Liver Phantom Indentation
This dataset was obtained from an indentation experiment with a soft silicon liver phantom. The volumetric displacement field inside the phantom was obtained by tracking 117 small teflon balls using CT images. The dataset can be used to evaluate soft tissue registration algorithms.
1. The original CT data of the phantom with different indentation depths (Liver07.vtk is the undeformed configuration, while Liver28.vtk is the CT image of the completely deformed phantom) in the .vtk file format.
2. The 117 marker inside the liver as vtk polydata. The different polydata files (MarkerDisp_Liver07.vtk - MarkerDisp_Liver28.vtk) are registered, i.e. corresponding points have the same id. The marker displacements can serve as the ground truth for the validation.
3. Surface models of the deformed and the undeformed phantom in very high resolution and low resolution. These surface models can be used as input for surface based registration algorithms or to build FE-models for registration purposes.
