The results of this study showed that the great difference of output factor for two collimators is fixed collimator higher than 25.88% with Iris in 5 mm cone size and in SAD 800 mm, and 3.4% for 7.5 mm cone size. The other output factor differences between fixed and Iris are all less than 1%. The biggest different of penumbra of fixed and Iris are in 50 and 60 mm cone sizes.","PeriodicalId":340479,"journal":{"name":"2016 3rd International Conference on Green Technology and Sustainable Development (GTSD)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128785891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
