# RadioDINO-s8

**RadioDINO-s8** is a self-supervised Vision Transformer foundation model developed for radiomics and medical imaging. It is based on the DINO framework and pretrained on the large-scale **RadImageNet** dataset (1.35 million CT, MRI, and Ultrasound images across 165 classes and 11 anatomical regions). This model is part of the *Radio DINO* family and was created to extract robust, general-purpose features for downstream medical tasks including classification, segmentation, and interpretability analysis.

Unlike traditional radiomics methods that rely on handcrafted features and supervised models pretrained on natural images, RadioDINO-s8 offers a domain-adapted alternative that consistently outperforms previous models on diverse medical benchmarks. It has been rigorously validated on the MedMNISTv2 benchmark suite and shown to be effective even without fine-tuning.

## Model Details

- **Architecture:** ViT-small with patch size 8 (`s8`)
- **SSL framework:** DINO (self-distillation without labels)
- **Pretraining dataset:** RadImageNet (1.35M CT/MRI/Ultrasound images)
- **Embedding size:** 384
- **Applications:** Feature extraction, classification backbones, transfer learning, medical imaging analysis

## Example Usage

```python
from PIL import Image
from torchvision import transforms
import timm
import torch

# Load model from Hugging Face Hub
model = timm.create_model("hf_hub:Snarcy/RadioDino-s8", pretrained=True)
model.eval()
device = "cuda" if torch.cuda.is_available() else "cpu"
model.to(device)

# Load and preprocess a sample image
image = Image.open("path/to/your/image").convert("RGB")
transform = transforms.Compose([
    transforms.Resize((224, 224)),
    transforms.ToTensor(),
    transforms.Normalize(mean=[0.485, 0.456, 0.406],
                         std=[0.229, 0.224, 0.225]),
])
input_tensor = transform(image).unsqueeze(0).to(device)

# Forward pass to obtain feature embedding
with torch.no_grad():
    embedding = model(input_tensor)

```
