Multiple modalities. Diverse treatment machines. Numerous software systems. There’s a lot to orchestrate if you want to reach the highs in treatment quality and efficiency. If that sounds like a familiar tune, take a look at RayStation 6. Now you have one control center for all your treatment planning needs – any equipment composition, any scale. RayStation has always led the way when it comes to technology integration, and now we’re proud to announce support for TomoTherapy systems*.

* Subject to regulatory clearance in some markets.

TomoTherapy Planning

In TomoTherapy, patients are scanned across a modulated strip-beam, so that only one section (Greek: tomo) is exposed at any one time by the linear accelerator (linac) beam. It is widely considered a versatile, efficient and effective way of treating cancer.

RayStation fully supports planning for TomoTherapy systems from Accuray, which designs and manufactures systems using image-guided, intensity-modulated radiation therapy (IG-IMRT) for streamlined clinical workflows and fully integrated treatment planning.

Users can efficiently design optimal treatment plans in TomoHelical and TomoDirect treatment modes with access to the advanced functionality of RayStation, including multi-criteria optimization, adaptive planning and plan explorer. RayStation also provides planning support for Synchrony® real-time motion synchronization.

Optimization capabilities for TomoTherapy include dynamic jaw support, delivery time constraints, and the possibility to specify regions where irradiation is avoided. TomoTherapy planning can be smoothly integrated into the clinical workflow and treatment plans are sent to Accuray’s integrated data management system for delivery (IDMS 1.1 or later is required).

MCO navigation for TomoTherapy

The inclusion of support for TomoTherapy in RayStation permits users to benefit from multi-criteria optimization (MCO). This allows for the continuous and immediate exploration of tradeoffs between planning objectives. TomoTherapy is an ideal treatment technique for MCO as navigated doses can be reconstructed by a deliverable plan to sub-percent accuracy.
An appropriate bound on the treatment delivery time can be identified through investigation of the tradeoff between delivery efficiency and plan quality during the creation of a deliverable plan.
