Scaling global radiology access: medavis and DataArt build on AWS

As part of the Synava Group—a leading European IT platform for radiological processes and specialized clinical solutions—medavis faced a strategic turning point. Its radiology information systems had been successfully deployed across hundreds of sites in Germany, but the underlying delivery model—highly customized, on-premises installations—resulted in significant operational complexity. Each deployment required individual configuration, creating a fragmented landscape that was costly to maintain, difficult to standardize, and inherently limited in scalability. This model constrained growth, slowed down innovation cycles, and made international expansion practically unfeasible.

At the same time, medavis recognized a structural imbalance in the global healthcare system: Although imaging devices are widely available, access to qualified radiologists remains unevenly distributed. Even within Germany, rural regions struggle to attract specialists, while urban centers concentrate expertise. Internationally, this gap becomes even more pronounced, with entire regions lacking access to diagnostic capabilities. Existing approaches to bridge this gap are often informal, nonscalable, and noncompliant. “We had discussions with a physician from Munich who was helping people in Tanzania by providing medical reports through a messaging service,” says Ehsan Esmaili, product manager at medavis. “We knew that there was a better solution.” medavis identified an opportunity to fundamentally rethink radiology delivery—transforming localized workflows into a scalable, cloud-based platform that enables secure, standardized, and cross-border diagnostic collaboration.

To address the lack of secure, structured systems for cross-border collaboration, medavis set out to build radiance365, connecting imaging providers with remote radiologists through a standardized architecture. The company sought a partner with experience in designing and operating cloud workloads at scale to guide both technical and organizational change. medavis selected DataArt for its healthcare domain expertise, cloud architecture capability, and consultative approach. DataArt assembled a cross-functional team of solutions architects, user experience and interface specialists, DevOps engineers, and a business analyst. Following structured 3-week sprint cycles, the teams moved through alpha and beta phases, delivering a minimum lovable product in about 2 years. “Working with DataArt never felt like a classic vendor relationship, but more like a partnership,” says Esmaili. “The collaboration was open and transparent. There was good alignment between architecture, product, and business.”

To orchestrate multiple backend services to manage authentication, workflow coordination, and system integration, radiance365 uses Amazon Elastic Kubernetes Service (Amazon EKS)—a managed service for building, running, and scaling production-ready Kubernetes applications. For secure communication between on-premises environments and the cloud backend, the solution relies on Amazon API Gateway—a fully managed service that makes it simple for developers to create, publish, maintain, monitor, and secure APIs at nearly any scale. By deploying a lightweight piece of software acting as a local gateway on their on-premises IT infrastructure, clinics can connect existing imaging systems and securely upload imaging files to Amazon Simple Storage Service (Amazon S3)—object storage built to store and retrieve virtually any amount of data from anywhere. By integrating a full diagnostic viewer from MedDream—a Synava Group company with FDA-cleared and medical device–certified technology—medavis extends radiance365 beyond simple image access to a comprehensive reporting environment. The viewer retrieves imaging data from Amazon S3, helping radiologists to perform high-resolution image interpretation and complete diagnostic reporting workflows remotely, without reliance on local workstation infrastructure.

With radiance365 in place, medavis introduced a cloud-based teleradiology solution that replaces fragmented and informal image-sharing practices with structured, compliant workflows. The solution supports diagnostic exchange across borders, demonstrating its ability to operate beyond a single national market and connecting more than 400 radiology providers across three continents. A radiologist in France can now write reports for patients in Congo, and a specialist in Germany can provide reads for a rural clinic that can’t attract onsite talent.

Beyond supporting new clinical workflows, the transition to a cloud-based, multitenant architecture fundamentally changed how medavis scales its business. By moving away from individually configured on-premises installations to a centralized platform, the company significantly reduced deployment complexity and operational variability across customers. New sites can be onboarded more efficiently, and standardized workflows can be reused across deployments, accelerating time to value. At the same time, the platform opens up new growth opportunities beyond traditional radiology, including veterinary and dental imaging, supporting medavis’s expansion into new markets while maintaining compliance and governance standards. “Moving to the cloud is not only a technical change but also a mindset shift that affects the whole business,” says Esmaili.
