1. Overview |
This public dataset is released for the |
TopCoW (Topology-Aware Anatomical Segmentation of the Circle of Willis for CTA and MRA) challenge, |
to be held with the Medical Image Computing and Computer Assisted Intervention (MICCAI) conference in October 2024. |
2. Data Usage License |
Following the definitions of "https://opendata.swiss/en/terms-of-use" on open data use, |
the following license is chosen: |
"Terms of data use: |

By downloading the data, you agree with the license terms. |

3. Contents of Data |
The training data consist of |
- 250 (=125 pairs) CTA and MRA for TopCoW 2024 challenge |
- voxel annotations for CoW multi-class segmentation |
- bounding box annotations for CoW object detection |
- edge list annotations for CoW graph classification |
The training (Tr) data folder has the following sub-folders: |
* `imagesTr`: Angiographic scans in nifti format, 16-bit signed. LPS+ orientation |
* The nifti filenames are saved with schema: `topcow_{modality}_{pat_id}_0000.nii.gz` |
* `modality`: `mr` for MRA, `ct` for CTA |
* `pat_id`: patient ID, `001`, `002`, ... |
* `cow_seg_labelsTr`: Multi-class segmentation mask nifti with CoW anatomical labels |
* Voxel values for different CoW vessel segments: |
* 0: Background, 1: BA, 2: R-PCA, 3: L-PCA, 4: R-ICA, 5: R-MCA, 6: L-ICA, 7: L-MCA, 8: R-Pcom, 9: L-Pcom, 10: Acom,11: R-ACA, 12: L-ACA, 15: 3rd-A2 |
* `roi_loc_labelsTr`: Size and location info for the CoW region of interest (ROI) i.e. the 3D bounding box: |
* Text file containing the size and location of the 3D bounding box info |
* Size = number of pixels along the x, y, z axis |
* Location = coordinate of the x-min, y-min, z-min (0-indexed) |
* `antpos_edges_labelsTr`: Edge list of anterior and posterior edges of the CoW graph |
* Yml file indicating the presence of edges (0: absent, 1: present) |
* 4 edges for `anterior` part, roughly from left to right: |
* L-A1 |
* Acom |
* 3rd-A2 |
* R-A1 |
* 4 edges for `posterior` part, roughly from left to right: |
* L-Pcom |
* L-P1 |
* R-P1 |
* R-Pcom |
We also release 10 (=5 pairs) CTA and MRA from TopCoW challenge in folder `imagesVal` but without the accompanying annotations. |
The small validation set is intended to validate the docker submission technically and not counted towards the ranking. |
