Creating a Segmentation App with MONAI Deploy App SDK¶
This tutorial shows how to create an organ segmentation application for a PyTorch model that has been trained with MONAI. Please note that this tutorial is based on the earlier version of the Spleen Segmentation Application.
Deploying AI models requires the integration with clinical imaging network, even if in a for-research-use setting. This means that the AI deploy application will need to support standards-based imaging protocols, and specifically for Radiological imaging, DICOM protocol.
Typically, DICOM network communication, either in DICOM TCP/IP network protocol or DICOMWeb, would be handled by DICOM devices or services, e.g. MONAI Deploy Informatics Gateway, so the deploy application itself would only need to use DICOM Part 10 files as input and save the AI result in DICOM Part10 file(s). For segmentation use cases, the DICOM instance file could be a DICOM Segmentation object or a DICOM RT Structure Set, and for classification, DICOM Structure Report and/or DICOM Encapsulated PDF.
During model training, input and label images are typically in non-DICOM volumetric image format, e.g., NIfTI and PNG, converted from a specific DICOM study series. Furthermore, the voxel spacings most likely have been re-sampled to be uniform for all images. When integrated with imaging networks and receiving DICOM instances from modalities and Picture Archiving and Communications System, PACS, an AI deploy application may have to deal with a whole DICOM study with multiple series, whose images’ spacing may not be the same as expected by the trained model. To address these cases consistently and efficiently, MONAI Deploy Application SDK provides classes, called operators, to parse DICOM studies, select specific series with application-defined rules, and convert the selected DICOM series into domain-specific image format along with meta-data representing the pertinent DICOM attributes.
In the following sections, we will demonstrate how to create a MONAI Deploy application package using the MONAI Deploy App SDK.
Note
For local testing, if there is a lack of DICOM Part 10 files, one can use open source programs, e.g. 3D Slicer, to convert NIfTI to DICOM files.
Creating Operators and connecting them in Application class¶
We will implement an application that consists of five Operators:
DICOMDataLoaderOperator:
Input(dicom_files): a folder path (
DataPath)Output(dicom_study_list): a list of DICOM studies in memory (List[
DICOMStudy])
DICOMSeriesSelectorOperator:
Input(dicom_study_list): a list of DICOM studies in memory (List[
DICOMStudy])Input(selection_rules): a selection rule (Dict)
Output(study_selected_series_list): a DICOM series object in memory (
StudySelectedSeries)
DICOMSeriesToVolumeOperator:
Input(study_selected_series_list): a DICOM series object in memory (
StudySelectedSeries)Output(image): an image object in memory (
Image)
SpleenSegOperator:
DICOMSegmentationWriterOperator:
Input(seg_image): a segmentation image object in memory (
Image)Input(study_selected_series_list): a DICOM series object in memory (
StudySelectedSeries)Output(dicom_seg_instance): a file path (
DataPath)
Note
The DICOMSegmentationWriterOperator needs both the segmentation image as well as the original DICOM series meta-data in order to use the patient demographics and the DICOM Study level attributes.
The workflow of the application would look like this.

from monai.deploy.operators.dicom_series_selector_operator import DICOMSeriesSelectorOperator
from monai.deploy.operators.dicom_series_to_volume_operator import DICOMSeriesToVolumeOperator
Creating Model Specific Inference Operator classes¶
Each Operator class inherits Operator class and input/output properties are specified by using @input/@output decorators.
Business logic would be implemented in the compute() method.
The App SDK provides a MonaiSegInferenceOperator class to perform segmentation prediction with a Torch Script model. For consistency, this class uses MONAI dictionary-based transforms, as Compose object, for pre and post transforms. The model-specific inference operator will then only need to create the pre and post transform Compose based on what has been used in the model training and validation. Note that for deploy application, ignite is not needed nor supported.
SpleenSegOperator¶
The SpleenSegOperator gets as input an in-memory Image object that has been converted from a DICOM CT series by the preceding DICOMSeriesToVolumeOperator, and as output in-memory segmentation Image object.
The pre_process function creates the pre-transforms Compose object. For LoadImage, a specialized InMemImageReader, derived from MONAI ImageReader, is used to convert the in-memory pixel data and return the numpy array as well as the meta-data. Also, the DICOM input pixel spacings are often not the same as expected by the model, so the Spacingd transform must be used to re-sample the image with the expected spacing.
The post_process function creates the post-transform Compose object. The SaveImageD transform class is used to save the segmentation mask as NIfTI image file, which is optional as the in-memory mask image will be passed down to the DICOM Segmentation writer for creating a DICOM Segmentation instance. The Invertd must also be used to revert the segmentation image’s orientation and spacing to be the same as the input.
When the MonaiSegInferenceOperator object is created, the ROI size is specified, as well as the transform Compose objects. Furthermore, the dataset image key names are set accordingly.
Loading of the model and performing the prediction are encapsulated in the MonaiSegInferenceOperator and other SDK classes. Once the inference is completed, the segmentation Image object is created and set to the output (op_output.set(value, label)), by the MonaiSegInferenceOperator.

Creating Application class¶
Our application class would look like below.
It defines App class, inheriting Application class.
The requirements (resource and package dependency) for the App can be specified by using @resource and @env decorators.
The base class method, compose, is overridden. Objects required for DICOM parsing, series selection (selecting the first series for the current release), pixel data conversion to volume image, and segmentation instance creation are created, so is the model-specific SpleenSegOperator. The execution pipeline, as a Directed Acyclic Graph, is created by connecting these objects through self.add_flow().

Executing app locally¶
We can execute the app in the Jupyter notebook. Note that the DICOM files of the CT Abdomen series must be present in the dcm and the Torch Script model at model.ts. Please use the actual path in your environment.

Once the application is verified inside Jupyter notebook, we can write the above Python code into Python files in an application folder.
The application folder structure would look like below:
my_app
├── __main__.py
├── app.py
└── spleen_seg_operator.py
Note
We can create a single application Python file (such as spleen_app.py) that includes the content of the files, instead of creating multiple files.
You will see such an example in MedNist Classifier Tutorial.

Packaging app¶
Let’s package the app with MONAI Application Packager.
!monai-deploy package -b nvcr.io/nvidia/pytorch:22.08-py3 my_app --tag my_app:latest -m model.ts
Building MONAI Application Package... Done
[2022-10-18 21:31:49,815] [INFO] (app_packager) - Successfully built my_app:latest
Note
Building a MONAI Application Package (Docker image) can take time. Use -l DEBUG option if you want to see the progress.
We can see that the Docker image is created.
!docker image ls | grep my_app
