Abstract

The purpose of this study is to investigate the calibration of an optically stimulated luminescent nanoDot dosimeter(OSLnD) to 6 MV photon beam. Dose ranges of the calibration of linear and non-linear from the analysis of dose response of the OSLnD were decided. To evaluate the accuracy of calibration equation and the calibration, the sets of the calibration and quality control dosimeter were used to make. The calibrations were performed by the linear and the non-linear in the dose range of 0~300 cGy and 20~1300 cGy, respectively. The errors of the calibration were acquired less than 0.1% respectively from the measurement of the quality control dosimeters for the calibration of linear and the non-linear. This study provides the calibration equation of the OSLnD to the 6 MV photon beam.

이 연구의 목적은 6 MV 광자 빔에 대한 광자극형광나노닷선량계(OSLnD)의 교정을 조사하는 데 있다. OSLnD의 선량반응 분석으로부터 선형 및 비선형 교정의 선량범위들은 결정을 하였다. 교정 및 교정식의 정확성을 평가하기 위하여 교정 및 품질관리선량계의 세트들은 만들어서 사용하였다. 교정들은 각각 0~300 cGy 및 20~1300 cGy 선량범위에서 선형 및 비선형적으로 수행하였다. 교정의 오차들은 선형 및 비선형 교정에 대하여 품질관리선량계들의 측정으로부터 각각 0.1% 이하로 얻었다. 이 연구는 6 MV 광자 빔에 대한 OSLnD의 교정식을 제공한다.
