NVIDIA Clara Medical Imaging
Today, GPUs are found in almost all imaging modalities, including CT, MRI, x-ray, and ultrasound - bringing compute capabilities to the edge devices. With the boom of deep learning research in medical imaging, more efficient and improved approaches are being developed to enable AI-assisted workflows.
To develop these AI capable applications, the data needs to be made AI-ready. NVIDIA Clara’s AI-Assisted Annotation does so by providing APIs and a toolkit to bring AI-assisted annotation capabilities to any medical viewer. Post annotation, diverse and high quality annotated data is required to create powerful AI models. To enable this, NVIDIA Clara Train SDK includes privacy-preserving Federated Learning, a collaborative learning paradigm that enables research hospitals and institutions to collaborate and develop more robust AI algorithms without sharing private data.
to deliver all the necessary tools for healthcare application developers.
Clara Federated Learning
NVIDIA’s latest release of Clara Train SDK, which features Federated Learning, makes it possible for Academic Hospitals and centers of AI excellence to collaboratively build robust AI algorithms without compromising data privacy. From peer-to-peer to cyclic and server-client, Federated Learning can be implemented in different distributed architectures.
NVIDIA Clara’s implementation is based on a server-client approach, which means that a centralized server acts as a facilitator for the overall federated training with the participation of various clients. The client only shares partial model weights back to the server for aggregation - data stays secure at the client location. The configurable MMAR (Medical Model ARchive) feature of Clara Train SDK makes it possible for developers to bring their own models and components to perform Federated Learning and have control over whether local training is run on a single GPU or multiple GPUs.Learn More

- Federated learning is a collaborative learning technique that allows for distributed training with multiple clients. With Clara Train v2.0 we bring privacy-preserving Federated Learning that enables researcher to collaborate and build AI Models without sharing private data.
- Automatic Mixed Precision(AMP) allows researchers to train with half precision and maintain network accuracy. AMP can reduce memory usage and provide significant speed ups to training process.
- Deterministic training on GPUs is now available in the SDK and is crucial to guarantee reproducibility for iterative experimentation.
- The option to use Smart Cache in new task specific ImagePipelines allows for faster and more efficient training by saving intermediate results and skipping repeated operations.
- New loss functions and models have been added.
- Transforms have been rewritten to be more purpose based with ShapeFormat and MedicalImage taken into account to simplify configuration and improve clarity.
- You can use MMARs to set up training configurations with json, but you can directly use python code with the Clara Train API for greater customization including bringing your own components.
