While consulting for medical projects over the years and working on some, I collected hundreds of domain-specific libraries and frameworks built to help developers make medical applications. However, many of the libraries were not supported or popular enough to survive as they were abandoned by their creators over the years.

Here in Medevel, we are always keeping an eye on medical and health-care development libraries and frameworks for building clinical, medical imaging and digital pathology applications. So, It's the time for this list which contains the most used and production-ready frameworks and libraries.

Although I already wrote about DICOM libraries and frameworks here in this blog to serve as guides for developers and programmers, my list is still growing to include user-interfaces toolkits, medical records frameworks. So I decided to write this article.

We (Medevel.com) made several tests with most of these open-source libraries listed here and prepared notes for some of our customers to help them choose the best that fits their projects' requirements.

Why choose an open-source Framework/ Library for Building Clinical and Medical Apps?

  • The freedom of license, legal issues
  • The community
  • Own your data
  • More involvement of your team
  • Custom workflow/ case design on top of the framework

Things to consider

The decision to use open-source case-specific framework or library should always come with these considerations:

  1. Is the project frequently updated?
  2. Is it supported by its creators?
  3. How big and active its community?
  4. Does it have enough demos and tutorials?
  5. Does it use popular supported or unpopular technologies?
  6. Is the code-based outdated?
  7. Does it have poor or good support?
  8. How is the project's documentation?

Please note the order of this list does not reflect the strength of the project.

Open-source Medical and Health-care Frameworks and Libraries

1- Opal: Medical records specific framework

Opal is my top pick here because I consider it the best project to address the creation of electronic medical records "EMR/ EHR".  It's built-on top of Django which is an old but powerful python framework for creating rich database applications.

I used Django to create two EMR solutions for clients, and I consider Django is the best stable solution to create medical record applications, in terms of application structure, clean-code , support, and finding/ hiring Django-developers to keep up the project updated.

Opal provides a set of command-line tools, modules, batteries to ease the production of EMR solutions. It has rich documentation and a powerful community of developers in its back.

The only downside for Opal is that it's based on the old version of Django. It uses Angular; a JavaScript client framework, and the Bootstrap CSS framework. However, This is the only framework/ library on this list that provides a complete set and support for building electronic medical records applications.

2- OHIF Viewer

OHIF Viewer is a product of OHIF "Open Health Imaging Foundation"; It's an advanced feature-rich web-based DICOM viewer. It's a good option for developers who want to build web-based DICOM applications. The project is well-supported, well documented, and built with modern technologies (Node.JS and React) that make it easy to find developers to customize it.

OHIF Viewer is almost the only project on this list that can create both DICOM viewer and Whole-Slide Image (Digital Pathology/ Virtual Slide) Viewer.
OHIF viewer is our top pick as an open-source web-based DICOM viewer.

Recommended for: Building Web-based DICOM applications.

3- Cornerstone: DICOM Viewer toolkit

Building a web-based DICOM from scratch is not easy, That requires hundreds of hours for developing, testing, fixing bugs, and managing usability issues. So here comes this library. Cornerstone is a library to build web-based browser-ready DICOM viewers. It has a long-list of function-ready tools to do almost everything with DICOM files.

It's also battled-tested with real-world applications, to explain more check OHIF Viewer which uses it.
