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*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
