Hello OHIF community! The latest OHIF update is here! Introducing OHIF Viewer v3.10, bringing new advanced segmentation tools and a major update to our UI component library. Check out the changes below. |
|
|
Local AI Segmentation Tools |
|
OHIF Viewer 3.10 introduces two AI-powered segmentation tools that run entirely in your browser—no server or network needed. |
|
| Labelmap Assist
Quickly extend an existing segmentation to the next / previous slice using the Segment Anything (SAM) model. After propagation, you can fine-tune the result with other tools in the segmentation suite. |
|
|
|
|
|
|
|
|
|
|
|
| Prompt-Based Segmentation
Guide segmentation by placing include or exclude markers. The AI uses these hints to generate precise regions, helping speed up the process while keeping you in control. |
|
|
|
|
|
|
|
|
|
|
|
These tools are designed to make segmentation faster and more efficient. Performance depends on your machine's hardware, so results may vary based on available resources. Let us know how they work for you. |
|
| One Click GPU-Accelerated 3D Segmentation |
|
|
|
|
|
|
|
|
|
|
|
We are enhancing our segmentation suite with a new WebGPU-accelerated 3D GrowCut tool. It runs entirely in the browser, detects segmentable regions in a single interaction, and provides real-time visual feedback for precise selection. To the best of our knowledge, it's the first ever WebGPU implementation of the GrowCut algorithm in the world! |

Brush Preview & Border Hover for Segments |
|
|
|
|
|
|
|
|
|
|
|
| We have added many improved quality of life and utility functions to the segmentation suite. First, the user may now create a segmentation in preview mode. The preview can be accepted, edited, or rejected. This tool can be combined with manual tools such as the brush, or integrated into automated workflows to allow opportunity for human verification of results. |
|
|
|
|
|
|
|
|
|
|
|
We have added the ability to highlight a segment when hovering on the border, making it easier to interact with data containing large amounts of segments or many small regions of interest. |
|
|
Undo & Redo Any Viewport Action |
|
A highly requested feature is now arriving! Now any action in the viewport can be undone or redone with a simple button click or hotkey press. This includes segmentation tools, measurements, and other user inputted overlays in a viewport. |

|
View Detailed Segment Statistics |
|
| With 3.10, segment statistics are now automatically calculated and updated as you draw or modify segmentations. For each segment, OHIF computes values like volume, min/max voxel intensity, centroid location, and advanced PET-specific metrics such as SUVpeak. All processing runs smoothly in the background via Web Workers—no lag, no frozen UI. This was one of the most requested features, and it's designed to just work without getting in your way. |

|
|
|
Generate Bidirectional Measurement for Segments |
|
This new tool will automatically detect and create a bidirectional measurement in the largest area of a segment. This tool searches across all slices to find the largest bidirectional measurement, calculates it, and adds it directly to the viewport. |
|
|
|
|
|
|
|
|
|
|
|
|
Automatic Labelmap Slice Interpolation |
|
| We have added a new labelmap interpolation utility that fills in skipped slices between segmentations automatically. It uses morphological priors to generate smooth, consistent results across any plane. The process runs in the background, so you can keep working without interruption. |
|
|
|
|
|
|
|
|
|
|
|
|
|
| All panels in the Viewer are now fully resizable, featuring responsive and fluid components that ensure content, controls, and interface elements remain readable and easy to use at any width or screen configuration. These enhancements set the foundation for our upcoming multi-monitor and mobile designs, bringing greater flexibility and usability across all devices. |

Component Library & Migration |
|
 |
We’ve significantly upgraded our UI component library to enhance accessibility, functionality, and ease of implementation. Components have been redesigned and moved into a new streamlined library—@ohif/ui-next. This update provides improved organization and features an interactive showcase, letting users preview components in action before building. The Viewer part of the App has now been fully migrated to the new library, eliminating legacy components entirely. Next up: migrating the Study List.

Help Shape the New Study List Experience |
|
The Study List is the final area of the application still using the legacy interface, and we’re preparing to redesign it next. Our goals include making the Study List fully responsive, enhancing data handling, and introducing thumbnail support. Your insights are valuable—please share your feedback to help us create an improved and intuitive user experience. |

Showcase: Quantitative Imaging for Personalized Cancer Medicine |
|
Quantitative Imaging for Personalized Cancer Medicine is a contract research organization and imaging core lab at Techna Institute, University Health Network, Toronto, Canada. QIPCM provides a central repository to store imaging data for multi-center trials, a data ingestion pipeline to curate and perform quality assurance on images, and various tools for analyzing and viewing images in the repository. The OHIF Viewer is an integral tool in the workflow, and QIPCM has been a contributing member of the OHIF community for several years.
QIPCM is partnering with OHIF to contribute automated test modules to the OHIF viewer repository. The test coverage will contribute to an OHIF initiative aimed at increasing automated test coverage across the broader OHIF and Cornerstone ecosystem, including the creation of new test modules and the conversion of older tests onto the latest test platform. |

The Imaging Data Commons team has, as always, contributed to our projects. They introduced overlapping segment features and an enhanced DICOM tag browser modal. The Flywheel team was helpful in fixing bugs and making the OHIF viewer more customizable. We also appreciate the new, simplified annotation tracking mode they introduced. Pliny team added Doppler measurement support and sped up cine playback performance. The Better Medicine team contributed basic multi-monitor support, which is our initial step towards more advanced reading workflows. The University of Calgary team contributed the new hierarchical, tree-structured measurements to our panel measurements. They also kindly contributed resizable panels in the OHIF Viewer. The team from Freie Universität Berlin and the University of Calgary supported the development of multi-study load/save. The Carestream Dental Team really helped out by contributing the new arrow marker, adding a label tool for annotations, and adding support for the loading of various geometries in cornerstone3D.

 | The OHIF Viewer 3.11 release will build on the progress of previous versions by introducing advanced capabilities tailored to the needs of radiation therapy planning and multimodal imaging workflows. This iteration focuses on expanding clinical functionality through support for RT Dose overlays, enhanced RT Structure Set visualization, and improved data fusion controls. Alongside these key features, OHIF continues to evolve its architecture and user interface, furthering its mission to deliver a powerful, flexible, and intuitive platform for medical image viewing on the web.
