PACS Archive

Cloud archiving without
servers or tradeoffs

Radiology’s first completely cloud-native PACS archive delivers faster access, higher reliability, state-of-the-art security, and industry-leading cost savings. To do the same, others have to rebuild — from scratch.

Your PACS archive was designed before Netscape.

As a result, your most important database is incompatible with the cloud, and unsecure over the internet.

This makes data management and migration 10x more expensive.

How Sirona is Different

Cloud Native Storage

RadOS was built from first-principles leveraging the most cutting-edge cloud-native infrastructure and security tooling, making Sirona the first fully cloud-native PACS Archive in the market.

a fully managed archive solution

Never manage servers or integrations ever again

Sirona couples cloud-native infrastructure with fully managed integration services so practices can fully offload the operational burden of archiving.

Integration

Protect your data & offload security questionnaires

HIPAA & SOC2 compliant, Sirona couples state-of-the-art security tooling with managed integration services so private practices can win new business and make security questionnaires our problem.

Flexible role-based access control

Robust technologist workflows

Everything your rad techs need to support your radiologists.

Elastic Auto-Scaling

Scale your practice and your archive on demand

Sirona stores all of your data in a fully elastic cloud-native environment, allowing you to scale your practice from 10,000 to 10,000,000 exams per year on-demand.

From one user to thousands

RadOS’ microservices driven architecture uses Kubernetes to scale up and down on demand.

From gigabytes to petabytes

Sirona designed RadOS to power radiology world-wide. The result: we can store as much data as you can send us.

From one DICOM feed to hundreds

Sirona can ingest as much data from as many sources as your practice requires.

Enterprise Grade

Move all your data to the cloud with Sirona

The Sirona team has managed PACS implementations at the world's largest and most complex healthcare institutions over the course of their careers — including the single largest PACS rollout in history (a nation-wide rollout in Ireland).

Data Migration

Move petabytes of data easier

From one PACS or fifty, Sirona's software was built by a services team that's seen it all before. Together, our people and our technology make data migration easier than ever.

Reimagining Archiving (Coming Soon)

Evolving PACS value beyond archiving

While Sirona’s archive was built (first and foremost) to power the viewer, reporter, and worklist applications that our customers love, the value of Sirona as a standalone archive will evolve as we ship new software and services over 2026.

Research with RadOS SDK

By ingesting both DICOM & HL7 natively, our RadOS SDK will allow IT teams and researchers alike to develop and deploy custom software that leverages all the data and all the applications layer software that power radiology practice. This will make Sirona's archive a production and research PACS all in one, and elevate the value IT teams can deliver to their practices.

Fully Managed IT

For smaller practices that wish to outsource their IT function completely, Sirona is developing a managed service for an additional per-case fee that we expect to make available in 2026.

FAQs

Can I buy Sirona as a standalone-archive?

Yes, through our Sirona Core offering. Most archiving-only customers exceed Sirona Core’s minimum fee, so please contact a Sirona sales representative to get a formal quote (click “See Sirona” in the top right of your screen).

Can I use Sirona’s archive for business continuity purposes?

Yes, through our Sirona Core offering. Most business continuity customers exceed Sirona Core’s minimum fee, so please contact a Sirona sales representative to get a formal quote (click “See Sirona” in the top right of your screen).

How long and how expensive is it to migrate 1pb of data?

We’ve completed 1pb migrations in as little as one month, and for anywhere from $0.01–0.15 per exam. The speed and cost of data migration vary meaningfully based on what archive is being replaced, and the nature of your practice model.
