Cosylab Launches PlanOne™ Treatment Planning System for Particle Therapy

Cosylab today announced the commercial launch of PlanOne™, a treatment planning system for particle therapy, bringing physics-accurate, radiobiologically informed planning and a unified clinical workflow into a single environment. PlanOne™ is FDA 510(k) cleared.

"PlanOne™ began with listening. Over the years, our work on control systems in radiation oncology has put us in direct, ongoing contact with medical physicists and clinical teams at some of the leading facilities in the world," said Mark Pleško, CEO of Cosylab. "Our partners have been clear on what matters most for particle therapy: physics accuracy they can defend, clinical confidence at the point of plan approval, and a platform built to grow with AI and adaptive workflows. We designed PlanOne™ around those three priorities, and we'll keep developing it together with the clinical community that helped shape it."

Physics-accurate, radiobiologically informed planning

PlanOne™ is built on a GPU-accelerated Monte Carlo dose engine for particle therapy, which serves as the physical foundation for accurate LET calculation and variable RBE modelling*. Clinical teams can plan with confidence and can review plans within a single planning workflow.
