Spine IMRT with TomoHelical

Targeting complex tumors with unmatched precision

TomoHelical™ Treatment Delivery, Accuray’s flagship helical delivery mode available for the Radixact® and TomoTherapy® Systems, sets the gold standard for treatment of complex spine tumors.

spine IMRT

A radical degree of freedom in dose delivery

TomoHelical combines 360-degree fan-beam delivery of intensity-modulated radiation therapy (IMRT) and megavoltage CT (MVCT) imaging. During treatment delivery, the linear accelerator completes multiple 360-degree rotations around the patient, while the couch passes through the center bore of the system.

Simplicity & speed

  • Continuous high-dose rate delivery enables for shorter beam-on times than most other radiation treatment systems.
  • Field lengths of to up to 135cms can be treated with no field junctions or patient repositioning.
  • Simultaneous irradiation of multiple target volumes.

Unmatched precision & dose fall-off

  • 360-degree treatment delivery provides highly conformal, uniform dose distribution while minimizing dose to surrounding normal structures.
  • TomoEDGE™ Dynamic Jaws dynamically conform to a target in the craniocaudal direction, producing share dose fall-off for precise sparing of normal tissue and increased throughput.
  • IMRT Planning Mode simultaneously modulates the beam along and across the treatment volume(s).

An ideal clinical solution for routine and complex indications

The Radixact® and TomoTherapy® platforms offer both 3D-CRT (TomoDirect) and IMRT (TomoHelical™) modalities, providing unique flexibility to treat the spectrum of spine cancer cases with exceptionally high accuracy and normal tissue sparing-from a single platform.

TomoEdge™ Dynamic Jaws

Total scheduled procedure time averages 10-15 minutes* with TomoEdge™ dynamic jaws

*Includes set-up, full 3D imaging and average beam-on time of 4.5 minutes. Total procedure times are approximate and based on internal Accuray test data. Times may vary with various clinical situations.
