Our proven VMAT treatment planning algorithm is the most flexible solution available today, allowing clinicians to efficiently create high-quality single or multiple-arc plans for Elekta, Varian* and Siemens linacs.

Design and optimization of single- or multiple-arc plans is enabled. VMAT is planned through an optimization procedure (inverse planning).
Objectives and constraints for the desired dose are defined, and the system creates a plan that matches these criteria as closely as possible within the limitations of the treatment machine. The optimized plan is directly deliverable, without the need for post-processing that might degrade quality.
VMAT planning follow the same workflow as SMLC optimization. In addition it is possible to use delivery time and motion constraints.
The direct optimization of machine parameters means the optimized plan is directly deliverable with no quality-degrading post processing required. Varian, Elekta and Siemens machines are supported, including non-upgraded Varian machines and the Siemens mArc.
As the computation time is measured in seconds rather than minutes, you can efficiently produce several competing treatment plans to assess different trade-off situations instead of opening a second case or going on a break during computations. Download the study below and see how decreasing calculation times for VMAT planning significantly increased the fulfillment of clinical goals.
"RayStation is such an efficient tool, it is way faster than anything we’ve experienced before. Furthermore, the system is very intuitive and easy-to-use, and I don’t need to spend a lot of time to understand it. RayStation is a pleasure to work with. It is also a satisfaction to see that we get near perfect validation on our QAs for VMAT."

"Here at L’Hôpital Riviera, RayStation is our sole Treatment Planning System. Approximately 80% of our patients are treated with VMAT and we find that the plans are of excellent quality."
RayStation lets you can take constant dose rate VMAT to the next level thanks to smart optimization. Now you can reach plan quality equivalent to variable dose rate VMAT without an expensive hardware upgrade.
Using the powerful scripting and dose mimicking functionality unique to RayStation, we can create CDR plans that are comparable in plan quality to a variable dose rate plan, while still maintaining a high level of plan quality, and significantly shorter delivery times then what is typical for IMRT. The mean delivery times for tested prostate plans are between one and two minutes for both techniques, and between two and four minutes for the tested head and neck plans.
