trame-slicer 0.5.0

trame-slicer library

trame-slicer

trame-slicer is a Python library bringing 3DSlicer components in trame as a composable library.

It uses 3D Slicer's python wrapping and adds a thin wrapping to make it available with the trame framework.

Warning

As the 3D Slicer Python wheel is not yet generated by the 3D Slicer CI, manually generated wheels are provided for Python 3.10 for Windows and Linux WSL.

The API has not been stabilized / reviewed by the 3D Slicer core developers so please use this library with caution.

Installing

The library can be installed as follows :

• Setup a Python 3.10 environment
• Activate your environment
• Git clone the library
• cd into the library
• Use the [pip install -e . command]{.title-ref} to install the library along it's dependencies
• Copy the vtk_mrml wheel file matching your OS
• Pip install the wheel using the find links command (see below)

pip install -e .
pip install vtk_mrml-9.4.0-cp310-cp310-win_amd64.whl  --find-links . # Windows
pip install vtk_mrml-9.4.0-cp310-cp310-manylinux_2_35_x86_64.whl  --find-links . # Linux WSL

Getting started

To get started using trame, please have a look at the introductory trame course.

To start using the trame-slicer library, have a look and run the medical viewer app

Features

The following subset of 3D Slicer features are currently supported :

• (limited) file loading
• Volume files (DCM, NRRD, NIFTI, ...)
• Model files (STL, OBJ)
• MRML / MRB files
• Segmentations (NRRD, NIFTI, ...)
• Display
  • 2D/3D with 3D Slicer UI manipulation
  • Volume Rendering preset / shift
• Bare bone access to 3D Slicer MRML scene and Core logic components

Work in progress

To make it easier for users to use trame-slicer, the following work are in progress :

• Slicer wheel generation merge into 3D Slicer's preview release
• CI changes to build the Slicer wheel along 3D Slicer's release
• 3D Slicer extension to install trame-slicer and launch a trame-slicer server directly from 3D Slicer

Troubleshooting

If you get the following error:

ImportError: cannot import name 'vtkMRMLDisplayableNode' from 'slicer' (XXX/lib/python3.10/site-packages/slicer/__init__.py)

You might be using a statically compiled Python. Please switch to a shared version of Python.
