The relationship between the phantom position and absorbed dose in the right breast was studied using optically stimulated luminescence dosimeters and a simulated human body phantom. The effect of position correction for CT dose index (CTDI) on SSDE was investigated in 51 patients who underwent right breast irradiation by comparing the SSDE with position correction and SSDE without position correction. The absorbed dose in the right breast tended to decrease by 10.2% as the phantom was placed away from the center of CBCT. The mean and standard deviation of SSDE were 2.54\u00a0\u00b1\u00a00.29 and 2.92\u00a0\u00b1\u00a00.30 mGy with and without position correction, respectively. The SSDE with position correction was 13.1% lower than that without position correction (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.05). SSDE was different when the patient's torso center was located at the isocenter of CBCT, and when it was not. The same tendency was seen in the case of the breast. Therefore, if the center of the patient is not at the acquisition center of the CT scanner, position correction is required when estimating SSDE.<\/jats:p>","DOI":"10.1002\/acm2.13851","type":"journal-article","created":{"date-parts":[[2022,11,30]],"date-time":"2022-11-30T10:43:42Z","timestamp":1669805022000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Accuracy of patient dose estimation in cone beam computed tomography in breast irradiation by size\u2010specific dose estimates with position correction"],"prefix":"10.1002","volume":"23","author":[{"given":"Hiroyuki","family":"Ueno","sequence":"first","affiliation":[{"name":"Division of Health Sciences Graduate School of Medical Sciences Kanazawa University  Kanazawa Japan"},{"name":"Department of Radiology Takaoka City Hospital  Takaoka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9933-0135","authenticated-orcid":false,"given":"Kosuke","family":"Matsubara","sequence":"additional","affiliation":[{"name":"Division of Health Sciences Graduate School of Medical Sciences Kanazawa University  Kanazawa Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sayuri","family":"Bou","sequence":"additional","affiliation":[{"name":"Department of Radiotherapy Takaoka City Hospital  Takaoka Japan"},{"name":"Department of Radiology Graduate School of Medical Sciences Kanazawa University  Kanazawa Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masato","family":"Hizume","sequence":"additional","affiliation":[{"name":"Department of Radiology Takaoka City Hospital  Takaoka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,11,30]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.lungcan.2006.11.012"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.radonc.2005.03.001"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.radonc.2005.03.026"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1186\/1748-717X-1-16"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-018-35875-6"},{"key":"e_1_2_11_7_1","volume-title":"Size\u2010Specific Dose Estimates (SSDE) in Pediatric and Adult Body CT Examination","author":"John MB","year":"2011"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1120\/jacmp.v14i3.4085"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.4947129"},{"key":"e_1_2_11_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/acm2.13282"},{"key":"e_1_2_11_11_1","unstructured":"International Electrotechnical Commission (IEC).Medical Electrical Equipment \u2010 Part 2\u201044: Particular Requirements for the Basic Safety and Essential Performance of X\u2010Ray Equipment for Computed Tomography.
