Key Questions Answered
What are the steps to deploy the NVIDIA Clara Deploy QuickStart VM?
The deployment involves three main steps: first, deploy a clean Ubuntu Linux 18.04 VM; second, run the installation scripts using Ansible to configure the Clara Deploy platform; and third, trigger the inference pipeline to visualize results using the embedded web client.
How does Clara Deploy integrate with healthcare information systems?
Clara Deploy supports industry standards such as DICOM for ingesting input data and publishing inference results, allowing seamless integration with external PACS systems for efficient data handling and processing.
What hardware requirements are needed for deploying Clara VM?
The recommended hardware includes a system with a passthrough NVIDIA GPU (T4, V100, or A100), 16 vCPUs, 32 GB RAM, and a 500-GB disk, ensuring adequate resources for running AI inference tasks.
What results can be visualized after running the COVID-19 segmentation pipeline?
After processing, the results include lung segmentation, lung lesion segmentation, and two DICOM reports that detail the findings from the COVID-19 CT study, which can be viewed in the Orthanc and OHIF interfaces.
