Established vendors

The engineering partner radiation therapy device manufacturers rely on. 

Radiation therapy device manufacturers don't need more engineers. They need a partner who understands the domain, takes full responsibility for delivery, and stays for the long term. We bring 25 years of complex systems engineering - across particle accelerators, fusion, and radiation therapy - with domain continuity built into how we work, not dependent on individual people.
System engineering and full delivery ownership.

We help you define the problem before a single line of code is written. System architecture, project definition, risk ownership – all on us. We build and maintain real-time control systems across ACS, DDS, TCS, RDS, and ICS, with IEC 62304 Class C implementation and documentation as part of the process, not an afterthought. 

Legacy systems maintained and evolved. 

Legacy systems don’t disappear; they accumulate risk. End-of-life components, outdated architectures, and evolving regulatory requirements turn maintenance into a liability. We maintain and incrementally modernize systems with minimal machine downtime, preserving operational behavior and regulatory compliance throughout, while adding new clinical capabilities that the original system was never designed to support. 

Automated end-to-end testing. 

In safety-critical environments, testing is a discipline, not a phase. We build automated test frameworks together with continuous integration to make every regulatory submission more defensible and turn validation from a bottleneck into a competitive advantage.

Startups

From prototype to certified clinical system

Getting from 'it works in the lab' to 'it works in a hospital' is a fundamentally different engineering problem. We bring the architecture, regulatory discipline, and execution experience that most startups don't yet have in-house - built in from day one, not retrofitted under deadline pressure.
Faster time to market.

We help you get to market faster by building on production–ready platform components and a proven track record of delivering complex RadOnc systems. You are not architecting from zero in a domain where every month of delay costs runway.

Milestone-aligned development.

We structure our engagement around your funding milestones, so every deliverable lands at the right moment in the funding cycle. We help founders decide what to build and when – not just execute against a spec. 

Regulatory compliance built in.

ISO 13485, IEC 62304 Class C, FDA/MDR documentation – integrated into development from day one, not as a late–stage audit exercise. When the time comes to submit, you will be ready with everything you need. 

“Manufacturers of innovative and complex medical devices face the same challenges when planning a timely launch of their certified product to the market. I believe we chose wisely in deciding to partner with Cosylab, as we were seeking rapid development iterations, clear communication, proactive, flexible and skilful problem-solving, and effective solution delivery. With Cosylab, we gained all of these and more.”
