树型结构DICOM数据集解析及其在PACS系统中的应用

Parsing and encoding of DICOM Nesting Data Set and its application to PACS

DICOM是在医学数字图像的数据格式和传输方式的工业标准。DICOM数据集是符合DICOM编码规范的二进制流,树型结构的DICOM数据集是具有多叉树结构的复杂数据集。由于其结构的灵活性,被广泛应用于各种DICOM服务类的数据交互以及DICOM文件的编码中。本文详细介绍了DICOM协议中数据集与树型结构数据集的作用以及编码规则,提出了对其进行解析与组织的方法,分析了实现方法,在此基础上探讨了其在实际工作中的应用。

DICOM is a standard for data format and transmission of digital medical image. DICOM Data Set is a binary data stream using DICOM encoding rule. DICOM Nesting Data Set is a kind of complex Data Set with a tree structure, and is widely used in DICOM services and encoding of DICOM files for its special structure. In this article, the functions and encoding rule of Data Set and Nesting Data Set in DICOM format are presented, and the way of parsing and organizing of them is put forward. The realization method and practical application are also discussed.
