Dataset

 

The test data set is consisting of one enhanced CT scan, several unenhanced CT scans with different levels of breathing and cardiac phase. A binary lung mask of the enhanced CT scan is provided.  In all situations the enhanced CT scan is marked as the reference standard. The displacement field is showing the geometry of the enhanced CT scan were each voxel is pointing towards the unenhanced CT scan. It is possible to download an example input scans (training set) for registration. A displacement field of the Z direction of an tested algorithm is also given in the training set.
