This file regroups the 5675 synthetic femurs used and described in the paper: "Enhanced segmentation of femoral bone metastasis in CT scans of patients using synthetic data generation with 3D diffusion models" Saillard et al. Three repositories are needed to form the full archive. When all are downloaded, they can be deflated with the following bash command : cat Generated_3DCT_Metastatic_Femurs.tar.gz* | tar faxv - This is the first part (1/3) part 2/3: 10.5281/zenodo.13824177 part 3/3: 10.5281/zenodo.13824179 Generated CT Scans are organized in two directories: one for files generated with DDPM this one) and one without DDPM. ├── Generated_3DCT_Metastatic_Femurs_with_DDPM │ ├── img│ ├── lbl│ └── msk └── Generated_3DCT_Metastatic_Femurs_NO_DDPM ├── img ├── lbl └── msk The content of each directory is as follows: img : the generated 3D CT scan (nii.gz format) from the 26 healthy femurs lbl : the lesions segmentation (nii.gz format) of the generated 3D CT scan msk : the segmentations of the 26 healthy femurs (nii.gz) A given filename corresponds to in img and lbl directories : ./lbl/MEK03les0MEK14.nii.gz is the lesions segmentation of ./img/MEK03les0MEK14.nii.gz. ./lbl/MEK03les197MEK28.nii.gz is the lesions segmentation of ./img/MEK03les197MEK28.nii.gz But in msk, the corresponding femur mask for these examples is ./msk/MEK03.nii.gz
