DICOM Tag editing using dcm4che

dcm4che is a collection of open source applications and utilities for the healthcare enterprise. These applications have been developed in the Java programming language for performance and portability, supporting deployment on JDK 1.4 and up.

At the core of the dcm4che project is a robust implementation of the DICOM standard. The dcm4che-1.x DICOM toolkit is used in many production applications across the world, while the current (2.x) version of the toolkit has been re-architected for high performance and flexibility.

Also contained within the dcm4che project is dcm4chee (the extra ‘e’ stands for ‘enterprise’). dcm4chee is an Image Manager/Image Archive (according to IHE). The application contains the DICOM, HL7 services and interfaces that are required to provide storage, retrieval, and workflow to a healthcare environment. dcm4chee is pre-packaged and deployed within the JBoss application server. By taking advantage of many JBoss features (JMS, EJB, Servlet Engine, etc.), and assuming the role of several IHE actors for the sake of interoperability, the application provides many robust and scalable services:
