Release Notes
New
OHIF-v3architecture has made OHIF a general purpose extensible medical imaging platform, as opposed to a configurable viewer.
What's new in OHIF-v3#
OHIF-v3 is our second try for a React-based viewer, and is the third version
of our medical image web viewers from the start. The summary of changes include:
- Addition of workflow modes
- Often, medical imaging use cases involves lots of specific workflows that re-use functionalities. We have added the capability of workflow modes, that enable people to customize user interface and configure application for specific workflow.
- The idea is to re-use the functionalities that extensions provide and create a workflow. Brain segmentation workflow is different from prostate segmentation in UI for sure; however, they share the segmentation tools that can be re-used.
- Our vision is that technical people focus of developing extensions which provides core functionalities, and experts to build modes by picking the appropriate functionalities from each extension.
- UI has been completely redesigned with modularity and workflow modes in mind.
- New UI components have been built with Tailwind CSS
- Redux store has been removed from the viewer in favour of services backed by React's Context API
