MONAI

MONAI (Medical Open Network for AI) is a niche but critical framework for the medical AI ecosystem. Built on PyTorch, it provides the standardized tools researchers need to build their own medical AI models.

### Why it's the Standard
* **Domain-Specific**: Includes pre-built components for 3D image transformation, segmentation (identifying tumors), and classification that are specific to medical data (DICOM files).
* **Pre-trained Models**: Offers access to a "Model Zoo" of models already trained on massive medical datasets, allowing researchers to skip the "cold start" phase.
* **Collaborative**: Supported by Nvidia and major academic centers, ensuring it remains the cutting-edge tool for medical AI development.

**Best for**: Academic researchers and in-house data science teams at hospitals building custom diagnostic software.
