RadioDINO-b16 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-b16 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.

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-b16", 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)
