Java实现解析dcm医学影像文件并提取文件信息的方法示例

本文实例讲述了java实现解析dcm医学影像文件并提取文件信息的方法。分享给大家供大家参考，具体如下：

一、安装

首先去github 下载源码，然后执行mvn install进行本地安装，maven中央仓库，竟然没有该jar。。安装成功之后如下:

然后在pom.xml文件中引入该jar包:

				?

									<dependency>

									  <groupid>org.dcm4che</groupid>

									  <artifactid>dcm4che-core</artifactid>

									  <version>3.3.2</version>

									</dependency>

二、测试类
