基于XML技术的正常人脑MRI图像数据库

MRI Image Database of Normal Human Brain Based on XML Technology

建立正常人标准脑是全球人类脑计划(HBP)的重要组成部分,建立适合中国人自己的标准脑结构模板更具有重要意义。本研究基于对所采集的3000例正常成人脑结构数据,以及对这些海量数据的有效管理这一关键问题,通过解析医学数字成像和通信标准(DICOM)图像特殊的数据结构,引入了可扩展标记语言(XML),使用拥有自主知识产权的应用软件,设计和完成了NXD(Native XML Database)数据库,以对获取到的大量的脑结构数据进行管理和使用。系统以数据采集、序列分析、案例提取、案例编辑、案例管理为流程,有效减少了数据占有空间和数据冗余,提高了数据处理的速度和效率,使得数据库系统具有可扩充性、结构稳定性、功能独立性和存储效率高等特点。

The research of digitized standard brain of normal human being is an important part of human brain project（HBP）.The establishment of the template of Chinese people is of great significance.Based on the 5 000 cases of MRI data of normal brains,we analyzed the special structure of the digital imaging and communications in medicine（DICOM）.With the introduction of extensible markup language（XML）,we designed and accomplished a Native XML Database to manage and deal with the huge amount of MRI image data.The flow of this database system was data collection,serializing,case extracting,case editing and case managing.This database effectively reduced the data space and data redundancy.Furthermore,it improved data processing speed and efficiency.So the database is an extensible,stable,independent and efficient system.
