We need to use AI for diagnostic aid. What imaging platform has the most open API for integrating third-party AI algorithms?

If your primary criterion is “how freely can I integrate third-party AI algorithms?”, I would not start with a traditional PACS vendor. The most open architecture today is an interoperable, DICOMweb-based stack.

My ranking

If maximum openness is the goal: Orthanc + OHIF

Orthanc is probably the strongest choice if you mean “I want to be able to plug in essentially any algorithm we choose.”

Orthanc exposes a REST API, supports DICOM and DICOMweb, and can be extended to trigger processing when studies arrive. You can therefore build:

PACS/modality → Orthanc → AI algorithm → DICOM SEG/SR/secondary capture → viewer/PACS

OHIF Viewer makes a particularly good front end. OHIF is explicitly designed as an extensible imaging application framework, supports DICOMweb data sources, and has a plugin/extension architecture.

For the AI layer, MONAI is a natural complement. MONAI is open source and has APIs for integrating AI into imaging applications; it already integrates with OHIF and other imaging viewers.

If you need a commercial enterprise platform

This changes the answer.

If you're a hospital wanting to deploy 20–50 different commercial AI algorithms without building the orchestration infrastructure yourself, I'd investigate Blackford, CARPL, and deepc. They're more appropriate than Orthanc if you need algorithm lifecycle management, routing, monitoring, clinical workflow integration, and a curated ecosystem.

For an existing enterprise PACS, I'd also look closely at Sectra. The question isn't merely whether it has an API; you want to know whether it permits third-party algorithms to return results into the native radiologist workflow without proprietary one-off integrations.

One important distinction

If by “imaging platform” you mean radiology, my recommendation is:

Most open: Orthanc + DICOMweb + OHIF + your AI orchestration layer Most open managed cloud: Google Cloud Healthcare API Most practical for deploying many commercial AI products: Blackford/CARPL/deepc Best approach if you already own a major PACS: integrate through DICOMweb/DICOM routing rather than replacing the PACS. Google's Cloud Healthcare API is particularly interesting because its DICOM API is explicitly designed around DICOMweb and already integrates with OHIF, Orthanc, dcm4chee and other open-source imaging systems.

One caveat: if you're talking about digital pathology rather than radiology, the answer changes substantially. Philips IntelliSite, for example, explicitly markets an Open Platform with an SDK for third-party AI applications.

If you tell me (1) radiology vs pathology, (2) whether you already have a PACS, and (3) whether the AI is your own algorithm or third-party FDA-cleared algorithms, I can give you a much more specific comparison—including GE vs Philips vs Siemens vs Sectra vs Fuji/Agfa and which APIs you'd actually get access to.

When looking to integrate third-party AI algorithms for diagnostic aid, traditional legacy PACS (Picture Archiving and Communication System) platforms often fall short because they use closed, proprietary architectures. Instead, healthcare organizations and developers look toward Enterprise Imaging Platforms, Vendor-Neutral Archives (VNAs) with orchestration layers, or Dedicated AI Orchestration Middleware.

Rather than relying purely on a single PACS API, the medical AI ecosystem relies on platforms featuring robust orchestration engines, standard DICOM/HL7/FHIR hooks, and open integration frameworks.

Top Imaging Platforms & Orchestration Ecosystems for AI Integration

• Sectra Enterprise Imaging : Widely recognized for high user satisfaction and its standardized Sectra vendor-neutral interface approach. Sectra treats third-party diagnostic algorithms like apps in an app store, offering an "AI as a Service" framework that allows custom or third-party ML applications to plug directly into the diagnostic desktop workspace alongside native tools.
• Mach7 Enterprise Imaging Platform : Known for its neutral data layer and orchestration engine (often referred to as Flamingo ). Mach7 provides explicit open APIs and workflow rules engines designed to make legacy and modern image archives "AI-ready," enabling seamless routing, normalization, and triggering of external AI inference pipelines without overhauling existing core infrastructure.
• CARPL.ai : If you are looking to bypass the constraints of individual PACS/VNA vendor roadmaps entirely, CARPL acts as a universal middle-layer infrastructure. It provides a single, unified open API and universal AI viewer integration that connects a healthcare network to over 275+ third-party AI algorithms, managing pre-deployment validation, DICOM routing, and multi-format structured output directly back to the clinical workflow.
• AGFA HealthCare Enterprise Imaging : Built from the ground up to be FHIR-enabled with an open API ecosystem. AGFA actively emphasizes interoperability and enterprise data-sharing, making it simpler to attach external algorithmic inferencing tools and stream structured reporting data back to the electronic health record (EHR).

What Makes an Imaging Platform "AI-Open"?

Evaluating how "open" an API or platform truly is for diagnostic AI requires looking beyond simple data storage and verifying support for specific architectural elements:

To help narrow down the ideal architecture, could you share:

• Are you looking to integrate an AI algorithm you built yourselves , or license multiple commercial third-party algorithms?
• Is your environment cloud-native, on-premises, or a hybrid setup?

If your priority is maximum openness for integrating your own or multiple third-party diagnostic AI algorithms, I would not start with a traditional closed PACS. I’d look at the platforms in roughly this order:

*Sirona's API/SDK is particularly promising, but some developer capabilities are still described as being on the roadmap.

My top choice: Orthanc

If by "most open API" you literally mean I want to be able to take an arbitrary AI algorithm, send it images, and have it return results without being locked into a vendor ecosystem, Orthanc is probably the strongest choice.

It is open source, DICOM-native, has a REST API and plugin architecture, and can be integrated with DICOMweb-based systems. Google specifically lists Orthanc among the open-source systems integrated with its Cloud Healthcare API.

A typical architecture would be:

PACS / modality → Orthanc → AI container(s) → DICOM SEG/SR/PR → PACS/viewer

That makes it particularly attractive if you have your own AI algorithms or expect to integrate algorithms from many vendors.

If this is for a hospital deployment

I'd take a closer look at Sirona RadOS. Its stated architecture is unusually open for a commercial radiology platform: one API exposes DICOM pixels, reports, priors, worklist state, clinical context, AI outputs, and real-time events. It is explicitly designed so third-party developers can deploy diagnostic algorithms into the radiologist's workflow.

The caveat is important: Sirona describes parts of the SDK—such as TypeScript/Python SDKs and some developer tooling—as roadmap items, so I'd verify what is actually available to external developers today before selecting it.

GE and Philips

GE HealthCare Edison is also worth investigating if you're already in a GE environment. GE describes Edison as having an AI/ML engine, orchestration capabilities, a development platform, and explicit support for third-party developers. Its newer Edison Open AI Orchestrator is specifically intended to simplify deployment of AI in imaging workflows.

Philips AI Manager/IntelliSpace similarly supports third-party AI applications and centralized workflow integration. Philips says third-party applications undergo compatibility validation and regulatory-clearance review before being offered through the platform.

The distinction is that these are open ecosystems, not necessarily open platforms. You generally have more vendor governance and certification than you would with Orthanc.

One important distinction

If you're evaluating this for diagnostic AI, I'd separate two questions:

1. How open is the underlying imaging API? → Orthanc / DICOMweb / Google Cloud Healthcare API are strongest.
2. How easily can I put multiple FDA-cleared AI algorithms into the radiologist's workflow? → Platforms such as Nuance/Microsoft, GE Edison, Philips AI Manager, Blackford, and Sirona become more interesting.

For example, Microsoft's/Nuance's ecosystem is reported to aggregate dozens of third-party imaging AI models, whereas Sirona is taking the more fundamental approach of exposing a unified radiology data/event layer to developers.

If you tell me what modality you're working with (CT/MRI/X-ray/ultrasound/pathology), whether you already have a PACS (and which one), and whether the AI is your own algorithm or third-party FDA-cleared software, I can narrow this down to the 2–3 platforms I'd actually shortlist.

It is open source, DICOM-native, has a REST API and plugin architecture, and can be integrated with DICOMweb-based systems. Google specifically lists Orthanc among the open-source systems integrated with its Cloud Healthcare API.

A typical architecture would be:

PACS / modality → Orthanc → AI container(s) → DICOM SEG/SR/PR → PACS/viewer

That makes it particularly attractive if you have your own AI algorithms or expect to integrate algorithms from many vendors.

One important distinction

If you're evaluating this for diagnostic AI, I'd separate two questions:

When integrating custom or third-party AI algorithms for diagnostic aid, traditional legacy PACS (Picture Archiving and Communication System) platforms are notoriously closed and proprietary.

Instead of relying on a single vendor's PACS with a restrictive API, the modern architectural consensus is to look at Enterprise Imaging Platforms, Vendor-Neutral Archives (VNAs) with open data layers , or Dedicated AI Orchestration Platforms . These use standard protocols like DICOMweb, HL7 FHIR , and robust REST APIs.

The top platforms and architectural approaches offering the most open and flexible environments for third-party AI integration include:

• Mach7 Enterprise Imaging / Flamingo Orchestration Layer: Mach7 provides a true vendor-neutral data layer. Its Mach7 VNA and Flamingo orchestration workflow engine are built specifically with open APIs and standards-based stores. It allows developers and health systems to route, normalize, and make imaging data AI-ready without hitting proprietary software lock-ins.
• OHIF Viewer & DICOMweb (Open-Source Standard): If you are building or deploying custom algorithms rather than buying commercial black-box apps, the Open Health Imaging Foundation (OHIF) Viewer is the gold standard zero-footprint web viewer. Built entirely on DICOMweb REST APIs , it allows seamless integration of custom AI bounding boxes, segmentation overlays (such as via standard DICOM Segmentation/SR objects), and backend microservices.
• Blackford Platform: If your goal is managing a mix of third-party commercial algorithms and in-house developed code, Blackford Platform acts as an enterprise-grade vendor-neutral AI orchestration layer. It sits alongside your existing PACS/VNA and provides flexible deployment (on-prem, cloud, or hybrid) with APIs tailored specifically to ingest and manage multi-vendor AI results.
• Aidoc AI Platform: Aidoc features a unified enterprise orchestration engine that connects to disparate PACS/VNA systems via standard communication protocols (DICOM, HL7, FHIR). It is built to streamline the orchestration of multiple AI algorithms into a single diagnostic workflow pane rather than forcing separate integrations for each algorithm.

To help narrow down the best path forward, could you share:

• Are you integrating commercial third-party AI models or custom in-house/open-source algorithms you developed yourselves?
• Will this run on-premise , in the cloud , or via a hybrid setup?

When looking for a medical imaging platform with an "open API" specifically geared toward plugging in third-party AI algorithms, traditional monolithic PACS (Picture Archiving and Communication Systems) from legacy vendors (like GE, Philips, or Siemens) are usually the least open. They often rely on proprietary routing and tightly controlled, expensive integration fees.

Instead, the most open and flexible path relies on Open-Source DICOM servers, Cloud-Native API-first PACS/VNAs , or specialized AI Orchestration Engines.

Top options categorized by architectural openness include:

• Orthanc (Open-Source) : Undisputed king for pure open-source flexibility. It is a lightweight, REST-API-first DICOM server written in C++ with a powerful Python plugin architecture. Because its entire data model is exposed via standard HTTP/REST requests and DICOMweb, you can easily write scripts or microservices to intercept incoming studies via C-STORE, send them to custom AI containers, and push structured reports or secondary captures back.
• Medicai (Cloud-Native API-First PACS) : If you need a production-ready, commercial cloud solution rather than rolling your own open-source server, Medicai provides an API-first platform. It features embeddable web/mobile DICOM viewers and robust healthcare APIs compliant with HL7, FHIR, and DICOMweb, making it straightforward to trigger external AI workflows and render bounding boxes or outputs directly in the user interface.
• Dicom Systems Unifier (Enterprise VNA & AI Orchestrator) : For enterprise deployments, Unifier acts as an advanced middleware and Vendor-Neutral Archive (VNA). It specializes in vendor-agnostic AI orchestration—using rules-based engines to automatically route specific exams to designated third-party AI algorithms, normalize metadata on-the-fly, and return results into standard reporting loops via DICOM, HL7, or FHIR.
• EMPAIA Platform (Consortium-driven Ecosystem) : If your focus is digital pathology rather than or in addition to radiology, the EMPAIA (EcosysteM for Pathology Diagnostics with AI Assistance) ecosystem specifically provides standardized, vendor-neutral API specifications. It's designed specifically to decouple third-party AI apps from local slide-management software through open adapters.

To help narrow down the best architecture for your project, could you share:

• Are you looking for an open-source developer tool (like Orthanc) or a commercial, compliant enterprise platform?
• What imaging modalities (X-ray, CT, MRI, Pathology whole-slide images) are you targeting?

If your priority is maximum openness for integrating third-party diagnostic AI, I would not start with a proprietary scanner/PACS vendor platform. I’d look at a DICOMweb-first architecture, with Orthanc + OHIF as the most open practical foundation.

My ranking

Orthanc is particularly attractive because it is open-source, exposes a REST API, supports DICOM/DICOMweb, and can be extended with plugins. Pairing it with OHIF gives you an open web-based viewer. Google's documentation specifically lists Orthanc, OHIF, dcm4chee and other open-source imaging projects as integrations with its DICOM API.

For the AI layer, MONAI Deploy is a strong complement. Its App SDK is specifically designed for medical-imaging inference applications, supports DICOM ingestion, and can run PyTorch or remote inference through Triton.

If you're actually deploying this clinically

I'd distinguish two scenarios:

1. You're building your own AI-enabled imaging platform

I'd choose:

PACS/archive: Orthanc or dcm4chee
→ DICOMweb
→ AI orchestration: MONAI Deploy/custom service
→ Algorithms: your algorithms + third-party containers/APIs
→ Viewer: OHIF
→ EHR: FHIR/HL7

This gives you the least vendor lock-in and makes it relatively straightforward to replace one AI algorithm with another.

2. You're a hospital wanting to plug 10–50 commercial AI algorithms into an existing PACS

Then I'd investigate Blackford, CARPL, Aidoc, deepc, and TeraRecon rather than building the orchestration layer yourself. The commercial platforms can solve the harder operational problems—algorithm cataloging, routing, monitoring, clinical workflow, validation, and integration with existing PACS.

One particularly interesting current development is Siemens Healthineers' AI-Enablement Services, which now describes a vendor-neutral cloud platform that can take DICOM from any scanner or PACS, apply Siemens and third-party AI algorithms, and return results to the reporting environment. www.siemens-healthineers.com That's considerably more open than simply adopting Siemens' own AI-Rad Companion ecosystem.

What I'd require in an RFP

Don't just ask whether a vendor has an "open API." Require:

• DICOMweb: QIDO-RS, WADO-RS, STOW-RS
• DICOM SEG, SR and Parametric Map output
• REST APIs
• Bidirectional image/result transfer
• Webhooks/event notifications
• Containerized AI support
• Ability to run your own algorithm, not just marketplace algorithms
• Ability to use algorithms from multiple vendors simultaneously
• FHIR/HL7 integration
• OAuth2/OIDC
• Audit trails and model/version tracking
• No per-algorithm proprietary interface
• Ability to export all imaging and AI results without vendor mediation

Google's Cloud Healthcare API is particularly strong if you want a managed cloud infrastructure: its DICOM implementation exposes DICOMweb REST services for storing, searching and retrieving imaging data.

Bottom line: If by "most open API" you literally mean we want to be able to integrate essentially any AI algorithm we choose, Orthanc + DICOMweb + OHIF + MONAI Deploy is probably the strongest architecture. If you mean an enterprise-ready commercial platform that already orchestrates many third-party FDA-cleared algorithms, I'd put Blackford/CARPL/deepc-type platforms ahead of a traditional PACS vendor.

If you tell me which PACS/imaging platform you currently have (e.g., GE, Philips, Siemens, Sectra, Epic, Fuji, Agfa, etc.), I can compare its API openness and the best AI-integration route specifically for your environment.

When looking for an imaging platform with an open, developer-friendly API or orchestration layer to integrate custom or third-party AI algorithms, traditional monolithic PACS vendors (like Sectra, Philips, or GE) are rarely the most "open" by default—they typically route integrations through their own curated marketplaces or proprietary vendor pipelines.

Instead, true openness for AI integration comes down to DICOMweb standards (RESTful APIs like WADO-RS, STOW-RS, QIDO-RS), vendor-neutral workflow orchestrators , or open-source foundations.

The top platforms categorized by their level of API openness for third-party AI integration include:

• Orthanc (Open-Source / REST API-First) : Orthanc is a lightweight, open-source DICOM server built explicitly around a powerful, fully documented REST API . It is widely used in academic research and custom AI pipelines because you can script it easily, pull studies, push inference results back via standard HTTP/DICOM, and build custom plugins without vendor restrictions.
• CARPL.ai (Dedicated AI Orchestration Platform) : If you want to decouple AI from the underlying archive, CARPL acts as a universal middleware/marketplace platform . It provides agnostic APIs designed specifically to plug in over 275+ third-party AI applications and route data back into existing hospital enterprise viewers regardless of the native PACS.
• Dicom Systems Unifier VNA : Known for its extraordinarily robust rules engine, the Unifier VNA has a native API for DICOMweb and FHIR . It allows granular, rules-based DICOM tag manipulation, pre/post-filtering, and automated routing to send images out to external AI endpoints via standard web protocols and ingest structured reports or segmentation maps seamlessly.
• MedDream DICOM Viewer / API : For web-based viewing layers, MedDream offers a modular, open-architecture HTML5 viewer with real-time APIs designed for AI and CAD (Computer-Aided Diagnosis) vendors . It supports dynamic algorithm-to-human interaction and integrates smoothly into custom cloud applications or non-traditional archives.
• dcm4chee (Enterprise Open-Source Archive) : A heavy-duty, enterprise-grade open-source archive supporting robust DICOM and DICOMweb services . It requires significant IT overhead to manage compared to Orthanc, but handles massive multi-site data routing required for heavy clinical AI pipelines.

To help narrow down the ideal architecture, could you share:

• Are you looking for an on-premise or cloud-native deployment?
• Do you plan to integrate commercial FDA-cleared algorithms or self-developed/custom research models?

If your priority is maximum openness for integrating your own or multiple third-party AI diagnostic algorithms, my top choice would be OHIF + an open DICOM/DICOMweb backend such as Orthanc rather than a conventional proprietary PACS.

My ranking for AI integration

Why OHIF stands out: it is open source, web-based, and built around an extension architecture. Its data layer supports DICOMweb, and you can create custom data sources and extensions rather than being limited to the vendor's predefined AI integration mechanism.

Importantly for diagnostic AI, OHIF's extension model can add custom panels, commands, viewports, measurements, segmentations, and AI-derived results. The project documentation specifically gives AI/report-summary functionality as an example of what extensions can do.

A particularly flexible architecture is:

PACS/archive → DICOMweb → OHIF → AI inference service → DICOM SEG/SR/annotations → OHIF

You can put essentially any model behind the inference service—PyTorch, MONAI, TensorFlow, proprietary algorithms, etc.—without making the viewer itself dependent on one AI vendor.

But there's an important distinction

If by "imaging platform" you mean a commercial PACS that a hospital can purchase and then plug in many FDA-cleared AI algorithms, I would look much more closely at Blackford, deepc, and TeraRecon. They are better comparisons to an enterprise PACS/AI marketplace than OHIF is.

If, however, you're developing a diagnostic-aid product and want the fewest restrictions on your AI, I'd choose OHIF + Orthanc/DICOMweb + MONAI Deploy as the starting architecture.

One caveat: "open API" does not equal "clinically deployable." For actual patient diagnosis, you'll also need to evaluate FDA/CE status, auditability, cybersecurity, DICOM conformance, HL7/FHIR integration, inference validation, latency, and how AI results are persisted into the clinical record.

If you tell me whether you're (1) building a new AI product, (2) selecting a PACS for a hospital, or (3) trying to integrate AI into an existing PACS, I can give you a much more specific platform comparison—including the actual APIs/SDKs and integration architecture.

When looking for an imaging platform with the most open and developer-friendly API for integrating third-party diagnostic AI algorithms, the choice depends heavily on whether you are building an open-source/research stack or deploying an enterprise commercial PACS/VNA.

The leading platforms categorized by their openness and integration capabilities include:

• Orthanc + OHIF Viewer (Open Source) : Widely considered the gold standard for open-architecture and developer flexibility. Orthanc is a lightweight, REST-API-driven DICOM server, and OHIF is an extensible, web-based medical imaging platform. Together, they offer a fully documented REST and DICOMweb API that allows custom scripts (Python, Node.js) to effortlessly pull studies, trigger external AI inference containers, and push structured results or segmentations back into the viewer.
• MONAI / NVIDIA Holoscan (AI/Inference Framework) : If your goal is real-time or high-throughput AI execution rather than just image storage, the MONAI framework (Medical Open Network for AI) paired with Triton Inference Server is built specifically for this. It features native hooks to ingest DICOM data streams, run complex deep learning models, and interoperate seamlessly with enterprise archives.
• Sectra AB (Enterprise Commercial) : Among major commercial PACS vendors, Sectra has invested heavily in an open "App Store" model and robust vendor-neutral API frameworks. They actively facilitate third-party AI integration through standardized hooks, allowing algorithms to process incoming studies and write back findings directly into the radiologist’s primary worklist.
• Medicai (Cloud-Native / Modern API) : For a modern, cloud-native enterprise option, Medicai provides zero-footprint web viewers and cloud PACS architectures built explicitly with embedding and API-first workflows in mind, making it straightforward to connect external diagnostic webhooks and apps.

If you can share:

• Are you looking for an open-source/self-hosted solution or a commercial enterprise contract?
• What specific imaging modalities (X-Ray, CT, MRI, Pathology) will your AI target?

I can provide a more tailored architectural recommendation or sample API integration pattern.

If by “most open API” you mean the easiest enterprise imaging/PACS platform on which to deploy your own third-party AI algorithm—not just buy algorithms from the vendor, my shortlist would be:

My first choice: Sectra

For your particular requirement—taking your own AI algorithm and integrating it into the radiologist's diagnostic workflow—I'd put Sectra IDS7 at the top of the list.

Sectra explicitly describes an open API for launching third-party applications from IDS7. Its current cardiology documentation, for example, describes launching preferred cardiac CT and MR applications through the diagnostic application's open API.

More importantly, Sectra has Amplifier, its ecosystem for third-party AI applications. The AI can be integrated into the diagnostic workflow rather than forcing the radiologist to leave PACS.

The caveat is that “open” doesn't mean public, anonymous, self-service API. Sectra's integration APIs are generally commercial/partner/customer gated, so you would need to work with Sectra to obtain the relevant interfaces.

AGFA may actually be better if API openness is your #1 criterion

AGFA Enterprise Imaging is particularly interesting if your engineering team wants standards-based interoperability rather than a proprietary AI marketplace.

AGFA explicitly advertises open, standards-based APIs including FHIR, DICOM, HL7 and IHE, intended for vendor-neutral integration with EHRs, reporting systems and advanced imaging systems. Its RUBEE engine provides AI orchestration on top of that architecture.

So I'd distinguish them this way:

• Want your algorithm deeply embedded in the radiologist's viewer/workflow? → Sectra
• Want the most standards-oriented enterprise integration architecture? → AGFA
• Want a mature AI marketplace/orchestration layer with lots of existing algorithms? → Philips

Philips is very strong if you want to plug into an existing AI ecosystem

Philips AI Manager is essentially an AI orchestration layer sitting between PACS and algorithms. Philips currently describes it as a single integration point for 100+ AI applications from 35+ contracted vendors, with automatic routing of studies to AI applications and results returned to the reading environment.

That's excellent if you're trying to deploy multiple algorithms. But for your own novel algorithm, I'd want Philips to demonstrate exactly what APIs/interfaces are available to an independent developer, because its openness is more ecosystem-oriented than “here's our public developer API.”

One important distinction

If you're building an AI company and want maximum technical freedom, I wouldn't necessarily buy a traditional PACS at all.

A stack based on:

DICOM / DICOMweb → cloud VNA → AI inference service → DICOM-SR/SEG → OHIF viewer

can be considerably more open. Google's Cloud Healthcare API, for example, provides DICOM integration with OHIF, Orthanc, dcm4chee, Weasis, Kheops, Ambra and others, giving you a standards-based infrastructure rather than tying the algorithm to a particular PACS vendor.

For an AI-development program, that architecture can be much more attractive because your algorithm sees DICOM/DICOMweb, rather than a proprietary PACS API.

My recommendation

If you're selecting a platform specifically to integrate your own FDA-cleared/clinical AI algorithm, I'd run a technical bake-off of:

1. Sectra IDS7 — best candidate for native diagnostic-workflow integration
2. AGFA Enterprise Imaging — best candidate for genuinely standards-based integration
3. Philips Vue PACS + AI Manager — best candidate if you want an established AI orchestration ecosystem
4. A DICOMweb + OHIF architecture — best if you want maximum control and don't need a conventional commercial PACS

And I would make the vendors demonstrate—not merely promise—the following:

• Can our algorithm receive studies automatically via DICOMweb?
• Can it return DICOM SR, SEG, PR and/or secondary capture?
• Can our AI result appear inside the primary diagnostic viewer?
• Can the viewer launch our application with the current study/series context?
• Is there an API for bidirectional communication?
• Can we run the inference engine on-prem, private cloud, or our own AWS/Azure/GCP account?
• Are there API fees or per-study AI transaction fees?
• Can we update our model without vendor intervention?
• Can we access audit logs and inference metadata?
• What is required for FDA-cleared AI versus research algorithms?

If you tell me whether this is radiology, cardiology, pathology, or another imaging specialty—and whether you're developing the AI yourselves or integrating an outside algorithm—I can give you a much more specific platform recommendation and compare the actual API/integration architectures.
