这篇文章将为大家详细讲解有关Java怎么实现解析dcm医学影像文件并提取文件信息，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。
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
