Why MedTech Open Models

Built for medical imaging researchers and developers

01

Start from Strong Foundations

Foundation models pre-trained on large-scale medical datasets. Fine-tune on your data instead of training from scratch.

02

From 2D to 4D

CT, MRI, X-ray, ultrasound, and surgical video in one collection. Static images through dynamic physiology.

03

Synthetic Data Generation

Create synthetic volumes to augment training, simulate rare pathologies, and enable privacy-preserving data sharing across institutions.

04

Open Weights

Download from HuggingFace and run locally. No API keys, no cloud dependency. Apache 2.0 source code with model weights for commercial and research use.

05

Production Frameworks

Built on MONAI for medical imaging, Cosmos for world models, and Isaac for physical AI. Composable configs, reproducible pipelines.

06

Research to Deployment

Every model includes pre-trained weights, example configs, and documentation. Go from paper to inference with minimal setup.
