Hello OHIF Community!

Spring is here and with it we have some new changes to OHIF! 2023 is shaping up to be an exciting year for the OHIF product team and community with some big updates to come. For now let’s take a look at the latest release which covers new features in the OHIF Viewer, grant updates, collaborations, and some news you may have missed. Let's dive in!

New Viewport State Preservation

We have enhanced state synchronization in OHIF Viewer, ensuring a seamless user experience when switching between Multiplanar Reformatting (MPR) and other views. The viewer now remembers attributes like window leveling, image index, zoom, and pan, maintaining these settings even as you navigate through hanging protocol stages. This upgrade provides a more consistent experience and prevents the loss of viewport modifications.

Enhanced Hanging Protocol Matching

We've improved hanging protocols with faster display set matching for a more user-friendly experience. Check the demo below and use period (.) and comma (,) keys to navigate between stages.

Customizable Context Menu

Context menu options have been expanded, allowing for greater customization and even the addition of sub-menus to any desired depth. This makes it easier for you to access the tools you need, exactly how you want them.

UI/UX Improvements

Improved Viewport Header Design

We have revamped the viewport header to better match the overall viewer layout and design. The new design is visually appealing and space-efficient, ensuring a more streamlined user experience without wasting any screen real estate.

Double Click to Maximize Viewport

We have added the ability to double-click to maximize viewport in all our modes. The enhancement also remembers the viewport state information in order to easily return to the original layout. This has been a highly requested quality of life improvement that we are happy to add to the end user experience.

Coming Soon: Volume Rendering

We are excited to offer a sneak peek at our in-development 3D volume rendering viewport, powered by Cornerstone3D. Give our demo a try, which showcases a CT image with an interactive 3D viewport. We'll be introducing preset customization and other rendering improvements in future. A special thanks to our friends at Kitware for providing vtk.js, the library behind our volume rendering. Check out the demo using the link below!

Grant Updates

Chan Zuckerberg Initiative Diversity & Inclusion

Our Hack.Diversity collaboration has been successful, with two impressive cohorts from New York and Boston developing applications based on the MERN stack (MongoDB, Express, React, and Node.js).

Here are two screenshots of the apps developed by our talented students! Although we couldn't showcase all of the amazing apps our students created, we're incredibly proud of their hard work and dedication. Many of these talented students are seeking internships to further develop their skills. If your organization is interested in offering internships and benefiting from their expertise, we encourage you to visit Hack.Diversity's page for more information.

On the right is ProjectX app developed by "techdive6" group (members: Titamah Simpson, Luz Agudelo, Donovan Francis, Liban Osman, Nick Johnson, John Fleurimond), and on the left is DoctorHelp created by "the Ops" (members: Tamara Bueno, Ryan Santiago, Aaron Pagoada, Xica Felix, Elijah Agyemang).

We are still actively seeking collaborators for our community mentorship program! This is a unique opportunity for global community members to work 1:1 with our core developers on their OHIF related projects. See more about the grant here.

Preclinical Imaging XNAT-enabled Informatics (PIXI) Collaboration

We have successfully finished the 4D support development for Cornerstone3D and will soon start the OHIF development phase. Following thorough memory profiling, we are excited to present demos featuring 4D PET of a mouse hotel with four animals showing tracer uptake over time. Check out our developer demo below!

Notable Contributions

We want to extend our gratitude to the following organizations for their valuable contributions to our open-source projects:

Voxelwise Imaging Technologies funded the efforts for the hanging protocol improvements and DICOM SR improvements.
Viz.ai added support for a new volume rotate tool and a fix for black area inside volume viewports.
New Lantern added support for the new planar rotate tool for our stack viewports.
Gradient Health contributed touch event support to Cornerstone3D, which in turn facilitates touch events in OHIF.
The Pliny team contributed TypeScript typings to the Cornerstone Image Loader.
