Efficacy of MLC based cobalt-60 plans: A DVH comparison and analysis with 6 MV plans
The purpose of this study was to compare 3D treatment plans implemented using 6 MV Linac with a retrofitted multileaf collimator (MLC) based cobalt-60 plans. In this retrospective study, DVH analysis was used to compare homogeneity of dose within the target and the dose received by critical organs. A prototype MLC designed and developed as a retrofit to current cobalt-60 teletherapy machines with a dedicated 3D treatment planning system was used. Cases representing 5 tumor sites like head& neck, glottis, lung, gall bladder, stomach were taken for the study, which were planned using Eclipse treatment planning system and treated with 6 MV photon beams.
