There are more AWS SDK examples available in the AWS Doc SDK Examples GitHub repo.

HealthImaging examples using SDK for C++

The following code examples show you how to perform actions and implement common scenarios by using the AWS SDK for C++ with HealthImaging.

Actions are code excerpts from larger programs and must be run in context. While actions show you how to call individual service functions, you can see actions in context in their related scenarios.

Scenarios are code examples that show you how to accomplish specific tasks by calling multiple functions within a service or combined with other AWS services.

Each example includes a link to the complete source code, where you can find instructions on how to set up and run the code in context.

Get started

The following code examples show how to get started using HealthImaging.

SDK for C++

Scenarios

The following code example shows how to import DICOM files and download image frames in HealthImaging.

The implementation is structured as a workflow command-line application.

  • Set up resources for a DICOM import.

  • Import DICOM files into a data store.

  • Retrieve the image set IDs for the import job.

  • Retrieve the image frame IDs for the image sets.

  • Download, decode and verify the image frames.

  • Clean up resources.
