PACS Archive Modernization
Modernize your archive. Without the burden.
Legacy archives are expensive, on-prem, and brittle, refreshed every five years and priced per appliance. Sirona's cloud-native archive is secure and elastic. Nothing to provision. Pay per study, not per rack.
How Sirona is Different
Your archive, without the rack
Legacy PACS archive is a depreciation schedule disguised as software. Every five to seven years, the appliances need replacing. Capacity has to be forecast a quarter ahead, then over-provisioned to be safe. Sirona runs on cloud-native object storage with intelligent tiering — capacity is elastic by definition. There is no rack to refresh, no quote to negotiate, no end-of-life to plan around. The archive scales when your study volume grows; storage tiers automatically as studies cool. Your IT team manages access policies, not hardware.
Everything an archive should be in 2026
Sirona's archive is cloud-native by design — not a port, not a hybrid, not a managed appliance. Every capability below ships standard.
Cloud storage included
Backed by AWS S3 with intelligent tiering. Capacity is elastic — no forecasting, no over-provisioning, no overages. Tiering between hot and cold storage is automatic and invisible to your team.
Explore ArchiveDICOMweb-native
Standards-based ingest and retrieval. No proprietary formats, no vendor lock-in. Any DICOM-compliant system can read from or write to your archive.
Explore InteroperabilityPriors ready before you open
Worklist-driven prefetch and on-demand frame rendering. Priors are warmed before the study opens, including ones that have tiered down to cold storage.
Explore StreamingHIPAA-grade security
Encryption at rest and in transit, role-based access control, and audit logging — backed by an active SOC 2 Type II program and HIPAA controls.
Explore SecurityAutomated DICOM normalization
Tags are validated and normalized on ingest. No pre-migration scrubbing. No data-quality projects. Inconsistent legacy headers are cleaned automatically as studies stream in.
Explore MigrationUnified by default
Your archive shares one data model with the viewer, reporter, and worklist. No middleware, no sync jobs — every study, prior, and report accessible from one platform.

Four reasons modernizing your archive on Sirona is lower-risk than the path your incumbent is selling.
Migration
Migrate at your pace, not your vendor's
Sirona's overlay-first model removes cutover risk. Standard DICOMweb integrations route new studies to both systems while historical priors stream over in the background. Parallel-run validation confirms every study before you flip routing. Radiologists never stop reading.

Economics
Trade CapEx for clarity
Cloud-native economics replace the lumpy, front-loaded cost of legacy archive. No upfront infrastructure. No five-year refresh. No capacity overages. One predictable per-study subscription, with storage tiering handled inside the platform.
$0 upfront infrastructure — no CapEx to start
Per-study pricing — costs scale with volume, not vendors
Hot and cold storage tiering handled by Sirona — nothing to forecast or manage
No refresh cycles, no licensing true-ups, no surprise CapEx
Performance
Cold storage shouldn't feel cold
A modern archive should never make radiologists wait. Worklist-driven prefetch loads priors before the study opens, so the archive tier a study lives in is not something the radiologist feels.

Worklist-driven prefetch loads priors before they're needed
On-demand frame rendering — multi-frame studies stream losslessly
Priors pre-loaded from the worklist, across hot and cold tiers
Resilience
Built to outlive your data center
Patient images need to survive longer than any single appliance, data center, or vendor. Sirona's archive runs on durable AWS S3 storage with HIPAA-compliant encryption, audit logging, and DICOMweb portability — so your data is protected, auditable, and never trapped.
AWS S3 durability (11 nines) with multi-AZ high availability
Encryption at rest (AES-256) and in transit (TLS 1.2+)
Audit logging — changes to clinical information traced and retained
DICOMweb portability — your data is yours, in a standard format

Practices that moved fast on Sirona
Built Different: the architecture behind RadOS
Sirona's technical advisor Jeff Queisser (Co-Founder of Box, NYSE: BOX) on how RadOS was architected for reliability and performance at scale.

“We were live on Sirona in four weeks. As any growing practice will understand, that speed wasn't a convenience — it was the business plan. There is no other radiology platform where that timeline could even have been a consideration.”
