A comparative study on 6 MeV photon beam percentage depth dose of VARIAN CLINAC 2300 c/d, ELEKTA synergy platform, and Siemens Primus LINACS

摘要

This work presents a comparative study of the 6 MeV percentage depth dosecurves for photon beams of VARIAN Clinac 2300 C/D, ELEKTA Synergy Platform,and SIEMENS Primus Linacs. The measurements were performed for a set of 7 fieldsizes (55, 1010, 1515, 2020, 2525, 3030, 4040) cm2, keeping thesame conditions (e.g., geometry, ion chamber voltage and polarity, incremental step anddirection). During our study we used the Mephysto MC2 software and two semiflex ionchambers from Physikalisch-Technische Werkst tten GmbH, calibrated in water under60Co gamma ray beam.
