Today, GPUs are found in almost all imaging modalities, including CT, MRI, X-ray, and Ultrasound - bringing compute capabilities from IT data centers and clouds 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, data scientists and researchers need to build a robust AI model. To enable this, NVIDIA Clara Train includes techniques like AutoML, privacy-preserving federated learning, and Transfer Learning. After training, you need to bring your model to the right clinical environments, and you can do this with NVIDIA Clara Holoscan. Clara Holoscan reduces engineering investment for building high-performance AI Inference Platforms.

Medical Imaging AI Workflow

NVIDIA Clara for Medical Imaging helps accelerate a typical imaging workflow that starts with labeling data, creating AI models, developing applications that include one or several AI models, and finalizing their deployment at an institution or across multiple institutions.

NVIDIA AI-Assisted Annotation (AIAA) with DeepGrow allows fast labeling of data with a few clicks on an area of interest and in a few slices for CT and MRI. AIAA helps speed up image labeling, which can be a time-consuming and tedious task prone to user variation.

NVIDIA Clara Train SDK provides over 20 pre-trained AI models for radiology and digital pathology that are ready to download and use immediately or be tailored to an institution’s data via the transfer learning toolkit or trained on various institutions’ data via our Federated Learning framework. With Federated Learning, a trained local model can be trained on diverse patient data across regions and institutions by sharing a subset of model weights without sharing patient information.

NVIDIA Clara Holoscan is a hybrid computing platform for medical devices that combines hardware systems, optimized libraries, SDKs, and core microservices needed to develop and run end-to-end streaming and imaging applications, from embedded to edge to cloud.

AI Model Training

Clara Train SDK

NVIDIA Clara Train SDK provides a training framework to help accelerate deep learning training and inference for medical imaging use cases. It allows medical imaging researchers and developers to implement new models using a high-level intuitive API quickly.

Clara Train is built on MONAI Core, a PyTorch-based framework for deep learning in healthcare imaging, and abstracts these domain-specialized build blocks from MONAI into MMAR (Medical Model Archive) format.

  • Provides state of the art pre-trained models to help you quickly get started
  • Increases the training performance by up to 50x with domain-specific GPU optimization for 3D Imaging model
  • Provides powerful techniques like AutoML, that enable automatic parameter tuning and make iterative experimentation faster.
  • Clara Train’s Federated Learning is powered by Nvidia's stanalone python library nvFlare that provides an easy way of provisioning distributed clients for multi-institutional collaboration for medical imaging use-case.

AI inference

Clara Holoscan SDK

NVIDIA Clara Holoscan SDK provides healthcare-specific acceleration libraries, pre-trained AI Models, and Reference Applications for computational medical devices in ultrasound, endoscopy, surgical robotics, digital pathology, radiation therapy, patient monitoring CT, MRI, X-ray, Genomics, Microscopy.

Clara Holoscan for traditional medical imaging inference use cases, including diagnosis, quality assurance and research validation, is still in development, you can learn more on the Holoscan SDK Page.

If you are looking to get started today, we encourage you to check out MONAI Deploy. It’s an open-source, easy-to-get-started set of SDKs, reference applications and microservices, created by the Project MONAI community.

MONAI Deploy

MONAI Deploy aims to become the de-facto standard for developing, packaging, testing, deploying, and running medical AI applications in clinical production. MONAI Deploy is focused on defining the journey from research innovation to clinical production environments in hospitals. The guiding principles are:

  • Create tangible assets: tools, applications, and demos/prototypes.
  • Radiology first, then other modalities like Pathology.
  • Interoperability with clinical systems. Starting with DICOM, then FHIR.
