RaySearch Laboratories and Vision RT Unveil Seamless Integration at ESTRO Conference in Vienna

At this week’s ESTRO conference in Vienna, RaySearch Laboratories and Vision RT proudly announced the next step in their collaboration: the full integration of MapRT with RayStation Treatment Planning System.

This integration enables full access to the MapRT clearance map in RayStation to guide the user during treatment planning in choosing beam trajectories clear from collisions between the treatment unit, patient, and couch.

During CT simulation, MapRT cameras capture the entire surface of the patient, along with any immobilization accessories. The MapRT software then analyzes this data, alongside models of the treatment couch and machine, to identify safe gantry and couch angles, which are represented by a clearance map that is immediately accessible in RayStation.

The integration is designed to optimize beam options for better plans and minimize the need for dry runs. This is particularly important for treatment plans where the couch is rotated. Recent studies have demonstrated that non-coplanar treatments can significantly improve treatment plans for several cancers, including lung^1,2,3,4, breast^5,6,7,8 head and neck cancers^{9,10,11,12,13}  lymphoma^14,15, and high-grade gliomas¹⁶. These treatments can offer clinically relevant benefits, such as improved organ-at-risk dose sparing.

Helen Convery, Senior Dosimetrist (Development & Clinical Trials), who has tested the integration, said, “We have used MapRT … at Raigmore Hospital since 2022 and have found it invaluable for checking for collision on all plans and optimising non-coplanar plan angles. I think the integration into RayStation is of significant value, and I can see it further streamlining and improving the efficiency of our workflow.”

Thomas Carter, VP of Marketing at Vision RT, added, “We are already seeing clinics changing their planning techniques, allowing their patients to benefit from the extra beam options MapRT provides. This integration has the potential to streamline workflows, reduce errors, and free up resources, all while improving treatment predictability. It also opens the path for automated, collision-free planning.”

Björn Hårdemark, RaySearch Deputy CEO, said “Surface guidance is an excellent source of information about the most central aspect of radiation therapy – the patient. The tight integration between MapRT and RayStation makes this information available already during treatment planning, allowing the user to explore more creative beam configurations while maintaining clearance around the patient. It is a great example of how clinical benefit can be achieved through collaboration between radiation therapy technology vendors.”

MapRT is approved for CE marking and clinical distribution in the EU and UK.

A version without the API is currently cleared for sale in the USA, with API version 510(k) pending.
