Open Health Tools Model-Driven Health Tools (MDHT) Project is a wide-ranging open source effort to promote interoperability in healthcare infrastructure. It promotes shared artifacts between related healthcare standards and standards development organizations, and works to develop localized specifications. It also delivers a common modeling framework and tools that support seamless integration of design, publication, and runtime artifact creation.

The epSOS project has released interoperability specifications (Common Components Specification) for national Contact Points (NCPs) to interact and support epSOS defined services such as patient summary and prescription. epSOS has also established a testing process for testing compliant implementations of these specifications, and ensure their interoperability.
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.
CONNECT is an open source software solution that supports health information exchange – both locally and at the national level. CONNECT uses Nationwide Health Information Network (NHIN) standards and governance to make sure that health information exchanges are compatible with other exchanges being set up throughout the country.
The IHE Cross Enterprise Document Sharing (XDS.b) integration profile facilitates the registration, distribution and access across health enterprises of patient electronic health records. XDS.b is focused on providing a standards-based specification for managing the sharing of medical summary documents between any healthcare enterprise, ranging from a private physician office to a clinic to an acute care in-patient facility.
This project holds an implementation of the Cross-Enterprise Document Sharing (XDS) profile as defined by IHE (ihe.net). It includes implementations of both the Document Registry and Document Repository actors.
The project is deployed at the XDS Public Registry Test Facility of the National Institute of Standards and Technology (NIST).
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.
To lower the barrier to integration and expedite health care interoperability, Open Health Tools provides client side implementations of several key IHE profiles. These implementations were used successfully by over 35 systems to date at the 2007-2010 Connectathons in North America and Europe.
OpenTele collects clinical health data from citizens at home. Clinicians review data through a web-portal, and take actions upon data, that are beyond the individual’s allowable data boundaries. The system is aimed at increasing the direct involvement of patients and citizens in taking charge of their health, independent of geographical distances between patient and clinicians.
Weasis is a multipurpose web-based viewer with a highly modular architecture. It has been designed to meet several expectations of clinical information systems and their future evolution regarding medical imaging: providing a web-based access to radiological images, as well as offering multimedia capabilities.
Weasis can be easily interfaced to any PACS supporting WADO via a web portal or as an XDS-I consumer in an IHE (Integrating the Healthcare Enterprise) environment (not yet fully implemented). It has been successfully interfaced to dcm4chee and commercial PACS.
