We believe research on deformable image registration (DIR) of the lungs will greatly benefit from making image and validation data publicly available. Several 4D CT data sets, acquired at the Léon Bérard Cancer Center, can be downloaded here for use in your research. Along with the images, we provide large sets of manually identified landmarks, allowing you to validate your motion estimation.
We welcome all suggestions that can make this data more useful for you. David Sarrut, david.sarrut[at]creatis.insa-lyon.fr
This data set includes:
- Six 4D CT data sets
- 100 landmarks in the inhale and exhale frame.
- For 3 patients, landmarks are also available in all intermediate frames.
