- Data protection with AWS's highly reliable infrastructure
- Unlimited storage capacity with automatic scaling
- Reduced operational burden through managed services

Target Healthcare Organizations
-------------------------------

- **Small to Medium Hospitals**: Want to implement PACS with minimal initial investment
- **Large Hospitals**: Considering cloud migration of existing systems
- **Radiology Clinics**: Need cost-effective image management solutions
- **Telemedicine Providers**: Require flexible cloud-based access
- **Healthcare IT Vendors**: Want to offer cloud PACS solutions to customers

Prerequisites
-------------

- AWS Account
- Appropriate IAM permissions
- VPC (existing or new)
- NAT Gateway (for ECR access from private subnets)

Supported Regions
-----------------

This solution is designed for deployment in **us-east-1 (N. Virginia)** via AWS Marketplace.

.. note::
   While AWS HealthImaging is available in multiple regions (us-west-2, eu-west-1, ap-southeast-2),
   this AWS Marketplace solution currently supports us-east-1 only due to container image hosting limitations.
