Senseo haghoeji(2011)
摘要
In this study, we fabricated a fiber-optic phantom dosimeter by arraying square type of plastic optical fibers in a PMMA phantom for measuring relative depth doses of therapeutic photon beams. To minimize the cross-talk between fiber-optic dosimeters, we selected appropriate septum by measuring leaked scintillating lights according to the various kinds of septa. In addition, we measured percentage depth doses of 6, 15 MV photon beams using a fiber-optic phantom dosimeter.
