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.
Indivo is the original personally controlled health record (PCHR) system. A PCHR enables an individual to own and manage a complete, secure, digital copy of her health and wellness information. Indivo integrates health information across sites of care and over time. Indivo is free and open-source, uses open, unencumbered standards, and is actively deployed in diverse settings, in particular our own Children's Hospital Boston and the Dossia Consortium.
Mirth is an open source cross-platform HL7 interface engine that enables bi-directional sending of HL7 messages between systems and applications over multiple transports. It is divided in three subprojects:
- Mirth Connect: Specifically designed for HL7 message integration, Mirth Connect provides the necessary tools for developing, testing, deploying, and monitoring interfaces.
ATNA is an IHE security profile representing Audit Trail and Node Authentication. OpenATNA is an implementation of an Audit Record Repository supporting RFC 3881 audit messages over BSD Syslog as well as RFC 5424-5426 (UDP and TLS).
- Optimizes the database so that entities such as active participants, audit sources, participant objects and codes are not duplicated for every message received.
- Performs validation of messages as they arrive.
- Optionally logs errors as well as audit messages.
- Supports TLS and UDP.
MRIdb is an end-to-end data management system for MRI, combining the DCM4CHEE DICOM server with a bespoke front-end packaged into an easily deployable virtual machine. It interfaces directly with MRI scanners and handles image storage, retrieval and export. It provides role-based access control, patient-study assignment, and extensive auditing. MRIdb is the result of an ongoing collaboration between the BSS and the Imaging Sciences Department of Imperial College.

EtherCIS (Ethereal Clinical Information System) is an Open Source platform compatible with the openEHR standard. It is design to allow simple interactions with clients using RESTful API and persist clinical data in a separate DB engine. Clinical data are exchanged using different formats:
FLAT JSON: which is a flatten representation of access path along with the corresponding field value
Canonical XML: representing an openEHR composition in standard XML
For more details on data representation in openEHR see this page
