## 1. Introduction

MedVisionAI represents a breakthrough in medical imaging analysis. The latest version incorporates advanced vision transformer architectures optimized for chest X-ray, CT scan, and MRI interpretation. The model has been trained on over 2 million anonymized medical images from partnering hospitals worldwide.

<p align="center">
  <img width="80%" src="figures/fig3.png">
</p>

In rigorous clinical validation studies, MedVisionAI demonstrated significant improvements over previous versions. On the ChestX-ray14 benchmark, the model achieved a 94.2% AUC for detecting pneumonia, compared to 87.3% in the previous release. This improvement stems from enhanced attention mechanisms that better capture subtle radiological patterns.

Beyond diagnostic accuracy, MedVisionAI now offers reduced false-positive rates and improved explainability through attention map visualizations.

### Overall Performance Summary
MedVisionAI demonstrates exceptional performance across all medical imaging evaluation categories, with particularly strong results in critical finding detection and diagnostic accuracy.

## 3. Clinical Integration & API Platform
We provide HIPAA-compliant API access for healthcare institutions. Contact our medical partnerships team for integration details.

## 4. How to Run Locally

Please refer to our clinical documentation for deployment guidelines in healthcare settings.

Important deployment considerations for MedVisionAI:

1. DICOM format input is fully supported.
2. The model requires GPU acceleration for real-time inference.

The model architecture is based on Vision Transformer (ViT-Large) with medical imaging-specific adaptations.

### Input Format
MedVisionAI accepts medical images in the following formats:
```
Supported formats: DICOM, PNG, JPEG
Recommended resolution: 512x512 or higher
Color space: Grayscale or RGB
```

### Inference Example
```python
from medvision import MedVisionAI

model = MedVisionAI.from_pretrained("medvision/MedVisionAI")
result = model.analyze(image_path="chest_xray.dcm")
print(result.findings)
```

### Temperature
For diagnostic confidence calibration, we recommend setting the temperature parameter $T_{model}$ to 0.3.

### Integration with PACS Systems
For PACS integration, use the following configuration template:
```
pacs_config = {
    "ae_title": "MEDVISION_AI",
    "port": 11112,
    "storage_scp": true,
    "auto_routing": true
}
```

For real-time analysis pipelines, we recommend the following template:
```
analysis_pipeline = '''
1. Receive DICOM image from PACS
2. Preprocess and normalize image data
3. Run MedVisionAI inference
4. Generate structured report
5. Send results to referring physician
6. Archive analysis in long-term storage
'''
```
