MONAI Label

MONAI Label is a server-client system that facilitates interactive medical image annotation by using AI. It is an open-source and easy-to-install ecosystem that can run locally on a machine with one or two GPUs. Both server and client work on the same/different machine. However, initial support for multiple users is restricted. It shares the same principles with MONAI.

3D Slicer

Download Preview Release from https://download.slicer.org/ and install MONAI Label plugin from Slicer Extension Manager.

Refer 3D Slicer plugin for other options to install and run MONAI Label plugin in 3D Slicer.

To avoid accidentally using an older Slicer version, you may want to uninstall any previously installed 3D Slicer package.

OHIF

MONAI Label comes with pre-built plugin for OHIF Viewer.

Please install Orthanc before using OHIF Viewer. For Ubuntu 20.x, Orthanc can be installed as apt-get install orthanc orthanc-dicomweb. However, you have to upgrade to latest version by following steps mentioned here

You can use PlastiMatch to convert NIFTI to DICOM

OHIF Viewer will be accessible at http://127.0.0.1:8000/ohif/

NOTE: OHIF does not yet support Scribbles-based annotations.
