillofacial area.CBCT has more advantages to perform diagnosis of oral and maxillofacial area.CBCT is very important for clinic dentistry.
