ClearCanvas Workstation
ClearCanvas Workstation, Community Edition is a free and open source integrated RIS Client and DICOM PACS viewer. The Community Edition is fully functional and built on our highly extensible application framework, making it easy to build new tools for testing in clinical environments.
The Workstation can be installed in either standalone mode, as a DICOM image viewer only, or as an integrated RIS client. Using the Workstation as a RIS client requires our RIS Server.
Note that ClearCanvas Workstation, Community Edition is not FDA-cleared and therefore is not intended for diagnostic use. If you enjoy using ClearCanvas Workstation and require a diagnostic viewer, you can check out ClearCanvas Workstation, Clinical Edition, our FDA-cleared DICOM viewer that includes several value-added features such as Hanging Protocols, Media Writing, and DICOM print.

The ImageServer is extremely scalable and can meet any need, from a small clinic to a multi-site hospital network with thousands of studies. It's easy-to-use web-based interface makes administration tasks simple, and our powerful rules engine enables any number of auto routing tasks to be configured.

ClearCanvas SDK and
Application Framework
If you're developing a business solution based on an imaging model, you'll be interested in the ClearCanvas Application Framework and SDK. The Framework is the foundation for all of our current and future applications. Our PACS Viewer, PACS Server and RIS are all built on top of it. It's a flexible, .NET based development platform, where new functionality can be added to existing applications by way of plugins. For example, if you wanted to add your latest and greatest image processing algorithm to the PACS viewer, you can write a plugin to do so. Or if you want to tightly integrate the viewer with your existing RIS so your users have a seamless workflow experience, you can do that too. We are continuously improving the Framework by adding new features and making it as easy as possible to use so that developers and researchers can concentrate on things that are of core importance to them, not mundane stuff like logging, auditing, window management, etc.
Features
The ClearCanvas SDK (Software Development Kit) helps you leverage the Framework by providing you with tools to help you write plugins. It comes with all you need to get started with plugin writing:
- ClearCanvas Application Framework
- Visual Studio 2008 templates and wizards
- Developer's Guide
- Framework API Reference.
Recommended System Requirements
For instructions on downloading the source code (separate from the SDK), see the Developer's Portal. For more information, see the ClearCanvas Developer's Guide.
Why We Believe in Open Source
ClearCanvas has always believed that as a company, we need to do more than build great software and generate revenue. And because we work in the healthcare industry, we believe that our corporate mission is to improve the lives of everyone involved: from patients, to technologists and radiologists, to solution providers, to our own employees. So for us, building software in the healthcare industry has come to mean three things:
Accessibility. We want people to have access to our software regardless of location or budget. If our software can improve the lives of people who need it, then we want our software available to meet that need.
Empowerment. We want to empower people implementing software solutions in the healthcare industry. Instead of feeling locked-in to expensive solutions that don’t meet their needs, we want people to have the ability to freely modify our software in whatever way necessary to improve the service they provide.
Sustainability. We want to provide high-quailty software to the healthcare industry, and enable others to do the same, whether creating new solutions, reselling existing products, or offering consulting and technical support.
For these reasons, ClearCanvas has made the principles of Open Source software an important part of how we do business. This allows us to guarantee that people interested in our software are free to use and modify it however they see fit, encourage sharing changes openly so others can benefit, and to ensure that anyone who sells and supports our software is free to make a living doing so.
How We License Our Software
In order to fully realize the values of accessibility, empowerment, and sustainability through our software, we have adopted a dual-licensing model based on the Open Software License v3.0 (OSL) and the ClearCanvas Proprietary Source Code License (PSCL).
Open source releases of our software are licensed under the OSL, a copyleft license that requires any redistribution of software, with or without changes, to pass along the freedom to further copy and change that software. At the same time, people are free to distribute, use, sell, and offer support for that software however they see fit.
For companies and developers who want to customize our software while also maintaining proprietary control over their changes, we offer the ClearCanvas Proprietary Source Code License.
The Open Software License
The Open Software License v3.0 (OSL) requires that all derivative work must also be licensed under the OSL. This means that anyone who modifies our source code (including rebranding the software), re-compiles it and distributes the resulting binaries, must:
- License the modified source code using the OSL.
- Make the modified source code available to the public. This can be achieved by doing one of the following:
- Including the modified source with the distribution.
- Hosting the modified source code in the author's own repository, or a public repository such as SourceForge.
- Submitting the modified source code to us as a patch.
- In the case of b) or c) above, inform the public where to look for the modified source code, in say, the license file.
Since ClearCanvas software supports plugins, the original source code does not need to be modified to extend the functionality of the software. Plugins may be licensed and distributed however the author sees fit.
The ClearCanvas Proprietary Source Code License (PSCL)
The ClearCanvas Proprietary Source Code License offers flexibility to companies and developers who require proprietary licensing as part of their business model. For more information about our PSCL, contact sales@clearcanvas.ca.
