Symmetry - managing respiratory motion

Symmetry uses unique anatomically correlated 4D image guidance at the time of treatment to give volumetric visualization of respiratory motion and the ability to correct for baseline shifts.

Accounting for baseline shift will support delivery of treatments with only small margins required for free breathing. Gating or tracking are not required.

  • Helps achieve symmetrical dose distribution for a variety of planning techniques, including ITV
  • Uninterrupted patient set-up and treatment delivery
  • Accounts for baseline shift
  • Enables margin reduction
  • Simple intuitive workflow
  • Ideal for SBRT


Symmetry is not available for sale or distribution in all regions. Please contact your local Elekta representative or authorized distributor for more information. Symmetry is a feature set of XVI R4.5.
