### Dataset Download

I created a convenient PNG-formatted version of the ACDC dataset.  
This version was converted from the files provided in the SSL4MIS repository:  
[SSL4MIS ACDC Version](https://github.com/HiLab-git/SSL4MIS/tree/master/data/ACDC)
 
If you use the dataset in your research, please make sure to cite the **original ACDC paper**.

### Dataset Structure

```bash

├── train-label/                # Labeled training set
│   ├── image/                  # Input images (.png)
│   └── mask/                   # Corresponding segmentation masks (.png)

├── train-unlabel/              # Unlabeled training set
│   └── image/                  # Images without ground truth masks
