Tool for segmentation of over 117 classes in CT images. It was trained on a wide range of different CT images (different scanners, institutions, protocols,...) and therefore should work well on most images. A large part of the training dataset can be downloaded from Zenodo (1228 subjects). You can also try the tool online at

This tool is offered as it is. It will compact the output parameters in a single file and include statistics and radiomics as separate files.
