RaySearch at PTCOG 63

JUNE 3 – 6 | BUENOS AIRES, ARGENTINA | BOOTH #08

At RaySearch Laboratories, we transform energy into intelligence — enabling clinicians to harness protons, carbon ions, BNCT, and photons with greater precision, control, and adaptability.

Radiotherapy software has always been our core technology. Through advanced optimization algorithms and numerous lines of codes, our solutions shape emergent therapeutical energy into smarter, safer cancer treatments.

RaySearch products are subject to regulatory clearance in some markets. 
RayCommand is not for sale in the USA, Canada, Japan, and Argentina. RayCare is not for sale in Argentina. Its use and prescription will be subject to corresponding regulatory authorization. This information is intended exclusively for healthcare professionals for scientific and educational purposes.

Our mission is to convert raw treatment energy into optimized cancer care — through our advanced functionalities in particle therapy. Explore the highlighted functionalities we are bringing to PTCOG 63 with the full demo list further down below.

RayStation supports treatment planning for proton arc therapy, a technique that gives more conformal dose distributions and less dose to risk organs compared to conventional proton plans.

This technique has already been used for its first clinical treatments at the Trento Proton Therapy Center.

The static proton arc plans were optimized using RayStation and delivered with a significant improvement for head and neck cases. Read the full report here.

RayStation features a high-speed GPU-based Monte Carlo (MC) dose engine for proton pencil beam scanning (PBS) plans, supporting both final dose computation and optimization.

Speed is often subjective – but with RayStation, it is measurable:

  • MC final dose computation for a three-field IMPT head & neck plan (2.5mm voxels) with 0.5% uncertainty completes in 2.3 seconds
  • MC optimization completes in 82 seconds

All this computational speed comes with no compromise in accuracy.

In particle therapy, managing uncertainties is critical — from setup errors and density variations to anatomical changes. Conventional PTV-based planning often falls short in these complex scenarios.

RayStation addresses this with robust optimization, directly incorporating uncertainty scenarios into the planning process. To ensure confidence at every stage, our platform also provides comprehensive robustness evaluation tools across multiple error scenarios – helping clinicians assess and refine plan stability before delivery.

Wondering how we achieve this? Explore the article where we delve into detailed explanations of their underlying algorithms.

Upright treatment involves positioning the patient in a standing or seated posture, with radiation delivered from a fixed beamline – offering an alternative to conventional recumbent treatments.

RayStation supports upright treatment planning workflows, enabling precision planning for this emerging technique in particle therapy.

At RaySearch, we believe that collaboration is the catalyst for innovation in cancer care. By partnering with industry leaders, we aim to create interoperable solutions that prioritize patient needs and empower healthcare providers with the tools they need.

As a proud member of the UniteRT initiative, we are committed to fostering an open, vendor-agnostic ecosystem. This collaboration ensures that clinics have the freedom to choose the best solutions tailored to their unique needs, enhancing the quality and efficiency of patient care.

Together, through shared vision and cooperative efforts, we are transforming the landscape of particle therapy — a mission that echoes the spirit of PTCOG 63: Bridging Borders in Particle Therapy.
