</p>
</h2>


We introduce Curia, a foundation model trained on the entire cross-sectional imaging output 
of a major hospital over several years—which to our knowledge is the largest such corpus of 
real-world data—encompassing 150,000 exams (130 TB).  On a newly curated 19-task external validation benchmark, 
Curia accurately identifies organs, detects conditions like brain hemorrhages and myocardial infarctions, 
and predicts outcomes in tumor staging. Curia meets or surpasses the performance of radiologists and recent 
foundation models, and exhibits clinically significant emergent properties in cross-modality, and low-data regimes.

## 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")
```

You can also load the image pre-processor

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


Then to forward an image:


```python
img = np.random.rand(-1024, 1024, size=(256, 256)) # 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
```

## Loading model with heads

The following heads are available:
```abdominal-trauma
anatomy-ct
anatomy-mri
atlas-stroke
covidx-ct
deep-lesion-site
emidec-classification-mask
ich
ixi
kits
kneeMRI
luna16-3D
neural_foraminal_narrowing
oasis
spinal_canal_stenosis
subarticular_stenosis
```

To load the head, specify its name when loading the model

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

model = AutoModelForImageClassification.from_pretrained(
    "raidium/curia", subfolder="anatomy-ct", trust_remote_code=True
)
```
You can find the class of each label in `id_to_labels.json`
