Zero-Footprint

Nothing to install. Nothing to upgrade. Just read.

Sirona Workspace is a Progressive Web App — it installs like a native app with its own icon and feels native, yet runs entirely in the browser. New features ship invisibly. No version management. No interruptions.

How Sirona is Different

PWA architecture. Native feel, zero install.

Sirona Workspace installs as a desktop app with its own icon and taskbar presence — indistinguishable from a native application. Deploy across your workstations via Chrome enterprise policies or Active Directory. Network-first caching means the latest version loads automatically.

The architecture behind zero-footprint

A zero-footprint experience isn't accidental. It requires specific architectural choices at every layer.

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 fresh assets on every load. The latest version is available immediately — no user intervention, no restart dialogs.

WebGL Diagnostic Rendering

VTK.js with WebGL hardware acceleration delivers diagnostic-quality 2D/3D DICOM rendering entirely in the browser — no desktop app required.

PixelWSS Streaming Layer

WebSocket-based pixel streaming delivers prioritized frames on-demand. Adaptive bitrate keeps diagnostic quality from fiber to cellular.

Enterprise Deployment (AD/PDQ)

Automated deployment via Active Directory or PDQ Deploy. One policy sets the URL; every device auto-installs and auto-updates.

CloudFront CDN + S3 Distribution

Global content delivery ensures diagnostic-quality assets load instantly from any geographic location.

Built for how radiologists actually work

PWA Architecture

Installs as a desktop app. Updates invisibly.

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

One-click install via WebAppInstallForceList

Own icon, taskbar presence, full-screen mode

Network-first caching detects updates automatically

No restart dialogs or version-required messages

Continuous Deployment

New features ship continuously, silently.

Features flow through GitHub Flow, Harness.io feature flags, and A/B testing gates. Radiologists never know a deployment happened. Version management becomes irrelevant when users always run the latest code.

GitHub Flow: main branch is production-ready

Harness.io feature flags for safe rollouts and rollbacks

Blue-green deployments behind CloudFront

Continuous cadence — viewer and reporter improvements constantly

Diagnostic Quality

Browser rendering matches dedicated hardware.

VTK.js with WebGL hardware acceleration delivers the same diagnostic performance as expensive imaging workstations. PixelWSS keeps frames responsive on any network. No compromise between zero-footprint and image quality.

PixelWSS: on-demand WebSocket frame streaming

Global CDN delivery keeps assets fast from any location

Adaptive bitrate for fiber, broadband, cellular, or Starlink

IT Liberation

Eliminate workstation management entirely

No hardware procurement. No OS patching. No version lock-in. No spare inventory. Practices that adopt Sirona have generally reduced imaging IT overhead by more than 75% — every device with a modern Chrome browser becomes their workstation fleet.

No dedicated imaging workstations to buy or refresh

No OS patching or PACS software installs

No version lock-in or coordinated upgrade windows

Imaging IT overhead all but eliminated after adoption

Any browser

every device with modern Chrome is a diagnostic reading station

Who We Are to Our Customers

“The experience of working with Sirona has been phenomenal. You guys are easily the most responsive team that I've worked with in regards to IT. When I say there's an issue, you guys are on it right away. That has been just amazing. Every other place should look at Sirona as an example.”

Launch Day Excerpt: How Sirona is Built Different

Sirona's RadOS platform understands how a radiology practice really works. It starts by unifying all the data and tools needed for physicians to read seamlessly from anywhere at any time. The unique architecture and AI capabilities can automate many of the clicks, drags, scrolls, and “scratch thats” slowing your radiologists down.

FAQs

What exactly is a Progressive Web App (PWA)?

A PWA is a web application that installs as a desktop app — with a desktop icon and taskbar presence — but runs entirely in the browser. Sirona Workspace installs once, feels like a native application with its own window, and updates automatically from the server. You deploy once; updates happen silently.

How do updates happen without interrupting reading?

Sirona uses network-first caching: every time the app loads, it checks the server for new assets. If newer assets exist, they're cached for the next restart. Users never see a 'restart required' dialog — they simply work, and the next time they load the app, they get the latest version. Features roll out safely via Harness.io feature flags with instant rollback.

Does zero-footprint mean compromised image quality?

No. Sirona's diagnostic viewer uses VTK.js with WebGL hardware acceleration — full DICOM 2D/3D rendering at diagnostic quality. PixelWSS streaming delivers prioritized frames on-demand with adaptive bitrate from fiber to cellular. Same diagnostic performance as dedicated imaging workstations, delivered entirely through the browser.

How do we deploy this across our entire enterprise?

Chrome enterprise policy (WebAppInstallForceList) pushes the app URL to all managed devices. Active Directory or PDQ Deploy can automate setup. Every workstation then receives updates automatically — no IT involvement after the initial policy push.

What if a radiologist wants to work from home or on a personal device?

They visit the Sirona login page in any modern Chrome browser, click 'Install,' and the app appears on their home screen or desktop. It works on a laptop, iPad, or any device with Chrome. No VPN, no special software, no infrastructure setup.

Does the browser need to be running for the app to work?

The app runs on the browser engine, but it feels like a native application — it has its own window, window controls, and taskbar presence. Radiologists interact with the app window, not a browser tab. Closing the window closes the app; reopening launches fresh from the latest cached assets.
