이윤석,Lee, Yun-Seok 대한방사선치료학회 2005 대한방사선치료학회지 Vol.17 No.1
Purpose : Wish to present degree management process that is efficient confirm radiation treatment exclusive use CT simulator's Q.A item that become Q.A and Differentiation of diagnosis area that present Report of the AAPM Task Group No.66 using Q.A tool that produce itself and secure safe and correct CT-simulation process and equip convenience. Method and material : Manufacture CT simulator's Q.A tool on source and confirm virtue between isocenter of wall laser system, patient table, CT scanner's imaging plane that present in Report of the AAPM Task Group No.66 by daily publication unit. Result : Confirmed measured value from Report of the AAPM Task Group No.66 to confirmation of presenting degree management item in wall laser's ${\pm}2mm$, table's ${\pm}2mm$, imaging plane's ${\pm}2mm$ tolerance extent. Conclusion : There is unconfirmed item from CT-simulation process for therapy to CT Q.A protocol of existent diagnosis area, premising suitable degree management of radiation treatment exclusive use CT-simulator equipment confirming presenting Q.A item in Report of the AAPM Task Group No.66 safe and correct CT-simulation process guarantee can
