METHODS: We introduced commissioning errors into the commissioning process for the Anisotropic Analytical Algorithm (AAA) within the Eclipse TPS. We included errors in Dosimetric Leaf Gap (DLG), electron contamination, flattening filter material, and beam profile measurement with an inappropriately large farmer chamber (simulated using sliding window smoothing of profiles).

The measured data were imported into Eclipse TPS to build a VersaHD beam logfile‐based quality assurance tool, was also commissioned both for routine

2. MATERIALS AND METHODS The commissioning of the PBC algorithm of the Eclipse TPS was performed in two stages. In the first stage, we used a specific workspace of the TPS itself, called Beam Analysis [3], in which the system calculates the depth doses and the beam the commissioning of TPSs and for the validation of major upgrades. With the ECLIPSE TPS, relevant differences were found between calculations and measurements for beams with dynamic MLCs in the presence of the TG effect, especially for the High Definition MLC, small gap sizes and the 1mm calculation grid.

Conclusion: When Eclipse is commissioned with GBD it was quite accurate, however, commissioning with measured data can improve the overall match. Conflict of Interest:Funding provided by Varian. Purpose: Evaluation of the accuracy of Eclipse AAA TPS when commissioned with Golden Beam or … The Eclipse v.10 TPS was commissioned at the Princess Alexandra Hospital by comparing calculated and Percentage Depth Dose (PDD) profiles with measured data for 6MV, 10MV and 15MV for various Eclipse TPS algorithm manual. Field sizes ranged from 1 × 1or2×2to40× 40 cm2 and were determined by the jaw settings (i.e., data were acquired with the MLCs parked). All mandatory and recommended beam data mea-surements (PDDs, crossplane and inplane proﬁles) were per-formed, as speciﬁed inthe Eclipse manual for commissioning AAA. We also evaluated the calculation accuracy of the Eclipse TPS. For the RANDO phantom, the TPS calculation showed good agreement with the IVD-measured dose within 5%. For patients, the AAA calculation showed agreement within 10%.

Introduction: Varian Eclipse version 10 (v.10) Treatment Planning System (TPS) that employs the Analytical Anisotropic Algorithm (AAA) to calculate photon beam distribution in a medium was The aim of this study was to report a single-institution experience and commissioning data for Elekta VersaHD linear accelerators (LINACs) for photon beams in the Eclipse treatment planning system (TPS). Two VersaHD LINACs equipped with 160-leaf collimators were commissioned. For each energy, the pe … 2.5 Varian Eclipse TPS commissioning 2.5.1 Beam modeling and DLG optimization using MatriXX. Next step involved importing measured beam data into Eclipse TPS for beam modeling.

Provide updated guidance on technologies that are newer 3. Provide guidance on validation tests for dosimetric accuracy 4. If the TPS is being commissioned in parallel with the commissioning of a new linear accelerator, then a full set of new modeling data is required. If a new TPS and/or new algorithm are being commissioned on an existing linear accelerator, then existing data could be used, provided they are verified (compared with recent QA measurements to assess any changes in beam characteristics) and meet vendor … Commissioning of the algorithms in Eclipse TPS for HyperArc: 1) Configuration of AAA and/or Acuros® XB photon dose calculation algorithm: Beam configuration should follow the guidance given in the Eclipse™ Photon and Electron Algorithms Reference Guide, V15.5 and newer at www.myvarian.com A single beam model is I have led each of these projects from shielding design and review, accelerator specifications, acceptance testing and through commissioning. My team and I commissioned the accelerators and Varian Eclipse TPS for general external beam treatment including stereotactic delivery (SRS and SBRT), prone breast, DIBH, and gated treatment deliveries.
