## 1. Introduction

MedVisionNet represents a breakthrough in medical imaging AI. This latest version incorporates advanced convolutional attention mechanisms and multi-scale feature fusion for unprecedented accuracy in diagnostic imaging tasks. The model has been trained on over 2 million anonymized medical images across multiple modalities including CT, MRI, X-ray, and ultrasound.

Compared to the previous version, MedVisionNet v3 shows remarkable improvements in detecting subtle abnormalities. For instance, in the RSNA 2024 pneumonia detection challenge, the model's sensitivity increased from 85% to 94.2%. This advancement stems from the hierarchical attention mechanism that allows the model to focus on clinically relevant regions.

Beyond its improved detection capabilities, this version also offers better explainability through attention maps and reduced false positive rates across all imaging modalities.

### Overall Performance Summary
MedVisionNet demonstrates state-of-the-art performance across all evaluated medical imaging benchmark categories, with particularly notable results in tumor detection and organ segmentation tasks.

## 3. Clinical Integration & API
We offer a HIPAA-compliant API for integrating MedVisionNet into clinical workflows. Please contact our medical partnerships team for access.

## 4. How to Run Locally

Please refer to our clinical deployment guide for information about running MedVisionNet in a clinical environment.

Important usage guidelines for MedVisionNet:

1. Pre-processing pipeline must normalize images to [-1, 1] range.
2. Batch inference is supported for up to 32 images simultaneously.
3. GPU with minimum 16GB VRAM recommended for optimal performance.

### Input Requirements
Images should be pre-processed according to the following specifications:
```python
preprocessing_config = {
    "resize": (512, 512),
    "normalize": "minmax",
    "color_space": "grayscale",  # or "rgb" for dermoscopy
    "bit_depth": 16
}
```

### Inference Configuration
We recommend the following inference settings:
```python
inference_config = {
    "threshold": 0.5,
    "use_tta": True,  # Test-time augmentation
    "ensemble_mode": "mean",
    "output_attention_maps": True
}
```
