XDRT (XDR Toolkit) is a python toolkit to work with the Elekta XDR and XVI file formats.

Project description

XDRT (XDR Tools)

pypi

XDRT is a python toolkit to work with the XDR file format used e.g. by Elekta to store cone-beam CT images and as reconstructed by XVI. The reading of .xvi files is also supported, allowing to find the map the XDR file to the moment of acquistion (which fraction, what type of scan).

Features

  • Utilities to read (compressed) 3D and 4D XDR files in python.
  • Ability to read XVI files and link planning scans with cone-beam CT scans.
  • xdr2img command line utility to convert xdr images to ITK supported formats.
  • xvi2img command line utility converts all fractions to ITK supported formats.

How to use

The package needs to compile the decompression library, which can be done with: python setup.py install or with pip install git+https://github.com/NKI-AI/xdrt.git or from PyPi using pip install xdrt.

  • The command line program xdr2img image.xdr image.nrrd converts images from XDR to any ITK supported format. For more details check xdr2img --help.
  • The command line program xvi2img reads XVI files and combined with the XDR files, writes to a new directory and image format. For more details check xvi2img --help.

Work in progress

This package is work in progress, if you have an image which is not properly parsed by xdrt, create an issue with the image and expected output.

The following is not yet supported:

  • Origin is not yet always properly parsed.
  • Only uniform grids are currently supported.
  • Protocol is not detected from the XVI file (e.g. 4D-CBCT + SBRT). Images in fraction are output consecutively.

Create an issue if this is an urgent issue for you.
