This dataset is released in conjunction with the paper "VoDaSuRe: A Large-Scale Dataset Revealing Domain Shift in Volumetric Super-Resolution"

-
The VoDaSuRe dataset consists of 32 volumetric scans of 16 samples acquired using laboratory CT (Lab-CT). It includes:
|
| 4 |
-
- High-resolution (HR) volumes
|
| 5 |
-
- Low-resolution (LR) volumes (unregistered)
|
| 6 |
-
- Registered and intensity-matched low-resolution (REG) volumes
|

The dataset contains training and test splits stored under the "ome/train" and "ome/test" subfolders.
|
| 16 |
-
|
| 17 |
-
All data is stored in the OME-Zarr format, a hierarchical, chunked storage format that supports efficient and lazy loading.
|

|

Each .zarr file has the following structure:

-
|
| 42 |
-
Alternatively, the data can be easily fetched through the command line, for example with:
|
| 43 |
-
> wget https://archive.compute.dtu.dk/downloads/public/projects/VoDaSuRe
|
| 44 |
-
|
| 45 |
-
The data should be decompressed before use:
|
| 46 |
-
> cd VoDaSuRe && bash extract_files.sh
|
| 47 |
-
|
| 48 |
-
Note: The full dataset requires approximately 500 GB of disk space.
