Unomed Cloud PACS

Swiss cloud PACS and vendor-neutral archive for storing, viewing and sharing DICOM medical images in the browser, integrated with existing medical practice workflows.

Unomed Cloud PACS is a Swiss-operated cloud picture archiving and communication system (PACS) and vendor-neutral archive for medical practices and clinics. It is built by Unomed AG in Zurich for teams that want DICOM studies archived, viewed in the browser, and shared with referrers or patients without running an on-site PACS server.

The product sits beside the practice information system you already use. Modalities and partner institutes can send studies in; Unomed matches them to patients, stores them in its Swiss-hosted archive (per the vendor), and opens them from the patient record or a zero-footprint browser viewer.

The concrete differentiator for Swiss practices is the combination of a Zurich legal entity, claimed Swiss image hosting under the Swiss Federal Act on Data Protection, and workflow overlays (inbox matching, messenger sharing, Radiology Bridge) aimed at keeping existing PIS and PACS investments in place.

Swiss-operatedCloud PACS / VNADICOM archiveBrowser viewerPIS overlay

Shortlist for Swiss practices that want a cloud DICOM archive, browser viewing and referrer sharing without replacing their PIS, and that accept a Zurich SaaS vendor with claimed Swiss image hosting. Skip when you need a default CE-marked diagnostic viewer, a fully public subprocessor and audit pack, or a self-hosted PACS you operate yourself. Consider PostDICOM or a classic on-prem PACS plus sharing tool when those constraints dominate.

Key capabilities

Central archive for studies from in-house modalities and external institutes, with DICOM export so you can take the archive with you. Storage is billed as you grow; long-term statutory retention remains the customer's duty under Unomed's terms.

Open studies in the browser with nothing installed on the workstation. OHIF is the default; other viewers can be connected on request. Unomed's GTCs state the standard viewer is not authorised for diagnostic reporting.

Inbound studies land in an inbox; Unomed suggests the matching patient (including fuzzy name matches) and a human confirms. Useful when institutes send studies that do not already carry a clean order from your record.

Send studies to colleagues, referrers and patients through Unomed messenger. Recipients without an account get a time-limited guest link; registered users keep the thread in case chat instead of CDs or ad-hoc portals.

Connect DICOM modalities like a second destination printer, autoroute from an existing institute PACS via Radiology Bridge, or integrate via DICOMweb/Medical API. Keeps on-site PACS investments when you only need outbound routing to Unomed practices.

Opens studies from the patient record in supported web-based Swiss practice systems without replacing the PIS. Vendor lists 16+ systems with several official partners; desktop-only software needs a feasibility discussion.

Best fit when

  • Swiss medical or dental practices that want cloud DICOM archive and sharing without an on-site PACS project
  • Teams that must open imaging from an existing web-based practice system rather than a second patient search
  • Institutes that need to autoroute studies to referring practices while keeping an existing PACS (Radiology Bridge)
  • Buyers who prioritise a Swiss contracting entity and vendor-claimed Swiss image residency under the FADP
  • Workflows that share studies with referrers or patients via links instead of CDs or one-off portals

Poor fit when

  • Organisations that require the included viewer to be a certified diagnostic/reporting workstation out of the box
  • Buyers that need a published named subprocessor list and independent ISO/SOC evidence before first sales call
  • Teams seeking a fully self-hosted open-source PACS they operate themselves
  • Hospitals needing a full RIS/PACS suite beyond practice-oriented cloud archive and sharing

Consider instead when

  • When: You need a European cloud PACS peer outside Switzerland or broader multi-country packaging

    Consider: PostDICOM (Netherlands) or other EU cloud PACS vendors

    Feature parity is not claimed; compare residency contracts and viewer certification directly.

  • When: You primarily need raw cloud object storage or hospital-grade imaging services on a hyperscaler

    Consider: AWS or Azure health/imaging stacks with your own viewer and compliance design

    More infrastructure flexibility; you own more of the clinical workflow glue.

  • When: You must keep all image data on premises under your sole operational control

    Consider: Classic on-prem PACS plus a dedicated sharing portal

    Unomed is cloud SaaS with a local connector, not a self-hosted Unomed server product.

Considerations & known limitations

  • MediumUS-group cloud components in the data path

    Even with Swiss HQ and claimed Swiss image hosting, AWS and Firebase endpoints appear in public privacy/CSP materials. Procurement should obtain the named subprocessor annex and assess CLOUD Act residual risk.

  • HighDefault viewer not for diagnosis

    If radiologists must report from the included viewer, Unomed alone is the wrong shortlist item unless a certified diagnostic viewer is contracted.

  • MediumNo public ISO/SOC or independent audit

    Assurance currently rests on vendor policies, Swiss entity status and contractual ABV rather than published certificates.

  • MediumSubprocessor list not published

    Privacy policy says processors can be requested at any time but does not name hosting vendors on the page. Blockers for security questionnaires until the annex is shared.

Open questions for due diligence

  • Will Unomed provide the current named subprocessor list (hosting, backup, email, SMS, identity) under NDA or in the ABV annex?
  • Which exact Swiss data-centre operators and certifications cover the DICOM archive?
  • Is a CE-marked / certified diagnostic viewer required for your reporting workflow, and which third-party option will Unomed integrate?
  • What SLA, backup/RPO and export support apply to your Cloud PACS tier?

Frequently Asked Questions

No. Unomed's general terms state that the platform and the standard included DICOM viewer (for example OHIF) are not intended or authorised for diagnosis. If you need certified reporting, Unomed may resell or integrate a third-party diagnostic viewer where the third-party manufacturer remains responsible for conformity.

Unomed claims image storage and primary hosting in Swiss data centres under the Swiss FADP. The privacy policy also lists identity/liveness processing in the EU (Ireland) and speech recognition in the EU (Denmark). A named public subprocessor list is not published (available on request). Technical headers on the API reference AWS S3 in the Zurich region and AWS Rekognition endpoints in Ireland, and the app uses Firebase for push notifications. Ask for the current ABV annex before procurement.

Yes for many institute workflows. Radiology Bridge connects an existing PACS so studies can be autorouted into Unomed archives used by referring practices, rather than forcing a rip-and-replace. Practices can also attach modalities directly through the cloud connector.

Cloud PACS is a paid subscription module with usage-related options such as Radiology Bridge. Unomed markets monthly cancellation for core packages and offers demos; Connect messenger sharing is described as permanently free. Exact package limits belong on the official pricing pages because they change.

Yes in the Swiss B2B model described in the GTCs: when Unomed processes patient data for a healthcare provider it acts as processor under an Auftragsbearbeitungsvertrag (ABV) that the terms treat as part of the contract. Confirm the signed ABV, TOMs and subprocessor annex for your organisation.
