VMAT MADE FAST AND FLEXIBLE

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

VMAT planning

Design and optimization of single- or multiple-arc plans is enabled. VMAT planning is done using 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 follows the same workflow as SMLC optimization. Delivery time and motion constraints can also be used.

The direct optimization of machine parameters means the optimized plan is directly deliverable, with no post-processing required. Varian, Elekta and Siemens machines are supported, including non-upgraded Varian machines and the Siemens mArc.

As computation takes seconds rather than minutes, you can create several alternative treatment plans to assess different trade-off scenarios, instead of opening a second case or going on a break during computations. Download the study below to learn how faster calculation times for VMAT planning can significantly increase 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.”

Boost your linac with smart optimization

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 modern and innovative treatment planning tools, it is possible to create deliverable Split Constant Dose Rate (SCDR) plans with comparable quality to Variable Dose Rate (VDR) plans, without upgrading the linac to VDR. The delivery times for both VDR and the SCDR plans are significantly shorter than what is typical for IMRT plans. 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.
