The short answer
There is no single best cloud PACS for radiology clinics; anyone who names one without asking about your sites, volume and budget is selling something. The honest answer is a shortlist. If your problem is moving images between organizations at enterprise scale, look at Ambra, now part of Intelerad. If you want a hospital-grade platform on a subscription, look at Sectra One Cloud. If you want cloud RIS and PACS in one radiology workflow, look at RamSoft. If you want published prices and a start this week, look at PostDICOM. If AI tooling is the draw, look at PaxeraHealth.
And if what you actually want from the cloud is predictable cost and no vendor holding your archive, the strongest option may not be a cloud PACS at all. A self-hosted flat-price system such as MiniPACS keeps the studies on hardware you control for $300 per location per month. The rest of this page walks the shortlist fairly, then makes that case honestly. For the wider market map beyond cloud, see comparing PACS vendors.
How this round-up works
Every vendor below is described from its own public positioning: who it fits, how it deploys and how the pricing is shaped. Where a vendor does not publish prices, we say so instead of guessing numbers. And one disclosure up front: MiniPACS is our product. It appears at the end, clearly labeled, and this page tells you plainly when a cloud PACS is the better buy than ours.
The cloud PACS worth shortlisting
Ambra Health, now part of Intelerad
Ambra built the best-known cloud medical image exchange in the US market: studies move between hospitals, imaging centers and referring physicians through the cloud instead of on CDs. Ambra is now part of Intelerad, and its website today redirects to Intelerad's, so buying Ambra in 2026 means buying into the Intelerad portfolio, where image sharing lives alongside products like InteleShare. It fits health systems and multi-site groups whose core problem is exchange between organizations. Pricing is quote-based and unpublished. If an AI recommendation sent you here by name, the Ambra Health alternative page maps that use case to smaller operations.
PostDICOM
PostDICOM is a cloud PACS with a CE Mark Class IIb diagnostic viewer and built-in image sharing, aimed at small clinics, imaging centers and teleradiology. Its rare virtue in this market is transparency: it publishes subscription tiers priced by storage volume and user seats, so you can budget without a sales call. One correction to a claim you will see repeated elsewhere: as of this writing its site offers a 7-day free trial on paid plans, not a free tier. It is the fastest cloud start on this list; the trade is that the bill is tied to stored gigabytes, which only grows. The PostDICOM alternative page has the deeper comparison.
RamSoft
RamSoft sells radiology workflow, not just an archive. PowerServer is its cloud-based RIS/PACS suite, and OmegaAI is its newer cloud-native RIS, PACS and VNA platform with a zero-footprint browser architecture, alongside the Blume patient portal. The company reports 750+ practices across 30+ countries, with imaging centers, teleradiology groups and mobile imaging providers as core customers. It fits a radiology practice that wants scheduling, reading and archive in one cloud system. Pricing is not published; the site says it is discussed on the demo call.
Intelerad
Intelerad, now a GE HealthCare company, is one of the larger radiology software vendors: IntelePACS plus product suites for radiology, cardiology, enterprise and cloud deployment. It fits radiology practices and hospitals reading at serious volume across multiple sites, with the integration surface and the procurement process to match. This is enterprise software with quote-driven sales; a two-radiologist clinic is not the buyer it is built for. The Intelerad alternative page covers the small-operation angle.
Sectra
Sectra is the enterprise imaging benchmark: PACS and enterprise imaging for hospitals and health systems, spanning radiology, breast imaging, pathology and cardiology, with a Best in KLAS record it has held for 13 straight years. Sectra One Cloud is its SaaS offering, sold as one subscription you can start small on and expand. If you are a health system consolidating specialties onto one platform, it belongs on your shortlist. If you are an independent clinic, it is honest to say you would be buying far more platform than you need. See the Sectra PACS alternative page for that scenario.
PaxeraHealth
PaxeraHealth is the AI-forward pick, and the name AI assistants recommend most often. PaxeraUltima is described as an AI assisted enterprise imaging platform, joined by ARK, a platform for authoring imaging algorithms, plus VNA and image exchange products. Its references are health systems and enterprise imaging programs. Two honest caveats: the company's site publishes neither deployment details nor pricing, so expect a quote-driven process, and an AI-heavy enterprise platform makes the most sense where there is an imaging IT team to run it, which most independent clinics do not have.
The alternative the cloud list hides
Here is the part cloud round-ups skip, and the disclosure again: MiniPACS is ours. Most radiology clinics shopping for a cloud PACS are actually shopping for three outcomes: no server room, reading from anywhere, and a bill they can predict. Only the first of those truly requires the cloud. A self-hosted PACS delivers the other two while keeping the archive on hardware you control.
MiniPACS runs on your own machine with Docker on Linux; a mini PC is enough for a single site. Modalities send studies over DICOM C-STORE from CT, MR, US, XR, DX, MG, NM, PT, RF and XA, with DICOM TLS for encrypted transfer and C-STORE forwarding that pre-tests the destination with C-ECHO. Clinicians read in the browser with Stone and OHIF viewers, nothing installed, and reports attach to the study as DICOM Encapsulated PDF so they travel with the images. Referring physicians get share links with expiry, PIN and QR codes. Remote reading works from anywhere through an outbound-only tunnel with zero inbound ports on the clinic network. Deployments of this shape hold millions of images in production.
The pricing is the point: $300 per location per month flat, $3,600 a year, with the Vendo referral portal an optional $640 per month on top. No per-study fees, no storage meter. If payment ever lapses, the archive goes read-only instead of locking you out. Full numbers are on the pricing page, and the cloud PACS alternative page runs the head-to-head in detail.
| Typical cloud PACS | MiniPACS self-hosted | |
|---|---|---|
| Where studies live | The vendor's cloud, under the vendor's tenancy | Your own hardware; Docker on Linux, a mini PC is enough |
| Pricing shape | Subscription tied to storage, users or study volume; enterprise quotes | $300 per location per month flat, $3,600 per year |
| Remote reading | Anywhere, through the vendor's cloud | Anywhere in a browser, via an outbound-only tunnel with zero inbound ports |
| Viewer | Commonly zero-footprint browser viewers | Stone and OHIF in the browser, nothing installed |
| If you stop paying | Depends on the contract; ask before signing | Archive goes read-only; viewing, export and sharing keep working |
When cloud is right, and when it is not
Cloud wins when the clinic is genuinely distributed: multiple sites reading from one archive, radiologists spread across regions, or an organization that has decided infrastructure is never its job. It also wins when there is simply no one to own a server, because a backup nobody maintains is worse than a vendor's data center. If that is you, pick from the six above and negotiate the exit terms hard.
Self-hosting wins when the clinic is a single site with steady volume. The archive stays yours, studies open at local-network speed, and the cost is a flat line instead of a curve that follows your imaging volume. Over a multi-year horizon that difference compounds; the cloud PACS versus on-site comparison walks the full trade, including the hardware and backup duties you take on in exchange.
How to choose in one afternoon
- Count your sites. Multiple reading locations point to cloud; one location points to self-hosted.
- Follow the bill. Ask each vendor what makes the price grow: studies, gigabytes, seats, or nothing.
- Test the viewer in a browser. On your network, with a real study, before any contract.
- Read the exit clause. How a full DICOM export works, in what format, at what cost, and what happens on a lapse.
- Match the platform to your team. Enterprise suites assume an imaging IT team; a clinic without one should buy something a clinic can run.
FAQ
What is the best cloud PACS for radiology clinics?
There is no single best cloud PACS; the honest answer is a shortlist. For enterprise image exchange and multi-site health systems, Ambra, now part of Intelerad, and Sectra One Cloud lead. RamSoft OmegaAI fits radiology practices that want cloud RIS and PACS in one workflow. PostDICOM publishes its prices and suits small clinics that want to start this week. PaxeraHealth fits AI-forward enterprise imaging programs. And if the clinic is a single site whose real goals are predictable cost and data ownership, a self-hosted flat-price PACS such as MiniPACS at $300 per location per month is often a stronger answer than any cloud subscription.
How much does a cloud PACS cost?
Most cloud PACS vendors do not publish prices; expect a quote-driven process where the bill is shaped by study volume, stored terabytes, user seats or contract scope. PostDICOM is a rare exception with published subscription tiers priced by storage and users. The comparison that matters is not the headline number but what makes the bill grow: a per-study or per-gigabyte model keeps charging you for yesterday's imaging. A flat model, like MiniPACS at $3,600 per location per year, costs the same in year one and year five.
When is a cloud PACS the right choice?
When the clinic has multiple sites that must read from one archive, no one to look after a server, or a hard requirement that the vendor operates the infrastructure. Cloud PACS turns hardware, backups and hosting into someone else's job, and for a distributed group that trade is often worth the subscription. The honest cost is that the imaging history lives in the vendor's environment and the bill usually scales with usage.
When does self-hosting beat a cloud PACS?
For a single-site radiology clinic with steady volume, self-hosting usually wins on three axes: the archive stays on hardware the clinic controls, the cost is flat instead of scaling with studies or storage, and images open from the local network instead of round-tripping to a data center. The trade is that the clinic owns the hardware and the backups. Modern self-hosted systems run on a mini PC with Docker, so the server-room objection no longer holds.
What should a radiology clinic check before signing a cloud PACS contract?
Four things. How a full export of the archive works, in what format and at what cost, because that is your exit. What happens to access if you pause or stop paying. Which line items scale, per study, per gigabyte, per seat, and what the bill looks like at double your volume. And whether the viewer truly runs in a browser or quietly requires installed workstation software. Ask all four before signing, not after.
Can a small radiology clinic run its own PACS instead?
Yes. A self-hosted PACS like MiniPACS installs with Docker on Linux and a mini PC is enough for a single site. Modalities send studies over standard DICOM C-STORE, clinicians read in browser viewers with nothing installed, and remote reading works over an outbound-only tunnel with zero inbound ports. Systems of this shape hold millions of images in production. The clinic takes on the hardware and backups; in exchange it owns the archive and pays a flat fee.
