The sensor probes of the ultra-thin fiber-optic dosimeters consisted of very thin organic scintillators with thicknesses of 100, 150 and 200 \u03bcm. These types of sensors cannot only be used to measure skin or surface doses but also provide depth dose measurements with high spatial resolution. With the ultra-thin fiber-optic dosimeters, surface doses for gamma rays generated from a Co-60 therapy machine were measured. Additionally, percentage depth doses in the build-up regions were obtained by using the ultra-thin fiber-optic dosimeters, and the results were compared with those of external beam therapy films and a conventional fiber-optic dosimeter.<\/jats:p>","DOI":"10.3390\/s151129003","type":"journal-article","created":{"date-parts":[[2015,11,17]],"date-time":"2015-11-17T10:23:41Z","timestamp":1447755821000},"page":"29003-29014","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Feasibility of Ultra-Thin Fiber-Optic Dosimeters for Radiotherapy Dosimetry"],"prefix":"10.3390","volume":"15","author":[{"given":"Bongsoo","family":"Lee","sequence":"first","affiliation":[{"name":"School of Biomedical Engineering, College of Biomedical &amp; Health Science, BK21 Plus Research Institute of Biomedical Engineering, Konkuk University, 322 Danwol-dong, Chungju-si, Chungcheongbuk-do 380-701, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guwon","family":"Kwon","sequence":"additional","affiliation":[{"name":"School of Biomedical Engineering, College of Biomedical &amp; Health Science, BK21 Plus Research Institute of Biomedical Engineering, Konkuk University, 322 Danwol-dong, Chungju-si, Chungcheongbuk-do 380-701, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sang","family":"Shin","sequence":"additional","affiliation":[{"name":"School of Biomedical Engineering, College of Biomedical &amp; Health Science, BK21 Plus Research Institute of Biomedical Engineering, Konkuk University, 322 Danwol-dong, Chungju-si, Chungcheongbuk-do 380-701, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jaeseok","family":"Kim","sequence":"additional","affiliation":[{"name":"School of Biomedical Engineering, College of Biomedical &amp; Health Science, BK21 Plus Research Institute of Biomedical Engineering, Konkuk University, 322 Danwol-dong, Chungju-si, Chungcheongbuk-do 380-701, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wook","family":"Yoo","sequence":"additional","affiliation":[{"name":"School of Biomedical Engineering, College of Biomedical &amp; Health Science, BK21 Plus Research Institute of Biomedical Engineering, Konkuk University, 322 Danwol-dong, Chungju-si, Chungcheongbuk-do 380-701, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Young","family":"Ji","sequence":"additional","affiliation":[{"name":"Research Center for Radiotherapy, Korea Institute of Radiological and Medical Sciences, 215-4, Gongneung-dong, Nowon-gu, Seoul 139-706, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6597-2818","authenticated-orcid":false,"given":"Kyoung","family":"Jang","sequence":"additional","affiliation":[{"name":"School of Biomedical Engineering, College of Biomedical &amp; Health Science, BK21 Plus Research Institute of Biomedical Engineering, Konkuk University, 322 Danwol-dong, Chungju-si, Chungcheongbuk-do 380-701, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2015,11,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"599","DOI":"10.1016\/j.medengphy.2007.06.011","article-title":"In vivo measurements of the elastic mechanical properties of human skin by indentation tests","volume":"30","author":"Bec","year":"2008","journal-title":"Med.
