NVIDIA Clara™ is a computational platform that makes it easy for developers to build, manage, and deploy intelligent medical imaging workflows and instruments. From improving processing speed and image quality to AI enabled clinical workflows, medical imaging developers are adopting the Clara platform to improve patient outcomes and reduce the cost of care.

Medical imaging industry is being transformed by two technology trends - Artificial Intelligence and Software defined workflows. A decade ago, one of the earliest applications to take advantage of GPU computing was image reconstruction. Today, GPUs are found in almost all imaging modalities, including CT, MRI, X-ray, and Ultrasound. Clara Imaging brings together accelerated libraries and deployment frameworks to create and upgrade Intelligent Imaging Instruments.

Deep Learning research in Medical Imaging is also booming with more efficient and improved deep learning based approaches being developed to enable AI-assisted workflows. However, most of this AI research today 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 production clinical workflow. With the latest release of Clara AI now Data Scientists & Software developers have necessary tools, APIs and development framework to train and deploy production quality AI.

Platform Stack

NVIDIA Clara AI technology stack includes systems software libraries that form the foundation of GPU computing and abstracted software tools, containers, and workflow defining pipelines that allow data scientist and medical imaging experts to build and deploy AI for clinical workflows as well as accelerated research in Medical Imaging.

Clara Train SDK enables data scientists and medical researchers to focus on what matters most to them instead of going through the time consuming and resource intensive process of building neural networks from scratch. The Clara Train SDK offers state of the art tools and technologies that accelerate deep learning training for medical imaging. You can benefit from NVIDIA deep learning expertise out of the box.

The Clara Train SDK consists of two components:

  • AI-Assisted Annotation: AI-Assisted Annotation enables fast labeling of 3D volume data and automatic annotation with the help of NVIDIA provided pre trained models for organs trained on public dataset allowing radiologists to annotate much faster and eliminates having to label every slice of CT and MRI data.
  • Domain specific Transfer Learning: simplifies deep learning tasks such as segmentation of 3D CT/MRI images and enables researchers to train or fine tune models and export to NVIDIA TensorRT based inference with easy to use python wrappers. Also provided are several pre-trained models unique to medical imaging. The 3-D Brain Tumor segmentation model developed by NVIDIA researchers won first place for Multimodal Brain Tumor Segmentation Challenge 2018. This and several other models developed by NVIDIA researchers for brain tumor segmentation, liver and lesion segmentation, spleen segmentation etc. are available to use with Clara Train SDK.

Key Features of Clara Train SDK:

  • Assisted Annotation - Takes approximate points as input and returns a list of slices already annotated for different organs.
  • Performance Speedup - Achieve 4X-10X speedup compared to manual editing depending on the organ being segmented.
  • Polygon Editing - Reduces time in correcting annotation results by suggesting organ boundaries automatically.
  • Annotation Client: example code demonstrates integrating SDK into third party applications showing API functionality. The Medical Imaging Interaction Toolkit (MITK) is a free open-source software system for development of interactive medical image processing software.

  • Utilities - Helper classes to assist in the integration efforts on the client side for third party applications for AI Assisted Annotation.
  • Transfer Learning Workflow - Easy to use model adaptation and retraining for heterogeneous multi-GPU environments.
  • Configuration files that can be modified easily to add classes to models.
  • Configurable framework to simplify deep learning tasks such as 3D segmentation from CT/MRI images or 2D classification
  • Model export API for easier deployment of applications to TensorRT based inference and via Clara Deploy SDK
  • Kubeflow pipeline to quickly execute a segmentation training workflow on Kubernetes based environments

"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.
