Clara Medical Imaging is a collection of developer toolkits built on NVIDIA’s compute platform aimed at accelerating compute, artificial intelligence, and advanced visualization. Medical imaging industry is being transformed. A decade ago, the earliest applications to take advantage of GPU computing were image & signal processing applications.

Today, GPUs are found in almost all imaging modalities, including CT, MRI, X-ray, and Ultrasound bringing more compute capabilities to the edge devices. Deep Learning research in Medical Imaging is also booming with more efficient and improved approaches being developed to enable AI-assisted workflows.Today, most of this AI research is being done in isolation and with limited datasets which may lead to overly simplified models. Even when a fully validated model is available, it is a challenge to deploy the algorithm in a local environment. With the latest release of Clara AI for Medical Imaging now data scientists, researchers and software developers have the necessary tools, APIs and development framework to train and deploy AI workflows.

Clara Train SDK enables data scientists and medical researchers with state of the art tools and technologies that accelerate data annotation, adaptation and development of AI models for Medical Imaging workflows.

Key Capabilities of Clara Train SDK include:

  • APIs to add AI-assisted annotation to any medical viewer with new features like Auto-Annotation and interactive annotation modes, Annotation Server which makes pre-trained models available to the client application and client APIs hosted on Github that make integration with your Medical viewer application seamless.
  • The SDK provides capabilities to use techniques like Transfer learning to adapt or train deep learning models from scratch, enabling Data Scientists to bring their own model architectures and run workflows, this is made possible through a unified foundation of Medical Model Archive (MMAR)
  • The MMAR (Medical Model Archive) provides a model development environment; defines a standard structure for storing and organizing all artifacts produced during the model development life cycle.
  • MMAR includes NVIDIA pretrained models based on AH-Net, DenseNet, ResNet, Dextr3D packaged as complete 2D/3D model applications for organ based segmentation, classification and annotation.

Key Features of Clara Train SDK 1.1

  • Bring Your Own Models, Transforms, Readers, Losses and Metrics - Learn More
  • Configurable framework to simplify deep learning tasks from medical images.
  • Medical Model Archives (MMAR) including deep learning models and artifacts.
  • Model adaptation and retraining that is easy to use in heterogeneous multiple GPU environments.
  • Model Export API for easier deployment of applications to TensorRT based inference.

"We were able to get our hands on NVIDIA’s AI Assisted Annotation technology and integrate it into our viewer in a couple of days’ time. We currently annotate a lot of images - sometimes on the order of 1000 or more a day, so any technology that can help automate this process could potentially have a significant impact in reducing the time and cost of annotation. We are excited to leverage the AI assisted workflows and work with NVIDIA to solve these critical medical imaging problems."

— Mark Michalski, Executive Director at MGH & BWH Center for Clinical Data Science

Clara Deploy SDK provides a container based development & deployment framework for building AI accelerated medical imaging workflows, it uses Kubernetes under the hood and enables developers and data scientists to define a multi-staged container based pipeline.The modular architecture allows developers to use the offerings of the platform end-end or customize the workflow pipelines with bring-your-own algorithms.

The capabilities forming the Clara Deploy SDK include:

  • Data Ingestion interface to communicate to Hospital PACs system
  • Cores services for orchestrating and managing resources for workflow deployment and development
  • Reference AI applications that can be used as-is with user defined data or can be modified with user-defined-AI algorithms
  • Lastly, Clara Deploy framework also includes Visualization capabilities to monitor progress and view final results
