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.
