Significant new functionality includes treatment planning for Accuray's CyberKnife® System for radiosurgery and stereotactic body radiation therapy (SBRT). RayStation provides support for optimization with the three different collimation types - fixed cone, Iris™ and Incise™ Multileaf collimator -  and all CyberKnife tracking techniques for Synchrony® real-time motion synchronization. For ease of use, the planning workflow matches those for other treatment techniques in RayStation.

Support for CyberKnife planning is in line with RaySearch's ambition to unify treatment planning, eliminating the complications and additional steps that arise from using multiple software systems.

Further enhancements include support for multiple prescriptions, use of multiple GPUs in photon Monte Carlo dose calculation, faster optimization, and more efficient memory allocation. A new workflow feature is the possibility to define tolerance tables, which are specifications of permitted deviations from various machine settings. The tolerance tables can be selected during planning and exported with the plan, which simplifies treatment delivery.

The new RayStation version also adds further and tighter integration with the oncology information system RayCare®* and the treatment control system RayCommand®*, which help streamline the workflow in the clinic.

Johan Löf, founder and CEO, RaySearch, says: "RayStation 11A is an important step forward in our ongoing mission to unify treatment planning and support the widest range of treatment approaches possible. With the addition of CyberKnife planning, and greater integration with RayCare and RayCommand, we are bringing important benefits to both patients and clinicians."
