Clara Deploy AI COVID-19 Classification Pipeline

CAUTION: This is NOT for diagnostics use.

This asset requires the Clara Deploy SDK. Follow the instructions on the\nClara Ansible page\nto install the Clara Deploy SDK.

DISCLAIMER

This inference pipeline was developed by NVIDIA. It is based on a segmentation and classification model developed by NVIDIA researchers in conjunction with the NIH. The Software is for Research Use Only. Software’s recommendation should not be solely or primarily relied upon to diagnose or treat COVID-19 by a Healthcare Professional. This research use only software has not been cleared or approved by FDA or any regulatory agency

This reference pipeline is designed to infer the probability of COVID-19 infection with the chest CT scan of a patient. A 3D lung segmentation model as well as a 3D classification model are used in this pipeline. A single aixial DICOM series of chest CT scan is the pipeline input, and the final output is the report of the probabilities of COVID-19 and non-COVID-19.

Once the DICOM instances are received, the pipeline is triggered to first convert the DICOM instances to a volume image in MetaImage format. This image is then used as the input to two segmentation operators concurrently, the lugn segmentation and the COVID-19 lesion segmentation. Each segmentation operator performs inference using its own segmentation AI model, and generates a labeled segmentation as a binary mask on each slice of the volume, with the lung or lung lesion labeled as 1, and the background labeled as 0.

In the next step, the original volume image along with the labeled segmentation image are used by the COVID-19 classification operator to infer the probabilities of COVID-19 using the COVID-19 classification model.

The volume images generated by the COVID-19 lesion segmentation operator and the lung segmentation operator are also used to as inputs to a volume ratio metrics operator, which calculates and saves the lesion to lung ratio.

The pipeline generates the following outputs:

Lung segmentation image in MetaImage format
COVID-19 lesion segmentation image in MetaImage format
A new DICOM series for the lung segmentation image, optionally sent to a DICOM device
A new DICOM series for the COVID-19 lesion segmentation image, optionally sent to a DICOM device
A new DICOM series of Encapsulated PDF for the AI classification results, optionally sent to a DICOM device
A new DICOM series of Encapsulated PDF for the COVID-19 lesion to lung ratio results, optionally sent to a DICOM device
The original and lung segmentation volumes in MetaImage format to the Clara Deploy Render Server.
The original and COVID-19 lesion segmentation volumes in MetaImage format to the Clara Deploy Render Server.

Pipeline Definition

This pipeline is defined in the Clara Deploy pipeline definition language. It utilizes built-in reference containers to construct the following set of operators:

The dicom-reader operator converts input DICOM data into volume images in MetaImage format format.
The lung segmentation operator performs AI inference against the NVIDIA Triton Inference Server to generate segmentation volume images.
The COVID-19 lesion segmentation operator performs AI inference against the NVIDIA Triton Inference Server to generate segmentation volume images.
The classification operator performs AI inference against the NVIDIA Triton Inference Server to infer the probability of COVID-19.
The COVID-19 lesion to lung volume ratio operator.
The dicom-seg-writer converts the lung segmentation volume image into a DICOM SEG instance with a new series instance UID but the same study instance UID of the original DICOM.
The register-dicom-output operator registers the lung DICOM SEG instance with the Clara Deploy DICOM Adapter which in turn stores the instance on external DICOM devices per configuration.
The dicom-seg-writer for COVID-19 lesion converts the COVID-19 lesion segmentation volume image into a DICOM SEG instance with a new series instance UID but the same study instance UID of the original DICOM.
The register-dicom-output operator for COVID-19 lesion registers the lesion DICOM SEG instance with the Clara Deploy DICOM Adapter which in turn stores the instance on external DICOM devices per configuration.
The dicom-report-writer converts the AI classification results into DICOM Encapsulated PDF instances with a new series instance UID but the same study instance UID of the original DICOM.
The dicom-report-writer for volume ratio metrics converts the COVID-19 lesion to lung volume ratio metrics into a DICOM Encapsulated PDF instances with a new series instance UID but the same study instance UID of the original DICOM.
The register-dicom-report operator registers the DICOM Encapsulated PDF with the Clara Deploy DICOM Adapter which in turn stores the instance on external DICOM devices per configuration.
The register-volume-images-for-rendering operator registers original and segmented volume images with the Clara Deploy Render Server for visualization.

The following is the details of pipeline definition, with comments describing each operator's functions\nas well as input and output.

Follow the instructions on the\n[Clara Bootstrap](https://ngc.nvidia.com/catalog/model-scripts/nvidia:clara:clara_bootstrap) page\nto install the Clara Deploy SDK.\n\n## DISCLAIMER\n\nThis inference pipeline was developed by NVIDIA. It is based on a segmentation and classification model developed by NVIDIA researchers in conjunction with the NIH. The Software is for Research Use Only. Software’s recommendation should not be solely or primarily relied upon to diagnose or treat COVID-19 by a Healthcare Professional. This research use only software has not been cleared or approved by FDA or any regulatory agency\n\n---\n\nThis reference pipeline is designed to infer the probability of COVID-19 infection with the lung CT scan of a patient. A 3D lung segmentation model as well as a 3D classification model are used in this pipeline. A single aixial DICOM series of lung CT scan is the pipeline input, and the final output is the probabilities of COVID-19 and non-COVID-19 in csv format.\n\nOnce the DICOM instances are received, the pipeline is triggered to first convert the DICOM instances to a volume image in [MetaImage format](https://itk.org/Wiki/ITK/MetaIO/Documentation). This image is then used as the input to the lung segmentation operator which performas inference using the segmentation AI model, and generates a labeled segmentation as a binary mask on each slice of the volume, with the lung labeled as 1, and the background labeled as 0. In the next step, the original volume image along with the labeled segmentation image are used by the COVID-19 classification operator to infer the probabilities of COVID-19 using the COVID-19 classification model.\n\nThe pipeline generates the following outputs:\n- Lung segmentation image in [MetaImage format](https://itk.org/Wiki/ITK/MetaIO/Documentation)\n- A new DICOM series for the segmentation image, optionally sent to a DICOM device\n- Probabilities of COVID-19 and non-COVID-19 in csv format \n- The original and segmented volumes in [MetaImage format](https://itk.org/Wiki/ITK/MetaIO/Documentation) to the Clara Deploy\nRender Server for visualization.\n\n## Pipeline Definition\n\nThis pipeline is defined in the Clara Deploy pipeline definition language. It utilizes built-in reference containers to construct the following set of operators:\n\n- The dicom-reader operator converts input DICOM data into volume images in [MetaImage format](https://itk.org/Wiki/ITK/MetaIO/Documentation) format.\n- The segmentation operator performs AI inference against the NVIDIA [Triton Inference Server](https://docs.nvidia.com/deeplearning/sdk/triton-inference-server-guide/docs/index.html), formerly known as TRTIS, to generate segmentation volume images.\n- The classification operator performs AI inference against the NVIDIA [Triton Inference Server](https://docs.nvidia.com/deeplearning/sdk/triton-inference-server-guide/docs/index.html) to infer the probability of COVID-19. \n- The dicom-writer converts the segmented volume image into DICOM instances with a new series instance UID but the same study instance UID of the original DICOM.\n- The register-dicom-output operator registers the DICOM instances with the Clara Deploy DICOM Adapter which in turn stores the instance on external DICOM devices per configuration.\n- The register-volume-images-for-rendering operator registers original and segmented volume images with the Clara Deploy Render Server for visualization.\n\nThe following is the details of pipeline definition, with comments describing each operator's functions\nas well as input and output.\n\n```yaml\napi-version: 0.4.0\nname: COVID-19-pipeline\noperators:\n# dicom reader operator\n# Input: '/input' mapped directly to the input of the pipeline, which is populated by the DICOM Adaptor.\n# Output:'/output' for saving converted volume image in MHD format to file whose name\n# is the same as the DICOM series instance ID.\n- name: dicom-reader\n description: Converts DICOM instances into MHD, one file per DICOM series.\n container:\n image: clara/dicom-reader\n tag: 0.7.1-2008.1\n input:\n - path: /input\n output:\n - path: /output\n# lung-segmentation operator\n# Input: `/input` containing volume image data, MHD format, with a single volume.\n# Output: `/output` containing segmented volume image, MHD format.\n# `/publish` containing original and segmented volume images, MHD format,\n# along with rendering configuration file.\n- name: lung-segmentation\n description: Segmentation of lung using DL trained model.\n container:\n image: clara/ai-lung\n tag: latest\n requests:\n gpu: 1\n input:\n - from: dicom-reader\n path: /input\n output:\n - path: /output\n name: segmentation\n - path: /publish\n name: rendering\n services:\n - name: trtis\n # TensorRT Inference Server, required by this AI application.\n container:\n image: nvcr.io/nvidia/tensorrtserver\n tag: 19.08-py3\n command: [\"trtserver\", \"--model-store=$(NVIDIA_CLARA_SERVICE_DATA_PATH)/models\"]\n # services::connections defines how the TRTIS service is expected to\n # be accessed.

This section provides general guidelines on how to execute them on your local development machine. For information specific to a reference pipeline, please view the documentation of that pipeline.\n\n## Download the Reference Pipeline\n\nPlease refer to `Setup` section for downloading this Pipeline.\n\n## Run Reference Pipelines by Sending DICOM Instances Over Network\n\nMany reference pipelines are triggered by Clara DICOM Adaptor after it has received DICOM instances from external sender to one of its mapped AE Titles. This section explains the process with an example pipeline COVID-19 Pipeline. \n\n### External DICOM Sender and DICOM Receiver\n\nYou need an external DICOM Service Class User (SCU) application to send images to the Clara DICOM Adapter (acting as a DICOM SCP). Similarly, when your pipeline finishes executing, you may want to send the output to an external DICOM receiver.\n\nFor this example, we will use the open-source DICOM toolkit [DCMTK](https://dicom.offis.de/dcmtk.php.en) to provide the *external* DICOM sender and DICOM receiver functionality.\n\n#### Install DCMTK\n\nInstall DCMTK utilities by issuing the following command:\n\n```bash\nsudo apt-get install dcmtk\n```\n\n#### Setup an External DICOM Receiver\n\nYou can use the storescp utility as an external DICOM receiver. Open a terminal and run the following command to set up a DICOM Receiver. Create a directory in your machine where DICOM images produced by Clara Deploy SDK will be stored. We will refer to that directory as \"dicom-destination-directory\"\n\n```bash\nmkdir dicom-destination-directory\ncd dicom-destination-directory\nsudo storescp -v --fork -aet MYPACS 1004\n```\n\n`MYPACS` is the Application Entity (AE) title of the external DICOM Receiver.\n\n`1004` is the port number where `storescp` would be listening for any incoming DICOM traffic. Please note that the IP address will be the same as the local system.\n\n#### Setup an External DICOM Sender\n\nYou can use the storescu utility from DCMTK as a DICOM sender.\n\n### Customize the Pipeline\n\nBefore publishing a pipeline, default settings in the pipeline definition YAML file can be modified to configure the resource request and orchestration mode. We will use the `COVID-19-pipeline.yaml` to show the steps.\n\n#### Customize GPU request\n\nThe number of GPU's requested for an operator and/or a pipeline dependent service e.g. TensorRT Inference Server, can be customized if multiple GPU's are available.\n\nThe GPU request for TensorRT Inference Server is set at 1 by default shown below,\n```YAML\n- name: trtis\n # TensorRT Inference Server, required by this AI application.\n container:\n image: nvcr.io/nvidia/tensorrtserver\n tag: 19.08-py3\n command: [\"trtserver\", \"--model-store=$(NVIDIA_CLARA_SERVICE_DATA_PATH)/models\"]\n requests:\n gpu: 1\n\n```\nWith this setting, the TensorRT Inference Server can only access one GPU. When more GPU's are available and intended to be used to increase the inference performance, the GPU request number must be customized to match desired number, e.g. 4, as shown below,\n```YAML\n- name: trtis\n # TensorRT Inference Server, required by this AI application.\n container:\n image: nvcr.io/nvidia/tensorrtserver\n tag: 19.08-py3\n command: [\"trtserver\", \"--model-store=$(NVIDIA_CLARA_SERVICE_DATA_PATH)/models\"]\n requests:\n gpu: 4\n\n```\n**Note:** If another pipeline with a lesser number of GPU's for TensorRT Inference Server has been published and triggered, the changes made here will not affect the running instance of TensorRT Inference Server.\n\n#### Customize the Orchestration Mode\n\nIn this release of the Clara Deploy Platform, Clara Pipeline Driver [cpd] orchestration is supported, in addition to the Argo based orchestration mode.\n\nThis mode can be customized with the `api-version` attribute in the pipeline definition YAML file, setting the `api-version` to `0.3.0` makes the pipeline run in Argo mode, whereas setting this attribute to `0.4.0` Clara Pipeline Driver mode. The following example from the `COVID-19-pipeline.yaml` specifies Argo mode.\n```YAML\napi-version: 0.3.0\nname: COVID-19-pipeline\n```\n\n### Create the Pipeline\n\nPlease refer to `Setup` section to create this Pipeline.\n\n**Note:** Note down the pipeline ID as it would be used in a later section to define a new pipeline mapping in the DICOM adapter.\n\n### Configure the Clara DICOM Adapter\n\nWhen you send images to the Clara Deploy SDK, the DICOM Adapter component acts as the internal DICOM\nService Class Provider or a receiving agent.\n\nPlease refer to [Clara DICOM Adapter](https://docs.nvidia.com/clara/deploy/sdk/Services/DicomAdapter/public/docs/Setup.html) for setup instructions.\n\n### Trigger Pipeline\n\nA pipeline is triggered when a DICOM series is sent to the specific AE title of the Clara DICOM Adapter which is associated with that pipeline. To trigger this pipeline, you will need to have a set of relevant DICOM images that can be used as source input data.\n\nFor this pipeline, a sample test dataset in dicom format is available within the package in `/dcm`.\n\n* Open a terminal and go to the directory which contains all your DICOM images.\n\n* Trigger the pipeline (push DICOM data to the proper ae title)\n\n```bash\nstorescu -v +sd +r -xb -aet \"DCM4CHEE\" -aec \"COVID-19\" AA.BB.CC.DD 104 ./\n```\n\nReplace \"AA.BB.CC.DD\" with the IP of your local machine.\n\nWhen the above step is completed, you should see the following result in the terminal\n\n```bash\nI: Received Store Response (Success)
\nI: Releasing Association\n```\n\n### Check Job Status and Download/View Payloads in Clara Console/Dashboard\n\n**With Clara Orchestrator (API version >= 0.4.0)**\n\n* Go to the Clara Management Console using a web browser:\nThe URL is: `:32002`\n* Go to the `JOBS` view. You should see a job with a name that includes the name of the job you specified\n* You can inspect the status of each operator inside that job\n\nPlease check [Clara Management Console](https://docs.nvidia.com/clara/deploy/sdk/clara-ux/public/docs/README.html) to see the web application in detail.\n\n**With Argo Orchestrator (API version <= 0.3.0)**\n\nGo to the Clara dashboard UI using a web browser: The URL is `:8000`.\n\n* You should see a job with a name that includes the name of the pipeline you created.\n* You can inspect the status of each operator inside that job\n\n### Verify That the External DICOM Receiver Received Your Images\n\nIf your pipeline outputs DICOM images and sends them to an external DICOM receiver, you may want to verify that the images were indeed received. If you used the `storescp` utility from DCMTK as mentioned earlier, please use a terminal to navigate to the \"dicom-destination-directory\" and verify whether the expected images are stored there. Also, you may want to use a third-party DICOM\nviewer to view those images.","hasQuickStartGuide","advanced","","hasAdvanced","performance","hasPerformance","policies",[],{"_181":198,"_183":199,"_147":-5,"_155":26,"_157":26,"_170":197,"_158":66},{"_181":196,"_183":196,"_147":-5,"_155":26,"_157":26,"_170":197,"_158":66},{"_181":194,"_183":194,"_147":-5,"_155":26,"_157":26,"_170":195,"_158":66},{"_181":192,"_183":192,"_147":-5,"_155":26,"_157":26,"_170":193,"_158":66},{"_181":190,"_183":190,"_147":-5,"_155":26,"_157":26,"_170":191,"_158":66},{"_181":14,"_183":14,"_147":-5,"_155":26,"_157":26,"_170":189,"_158":66},{"_181":187,"_183":187,"_147":-5,"_155":26,"_157":26,"_170":188,"_158":66},{"_181":185,"_183":185,"_147":-5,"_155":26,"_157":26,"_170":186,"_158":66},{"_181":182,"_183":182,"_147":-5,"_155":26,"_157":26,"_170":184,"_158":66},"id","0.6.0-2005.1","name",[],"0.6.0-2006.3",[],"0.6.0-2006.4",[],[],"0.7.2-2010.1",[],"0.7.3-2011.5",[],"0.7.4-2103.2",[],"0.8.1-2108.1",[],"-","Latest (0.8.1-2108.1)","nvidia/clara/clara_ai_covid19_pipeline","key","nvidia/clara/resources/clara_ai_covid19_pipeline","resourceId","clara_ai_covid19_pipeline","shortDescription","Clara Deploy Clara Deploy AI COVID-19 Classification Pipeline","# Clara Deploy SDK is being consolidated into Clara Holoscan SDK\n\t\nMore info https://catalog.ngc.nvidia.com/orgs/nvidia/teams/clara/collections/claradeploy\n\t\n\n# Clara Deploy AI COVID-19 Classification Pipeline\n\nCAUTION: This is NOT for diagnostics use.\n\nThis asset requires the Clara Deploy SDK.
