Analyze the Dose Results Calculated with AAA Algorithm in Eclipse Software of New Treatment Planning System

摘要

In this paper,the authors investigate the differences between the dose results calculated with AAA(Anisotropic Analytical Algorithm)algorithm in Eclipse 13.0 treatment planning system,which has just commissioned,with the measured doses.The AAA algorithm in the Eclipse software is used to calculate the absolute dose,relative dose in profile line,and percent depth dose of some specific field size in Blue Phantom.The calculated dose results were compared with measured dose based on Technical Reports Series No.430 of International Atomic Energy Agency(IAEA No.430).The authors have used CC13 ion chamber,Famer Chamber,water phantom,and Omnipro software to measure relative,absolute doses of these fields size.The AAA algorithm was also used to calculate the doses in IMRT(Intensity Modulated Radiotherapy)plan of fifty head and neck cancer patients.These IMRT plans were controlled quality in some points with plastic phantom,and famer chamber FC65.The differences between calculated dose,and measured doses are in the limit of IAEA 430 report.The results of the QA IMRT plan processing are fitting with ESTRO(European Society Therapeutic Radiation Oncology)Booklet No.9.
