This webinar will share the results of End-to-End dose measurements for stereotactic radiosurgery quality assurance on a periodic basis. The RTsafe Prime anthropomorphic head phantom was used to verify the accuracy of single isocenter multiple metastases cases simulating each step of the SRS treatment chain. The unique characteristics of the Prime phantom in combination with the option for point, 2D and 3D dosimetry allow for a multilevel evaluation of SRS accuracy from imaging to dose planning and delivery.

The webinar, presented by Niko Papanikolaou and Daniel Saenz will cover:

  • Periodical End-to-End QA.
  • Verification of stereotactic radiosurgery accuracy.
  • Implementation of real 3D dosimetry.
  • Characteristics of Prime anthropomorphic phantom.
