SGRT for Clearance Mapping
Recent studies show that non-coplanar treatments can deliver clinically relevant improvements to treatment plans¹⁻¹³. Traditionally, non-coplanar treatments require extra planning and machine time, both for dry runs and treatments. Additionally, some noncoplanar plans are not deliverable, which can lead to complicated re-planning and repeat quality assurance work, leading to delays in patient treatment and increased costs.
MapRT is intended to make non-coplanar 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.
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 introduces Clearance Mapping to RT planning.
How MapRT works:
MapRT uses two lateral wide-field cameras in simulation to deliver a full 3D model of patients and accessories. This model is then used to calculate a clearance map for every couch (x-axis) and gantry (y-axis) angles. Plans can then be imported automatically to check beams, arcs, and the transition clearance.
MapRT can automatically receive and process DICOM RT plans from Eclipse®, Monaco®, Pinnacle®, and RayStation®.
“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.”

Improved assessment of deliverability
A five-center planning study¹⁴ recently showed improved assessment of deliverability using MapRT:
Non-coplanar treatment planning using clearance mapping has shown the potential to enhance outcomes, as shown in this planning study¹⁵ of head and neck retreatments:
