New Features

Segmentation Mode

We are thrilled to roll out our new segmentation mode, packed with a range of interactive tools like brushes, erasers, shapes, and thresholding tools. These tools empower you to create, modify, and perfect your segmentations effortlessly. Once you are satisfied, you can easily download these segmentations or export them directly to your server in DICOM format. Plus, we have optimized our adapters to read segmentation data 3x faster than before, delivering a smoother and more efficient user experience.

We are rolling out volume viewport support for segmentation, as it effectively covers the majority of use cases. Furthermore, we are diligently working on stack viewport segmentation for release in the near future. Stay tuned for more updates!

Cloud Server Configuration UI

We are excited to announce the introduction of a new method for setting up cloud data sources in the OHIF Viewer. Our User Interface (UI) currently supports Google Healthcare API, and its flexible design enables you to seamlessly incorporate additional cloud services. This enhances its versatility and ensures a personalized solution that perfectly aligns with your unique requirements.

OHIF and MONAI Label

We partnered with NVIDIA to migrate the OHIF Viewer v2 MONAI Label plugin to the v3 platform. This exciting collaboration enables you to effortlessly connect your MONAI Label server to OHIF Viewer v3 and leverage a wide range of advanced AI features. Experience the power of whole-body CT segmentation model, MONAI model zoo , train your AI models with active learning, and much more.

NIFTI Volume Loader in Cornerstone 3D

Cornerstone 3D now fully supports NIFTI data. This exciting addition allows you to utilize all the familiar tools for annotation, manipulation, and segmentation on NIFTI datasets, just as you would with DICOM files. Our future plans include expanding NIFTI support to the OHIF Viewer itself. This enhancement will significantly increase the accessibility of our platform to a broader community of researchers who work with diverse imaging formats.

UI Improvements

We now notify users about any issues, such as irregular spacing or missing frames, through warning messages. This implementation greatly enhances the reliability of your imaging work.

Take a look at the revamped design of the side panes, which maximizes space for your content while minimizing the room occupied by the panel header.
