Leo Cancer Care

Leo Cancer Care decided to work with Cosylab and ArrowFast due to their flexibility and willingness to really become part of our team. Cosylab and ArrowFast have a huge amount of experience developing complex software for the heavily regulated medical field. This experience means they have a deep level of understanding when it comes to appropriate system architecture and the necessary regulatory deliverables.

Working with Cosylab and ArrowFast has been a real partnership and one that has allowed us to leverage the vast experience of their HW and SW engineers to dramatically reduce our time to market.

Proton VDA

Moving our novel medical imaging system from the prototype stage into the clinic requires a set of skills in systems engineering, integration, regulatory practice, and marketing. Cosylab and Arrow Fast have brought these skills to our partnership and they have proved critical for growing our business at Proton VDA and opening new markets.

Their detailed understanding of patient safety aspects and device usability combined with broad experience and expertise in proton therapy instrumentation and controls enabled a rethinking of our system architecture and integration with treatment rooms. Their diligent and rigorous following of regulatory practices give us the confidence ahead for the certification process. Their extensive contacts in the radiation therapy industry are helping us work with clinical groups to plan ahead for the use of our technology for improved patient care.
