Veterans Health Information Systems and Technology Architecture is a healthcare information system (HIS). VistA is widely believed to be the largest integrated HIS in the world. It was originally developed and maintained by the U.S. Department of Veterans Affairs (VA), based on the systems software architecture and implementation methodology developed by the U.S. Public Health Service jointly with the National Bureau of Standards. It is designed to provide a high-quality medical care environment for the country's military veterans. VistA has a proven track record of supporting a large variety of clinical settings and medical delivery systems.
Aeskulap is a medical image viewer. It is able to load a series of special images stored in the DICOM format for review. It is able to query and fetch DICOM images from archive nodes (also called PACS) over the network. The goal of this project is to create a full open source replacement for commercially available DICOM viewers. It is based on gtkmm, glademm, and gconfmm and designed to run under Linux. Ports of these packages are available for different platforms. It should be quite easy to port It to any platform were these packages are available.
Kradview is a viewer of images obtained from different sources such as X-ray, NMR, and DICOM-compatible imaging devices. Its aim is to be an easy-to-use DICOM viewer with instant rendering of images, no matter the size and the zoom of the DICOM image. It allows medical professionals to view X-ray images easily.
GNUmed is a comprehensive scalable software solution for electronic medical practices with an emphasis on privacy protection, secure patient centric record sharing, decision support, and ease of use. It is intended to become a sophisticated decision support system that will elevate the quality of medical care that can be delivered.
The Medical Imaging Interaction Toolkit (MITK) is a C++ class library which aims at supporting the development of leading-edge medical imaging software with a high degree of interaction. It includes a QT-based demo application showing level set segmentation, volumetry, and a step-by-step tutorial. It combines VTK, ITK, and the pic-based-libraries of the Div. Medical and Biological Informatics of the DKFZ, and adds those features that are most important for developing interactive medical imaging software covered neither by VTK nor ITK.
ClearHealth is a fully comprehensive practice management system and EMR. It takes DNA from the FreeMED and OpenEMR projects, and is based on the Smarty templating engine. It includes support for medications, SOAP data entry, clinical reporting, e-prescribing, and labs. Feature for feature, it can compete with proprietary systems like Nextgen and GE Centricity. It includes support for the iPhone and iPod touch (native application).
PING is a distributed, Web-based, personally controlled electronic medical record system that is ubiquitously accessible to the nomadic user and built to public standards. It is essentially an inversion of the current approach to medical records, in that the record resides with the patients, who grant permissions to the institutions, clinicians, researchers, and other users of the medical information. It includes various tools and APIs that address the technical aspects of personally controlled health records. Some of these include a Servlet-based, pluggable, Web services server, a Java Swing-based application for viewing and manipulating records, and an application for generating bar codes used to fax documents into a record.
