Example of Java implementation method of parsing dcm medical image files and extracting file information

This article describes the Java method of parsing dcm medical image files and extracting file information. Share it for your reference, as follows:

1. Installation

First, go to Github to download the source code, and then execute mvn install for local installation. The Maven central repository does not have the jar. . After successful installation, the following is as follows:

Then introduce the jar package in the POM.XML file:

 <dependency> <groupId>org.dcm4che</groupId> <artifactId>dcm4che-core</artifactId> <version>3.3.2</version></dependency>
