## 3. Clinical Applications
This model is intended for research purposes and clinical decision support. It should not be used as a standalone diagnostic tool. Always consult qualified healthcare professionals for medical diagnoses.

## 4. How to Run Locally

Please refer to our code repository for more information about running MedVision-DiagNet locally.

### Model Loading
```python
from transformers import ViTForImageClassification, ViTImageProcessor

model = ViTForImageClassification.from_pretrained("username/MedVision-DiagNet")
processor = ViTImageProcessor.from_pretrained("username/MedVision-DiagNet")
```

### Inference
```python
from PIL import Image

image = Image.open("medical_scan.png")
inputs = processor(images=image, return_tensors="pt")
outputs = model(**inputs)
predictions = outputs.logits.argmax(-1)
```

### Preprocessing Recommendations
For optimal performance:
- Input resolution: 224x224 or 384x384
- Normalization: ImageNet standards (mean=[0.485, 0.456, 0.406], std=[0.229, 0.224, 0.225])
- DICOM images should be converted to PNG/JPEG with appropriate windowing
