</h2>


We introduce Curia-2, a follow-up to Curia which significantly improves the original pre-training strategy and representation quality to better capture the specificities of radiological data. Curia-2 excels on vision-focused tasks and fairs competitively to vision-language models on clinically complex tasks such as finding detection.

Research paper coming soon.



## Loading the model

To load the model, use the `AutoModel` class from huggingface transformers library.

```python
from transformers import AutoModel
model = AutoModel.from_pretrained("raidium/curia-2")
```

You can also load the image pre-processor

```python
from transformers import AutoImageProcessor
processor = AutoImageProcessor.from_pretrained("raidium/curia-2", trust_remote_code=True)
```


Then to forward an image:


```python
img = 2048 * np.random.rand(256, 256) - 1024 # single axial slice, in PL orientation
model_input = processor(img)
features = model(**model_input)
```

The image must follow the following format:
```
input: numpy array of shape (H, W)
  Images needs to be in:
  - PL for axial
  - IL for coronal
  - IP for sagittal
  for CT, no windowing, just hounsfield or normalized image
  for MRI, similar, no windowing, just raw values or normalized image
```

## License

The model is released under the RESEARCH-ONLY RAIL-M license.
