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.

The tests proposed are useful for 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 1 mm calculation grid. • Eclipse TPS commissioning for two TrueBeams • Mobius3D commissioning for two TrueBeams • Eclipse TPS upgrade • Beloit Memorial Hospital • Pinnacle TPS upgrade • Mobius3D commissioning for Elekta Infinity • University of Wisconsin Hospital • Pinnacle TPS commissioning for one TrueBeam The dosimetric leaf gap (DLG) and multileaf collimator (MLC) transmission are two important systematic parameters used to model the rounded MLC leaf ends effect when commissioning an Eclipse treatment planning system (TPS). Determining the optimal DLG is a time consuming process. This study develops a simple and reliable method for determining the DLG using the cross-field dose width.

Because the OCR calculated using the Eclipse TPS showed the fluctuated profile, the values were normalized by the mean value in the range ± 10 cm. In the range ± 80 cm from the central axis, the differences between the measurements and TPS at measured points were within 1% and 1.8% for AAA and AXB, respectively. Third, the Varian Eclipse TPS was commissioned through five sets of data collections (in-water Bragg peak scans, in-air longitudinal fluence scans, in-air lateral profiles, in-air half-beam profiles, and an HU-to-stopping-power conversion curve) and accuracy of TPS calculation was tested using in-water scans and dose measurements with a 2D array detector with block and range compensator. A 60×60×60 cm(3) solid water cube was created in Varian Eclipse TPS. Beam data profiles (crossline and diagonal) and PDDs for field sizes ranging from 2×2 cm(2) to 40×40 cm(2) were simulated.
