Invisible Upgrades

Always up to date. No one notices.

Sirona RadOS ships new capabilities continuously — viewer, reporting, and AI upgrades — with no restart dialogs, installers, or version migrations. Each time the app opens, it picks up the newest build.

How Sirona is Different

PWA Architecture: Native feel, no installer

Sirona RadOS is a Progressive Web App that installs as a desktop application with its own icon and taskbar presence. To the user it feels like a native app — no browser tabs, no address bar. Under the hood it runs in Chrome: deploy it across your workstations with a managed browser policy, and updates need no packaging or push at all. Legacy approaches require dedicated workstations, manual installs, version lock-in, and downtime windows. With network-first caching, each launch picks up the latest version with no user interaction.

The architecture behind invisible upgrades

Continuous, silent upgrades aren't accidental. They require specific architectural choices at every layer — from how the app is delivered to how assets refresh.

Progressive Web App Deployment

Installs like a native app via Chrome enterprise policy or one-click install. Appears as a desktop application with its own icon, taskbar, and full-screen mode.

Network-First Caching Strategy

Checks for a fresh build on every load. The newest version is picked up on the next launch, with no user intervention and no restart dialogs.

WebGL Diagnostic Rendering

GPU-accelerated rendering delivers diagnostic-quality 2D/3D DICOM display entirely in the browser — no dedicated imaging software required.

On-Demand Frame Streaming

Prioritized frames are delivered on demand as you navigate the study, and studies are pre-cached from your worklist and hanging protocols, so the first image is up while the rest arrives.

Enterprise Deployment

Automated deployment through your existing device-management tooling. One policy sets the URL; every device installs and updates itself.

Global CDN Distribution

A global content delivery network keeps application assets close to every reader.

Invisible upgrades in practice

PWA Architecture

Installs as a desktop app. Updates invisibly.

Users click once, the app installs with a desktop icon, and it feels exactly like a native imaging application. Behind the scenes, every load checks for fresh assets. New versions deploy without restart prompts or version dialogs.

Install pushed by managed browser policy, or one click by the user

Own icon, taskbar presence, full-screen mode

Network-first caching detects updates automatically

No restart dialogs, no 'version 2.4 is required' messages

Continuous Deployment

New features ship continuously, silently.

Features roll out behind managed feature flags with staged release and instant rollback. Deployments land without downtime and without IT work. Version management becomes irrelevant when users always run the latest code.

Every change verified before release under a design-controlled SDLC

Managed feature flags enable staged rollouts and instant rollbacks

Deployments roll out without downtime

Viewer and reporting improvements ship continuously

Diagnostic Quality

Diagnostic rendering, in the browser.

GPU-accelerated browser rendering delivers diagnostic-quality display without a dedicated imaging workstation, and on-demand frame streaming keeps navigation responsive. No compromise between zero-footprint and image quality.

Everlight RadiologyRead the partnership announcement

“This partnership marks the beginning of the cloud-native era in radiology software globally. Sirona has delivered an architecture that is fundamentally different from anything else in the market today — Sirona is unified, and cloud-native from the ground up. For teleradiology, that architectural distinction is existential, not incremental.”
