Abstract

The purpose of the study was to determine the value of PDD against energy variations in the electron beam using the Elekta Precise Brand LINAC aircraft, and to determine the suitability of the PDD value against energy variations in the electron beam with the standards set by AAPM. PDD value data obtained from the results of research using Sun Nuclear Dosimetry Software (SNC Dosimetry). The results of the study will then be compared with the standard Tolerance value set by AAPM of a maximum of 2%. From the deviation value of each 4 MeV energy is 1.1% - 1.8%, 6 MeV energy is 1.1% - 1.6%, and 8 MeV energy is 1.0% - 1.2%, the deviation error at 4, 6, and 8 MeV energy is in accordance with the tolerance limit set by AAPM which is 2%. So that the Elekta Precise LINAC machine at the Radiotherapy Installation of Prof. Ngoerah Denpasar Hospital is feasible to operate to receive patients.

使用LINAC品牌Electa precision机器对美国医学物理学家协会(AAPM)放射治疗装置中电子束能量变化的百分比深度剂量(PDD)的依从性测试

本研究的目的是使用Elekta Precise Brand LINAC飞机确定PDD值对电子束能量变化的影响，并根据AAPM设定的标准确定PDD值对电子束能量变化的适用性。PDD值数据来自使用Sun核剂量测定软件(SNC剂量测定)的研究结果。然后将研究结果与AAPM设定的最高2%的标准公差值进行比较。从4 MeV能量的偏差值为1.1% ~ 1.8%，6 MeV能量的偏差值为1.1% ~ 1.6%，8 MeV能量的偏差值为1.0% ~ 1.2%来看，4、6、8 MeV能量的偏差误差符合AAPM规定的2%的容差限值。因此，Ngoerah Denpasar教授医院放射治疗装置的Elekta精密LINAC机器可以操作以接收病人。

期刊介绍： The SEAMEO* Regional Tropical Medicine and Public Health Project was established in 1967 to help improve the health and standard of living of the peoples of Southeast Asia by pooling manpower resources of the participating SEAMEO member countries in a cooperative endeavor to develop and upgrade the research and training capabilities of the existing facilities in these countries. By promoting effective regional cooperation among the participating national centers, it is hoped to minimize waste in duplication of programs and activities. In 1992 the Project was renamed the SEAMEO Regional Tropical Medicine and Public Health Network.
