A concept of radiation beam matching of some medical linear accelerators (LINACs) that have identical characteristics of the models, radiation quality, and multileaf collimator features may be implemented as long as the manufacturer provides complete specifications so that a Treatment Planning System (TPS) can be used for many beam-matched LINACs. This paper describes a preliminary study on the implementation of the beam matching concept for five units Elekta Precise Treatment System LINACs that have recently been installed in Indonesia. The beam matching criteria were based on the percentage depth dose (PDD) and beam profile for photon and electron beams. Dosimetry measurements were carried out by using an SNC 125 ionization chamber of 0.125 cm 3 in volume, PTW Pinpoint 3D of 0.016 cm 3 in volume, and PTW Farmer Chamber of 0.6 cm 3 in volume. The results indicated that the PDD 10 of 6 and 10 MV photon beams among installed five units LINACs have excellent compatibility each others with a maximum deviation of less than 0.4 %, while the maximum deviation for dose depth of 80 % (R 80 ) for the electron beams with nominal energies of 4, 6, 8, 10, 15 and 18 MeV is 1 mm. The measurement results for the flatness profile were less than 6 %, and symmetry profiles were less than 3 %. It also outlines the determination of the absorbed dose to water under reference conditions. The results of the calibration of output doses show that the absorbed dose in the water was 1 cGy ≈ 1 MU. The data obtained from measurements for each LINAC conform with the requirements of the beam matching process set by the manufacturer.
一些具有相同模型、辐射质量和多叶准直器特征的医用直线加速器(LINACs)的辐射光束匹配概念可以实施，只要制造商提供完整的规格说明，以便治疗计划系统(TPS)可以用于许多光束匹配的直线加速器。本文描述了最近在印度尼西亚安装的5台Elekta精确处理系统LINACs的光束匹配概念实施的初步研究。光束匹配标准基于光子和电子束的百分比深度剂量(PDD)和光束轮廓。剂量测定采用体积为0.125 cm 3的SNC 125电离室、体积为0.016 cm 3的PTW Pinpoint 3D电离室和体积为0.6 cm 3的PTW Farmer电离室进行。结果表明，6 MV和10 MV光子束的PDD 10在安装的5台LINACs之间具有良好的兼容性，最大偏差小于0.4%，而标称能量为4、6、8、10、15和18 MeV的电子束的剂量深度最大偏差为80% (r80)为1 mm。平整度轮廓的测量结果小于6%，对称性轮廓的测量结果小于3%。它还概述了在参考条件下对水的吸收剂量的测定。输出剂量的标定结果表明，水中的吸收剂量为1 cGy≈1 MU。从每个LINAC的测量中获得的数据符合制造商设定的光束匹配过程的要求。
