Radical Imaging Builds Custom Viewers

Dreaming of the perfect medical imaging viewer? We can help you build it!

OHIF and Cornerstone are great tools for building custom viewer applications and workflows because they already handle most of lower-level functions (such as DICOM parsing, image loading, cache management, layout management, rendering, etc.), are designed to be extensible and published as MIT licensed open-source; but making the most of these technologies takes quite a bit of knowledge and experience.

In addition to co-creating OHIF with our colleagues at Massachusetts General Hospital Department of Radiology, the experts at Radical have helped dozens of clients design and build their custom viewer applications.

Using our deep knowledge of OHIF and adjacent technologies, we can assist your team in solving your most complex medical imaging problems, and integrate the solution into your workflow.

We'd love to hear about your dream viewer: schedule a discovery call with us!

"I engaged Radical Imaging to integrate and customize the OHIF viewer into the Flywheel research platform. My goal was to accelerate product development without derailing the core roadmap. Mission accomplished! I very much enjoyed working with Rob and the Radical Imaging team. They have deep understanding of the medical imaging space and repeatedly demonstrated professionalism, flexibility, and subject matter expertise."

How Radical Imaging Approaches Custom Viewer Projects

We start by learning about your medical imaging needs during a discovery call. Based on what we learn, we determine how best to work together to build your custom viewer. 

Reference Implementations

The Open Health Imaging Foundation (OHIF) was launched in 2015 through a development partnership between Massachusetts General Hospital (MGH) Department of Radiology and Radical Imaging to create an open source web-based medical imaging platform for the global community. The partnership combines the project management, user experience design, and product testing experience of the MGH group with the software development and system design expertise of Radical Imaging. Funding for OHIF has been primarily through research grants to MGH, direct funding from MGH Department of Radiology and its Precision Imaging Metrics clinical trials informatics project, Radical Imaging through in-kind support, and academic-industry technical collaborations among MGH, Radical, and companies using the OHIF Framework. Here are some example projects from the collaboration between Radical and MGH using OHIF.

OHIF Viewer

OHIF Viewer

The OHIF Viewer is a zero-footprint all-purpose radiology viewer based on Cornerstone that meets the minimum requirements for the IHE Basic Image Review profile. The code is organized into packages that can be re-used to build other purpose-specific viewers to accommodate a variety of custom workflows. OHIF has formed the basis for many viewer projects world-wide.

Crowds Cure Cancer

Crowds Cure Cancer is a web-based image viewer that allows researchers from around the globe to access the database and contribute using a fun, spirited application. The deployed viewer works across all platforms including desktops, laptop, tablets and mobile devices.
