Medical imaging generates large volumes of complex healthcare data. Storing, accessing, and processing this data efficiently can become challenging when imaging systems depend on traditional infrastructure.
AWS HealthImaging is an AWS service designed to help healthcare organizations store, transform, and access medical imaging data at scale.
For developers, HealthImaging provides APIs and cloud-based capabilities that can support imaging applications, diagnostic workflows, healthcare data platforms, and medical imaging viewers.
This guide explains how AWS HealthImaging works, its architecture, APIs, integrations, security considerations, and practical development use cases.
What Is AWS HealthImaging?
AWS HealthImaging is a cloud service for storing, transforming, and accessing medical imaging data.
It is designed for healthcare imaging workloads and supports medical imaging standards such as DICOM.
Instead of managing traditional imaging storage infrastructure, development teams can use AWS-managed capabilities to build applications around medical images.
A typical workflow can look like:
Medical Imaging System → HealthImaging → APIs → Healthcare Application
This architecture allows developers to build applications without managing every aspect of the underlying imaging storage infrastructure.
Why Developers Should Consider AWS HealthImaging
Medical imaging applications often need to handle large datasets while providing fast access to authorized users.
Traditional architectures can require significant infrastructure for:
Image storage
Data retrieval
Metadata management
Scaling
Backup
Infrastructure maintenance
AWS HealthImaging provides managed cloud capabilities that can reduce some of this infrastructure burden.
Developers can focus more on application functionality while using AWS services for the underlying imaging data layer.
Understanding DICOM in HealthImaging
Digital Imaging and Communications in Medicine (DICOM) is widely used for medical imaging information and related workflows.
Medical imaging systems can generate DICOM data from modalities such as:
MRI
CT
X-ray
Ultrasound
Mammography
Nuclear medicine
Working with medical imaging requires handling both image data and associated metadata.
AWS HealthImaging is designed around medical imaging workflows and provides capabilities for working with DICOM-compatible imaging data.
AWS HealthImaging Architecture
A HealthImaging-based application can contain several components.
A simplified architecture may look like:
Medical Imaging Device
↓
DICOM Data
↓
AWS HealthImaging
↓
HealthImaging APIs
↓
Backend Application
↓
Web / Mobile Imaging Viewer
Additional AWS services can be introduced depending on the application.
For example:
HealthImaging
↓
API Layer
↓
Application Backend
↓
Authentication
↓
Imaging Viewer
The architecture should be designed according to the application's security, performance, integration, and clinical workflow requirements.
Working With AWS HealthImaging APIs
Developers interact with HealthImaging through AWS APIs.
These APIs can support operations related to imaging data stores, image sets, metadata, and image retrieval.
A typical application might use APIs to:
Identify an imaging data store.
Import medical imaging data.
Retrieve image metadata.
Access image frames.
Display images through an application.
Connect imaging information with other healthcare data.
API-based access makes HealthImaging suitable for applications that need programmatic access to medical imaging data.
Importing Medical Imaging Data
A healthcare organization may already have medical images stored in PACS or other imaging systems.
Moving this data into AWS requires an appropriate ingestion architecture.
A possible workflow is:
PACS / Imaging System
↓
Data Transfer
↓
AWS HealthImaging
↓
Image Sets
↓
Application APIs
The implementation depends on the existing PACS environment, DICOM workflows, network architecture, and data migration requirements.
Developers should also consider how existing metadata and identifiers will be handled during migration.
Image Sets and Metadata
One important concept when working with AWS HealthImaging is the image set.
An image set represents a collection of medical imaging data that can be managed and accessed through HealthImaging.
Metadata is also important because imaging applications need more than raw image pixels.
Applications may use metadata to identify information associated with:
Patients
Studies
Series
Imaging instances
Acquisition information
Developers should design their data model carefully when connecting HealthImaging with other healthcare applications.
Building a Medical Imaging Viewer
At Oodles, our practical use case for AWS HealthImaging is building a web-based medical imaging application.
A simplified architecture could include:
AWS HealthImaging
↓
API Layer
↓
Backend Service
↓
Web Imaging Viewer
The viewer can provide functionality such as:
Image navigation
Zooming
Panning
Window and level controls
Study navigation
Series selection
Metadata display
The exact viewer capabilities depend on the application's clinical and technical requirements.
A developer should also consider browser performance because medical imaging datasets can be significantly larger than conventional application images.
Integrating HealthImaging With Healthcare Applications
Medical imaging is often only one part of a larger healthcare workflow.
An imaging application may need to connect with:
EHR systems
EMR systems
Patient portals
Radiology information systems
PACS
Laboratory systems
Healthcare APIs
FHIR can be useful when connecting imaging-related information with broader healthcare workflows.
For example:
EHR → FHIR API → Imaging Application → HealthImaging
This can help developers build applications that connect clinical information with medical imaging workflows.
AWS HealthImaging and Healthcare Data Integration
Healthcare organizations often have multiple sources of information.
Medical imaging may exist separately from patient demographics, encounters, observations, and clinical documentation.
Integration architecture can connect these systems.
For example:
EHR
↓
FHIR / Healthcare API
↓
Application Backend
↓
AWS HealthImaging
↓
Imaging Viewer
This allows developers to build applications that provide a more connected experience.
However, integration requires careful handling of patient identifiers, authorization, metadata mapping, and data consistency.
Security Considerations
Medical imaging can contain sensitive patient information.
Security therefore needs to be considered across the complete architecture.
Important areas include:
Identity management
Authentication
Authorization
Encryption
Network security
API access controls
Audit logging
Data access monitoring
AWS Identity and Access Management (IAM) can be used to control access to AWS resources.
Application-level authorization should also be designed carefully.
For example, a radiologist may need access to specific imaging studies, while a patient may have access to only their own authorized information.
Security requirements should be aligned with the applicable healthcare regulations and organizational policies.
Scaling Medical Imaging Workloads
Medical imaging environments can generate large amounts of data.
A healthcare organization may have thousands or millions of imaging studies accumulated over time.
Cloud infrastructure can provide a scalable foundation for these workloads.
Developers should consider:
Data ingestion volume
API request volume
Viewer performance
Concurrent users
Data retrieval patterns
Network bandwidth
Application caching
The architecture should be tested with realistic imaging workloads rather than ordinary application data sizes.
AWS HealthImaging and AI Workflows
Medical imaging is also becoming increasingly connected with artificial intelligence.
AI systems can process imaging data for use cases such as:
Image classification
Detection assistance
Segmentation
Image analysis
Research
Workflow prioritization
A potential architecture could look like:
Medical Images
↓
AWS HealthImaging
↓
Image Retrieval
↓
AI / ML Processing
↓
Analysis Results
↓
Healthcare Application
AI output should be treated according to its intended clinical use and appropriate validation requirements.
Developers should also consider data governance, model performance, security, and clinical oversight.
Common AWS HealthImaging Development Challenges
Large Imaging Files
Medical images can be significantly larger than normal application assets.
Applications therefore need efficient retrieval and rendering strategies.
Legacy PACS Integration
Existing healthcare organizations may rely heavily on established PACS infrastructure.
Migration and integration need to account for existing workflows.
Healthcare Interoperability
Imaging applications may need to connect with EHRs, FHIR APIs, DICOM systems, and other healthcare platforms.
Security
Patient information requires appropriate access controls, encryption, monitoring, and governance.
Viewer Performance
A technically correct backend does not guarantee a good imaging experience.
Developers need to optimize image loading, rendering, navigation, and browser performance.
