Surface Guidance for Better Radiation Therapy Planning
Making Non-Coplanar Treatments Easier to Plan
MapRT® helps to make treatments fast, easy, and safe. It uses SGRT to deliver a “clearance map”, which planners use to check which beams are deliverable during plan creation. This is especially important for non-coplanar VMAT plans, which are becoming more popular due to the possibilities for organ-at-risk dose improvements.

MapRT images the entire surface of the patient and accessories to detect collisions in the most frequent problem areas, such as elbows. In addition, the clearance map checks safety for all couch and gantry angles, so planners have guidance to increase couch kicks and lengthen arcs – for better plans with confidence in delivery*.
MapRT Integration with RayStation®
“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.”
Helen Convery, Senior Dosimetrist (Development & Clinical Trials), Raigmore Hospital, UK.
Benefits of using MapRT:
“MapRT was also used to optimize the beam configuration for 165 plans (18.4%) in terms of rotations (gantry and couch) and arc amplitude.”¹
A recent study 2 showed improved assessment of deliverability using MapRT. Standard planning methods missed 11% of potential collisions and identified only 64% of clear beams/arcs. With MapRT 0% of potential collisions were missed and 100% of clear beams/arcs were identified.
With MapRT’s new Application Programming Interface (API)* you can integrate and extend your use of MapRT together with your Treatment Planning System.

“More freedom, better plans…better outcomes, less side effects.”
Kirsten Hierholz Senior Medical Physicist, Klinikum Darmstadt, Germany
“We see significant value in three areas: checking patient position at CT to ensure a robust setup and avoid unnecessary dose from scans in an unusable position; enhancing planning through increasing the range of beam options; improving the use of resources and the patient experience by avoiding dry runs and delays due to last minute replans.”
Helen Convery Senior Dosimetrist (Development & Clinical Trials)
“We succeeded in reducing the dose to the organs at risk while having the same coverage to the target and to the tumour, without huge additional time in terms of treatment. The quality of the treatment is improved, keeping the same level of security and delivering the treatment safety.”
Igor Bessières PhD Medical Physicist, Centre Georges-François Leclerc
Frequently Asked Questions
Capturing the entire patient and accessory surface during simulation typically takes 1-2 minutes. Some of the recent MapRT work has shown clinically meaningful plan improvements with a 30 second increase in treatment time 3. MapRT may help avoid the need for physical clearance checks, and with the new API (not currently for sale in the USA) enables clinics to create scripts within their Treatment Planning Systems which access clearance data.
MapRT is a very new technology but one paper, showing marked improvements in planning performance, is available here, as well as on our evidence page. Many users around the world are available to consult on the value of MapRT – contact Vision RT if you’d like us to arrange a reference site call.
Aside from RayStation, Eclipse® scripting with calls to the MapRT API is already being used in several sites to improve the planning process. Contact Vision RT for more details.
