However, AEC devices are not being used in portable X-ray systems due to technical issues.<\/jats:p>\n <\/jats:sec>\n \n Purpose<\/jats:title>\n To evaluate the radiation dose and image quality of a new AEC for a wireless portable X-ray system compared to the standard fixed radiation dose of manual controls in chest radiography.<\/jats:p>\n <\/jats:sec>\n \n Material and Methods<\/jats:title>\n This retrospective analysis evaluated the performance of a portable X-ray system equipped with software-based AEC on anteroposterior chest radiographs. A quantitative evaluation comparing the manual and AEC groups was conducted to ascertain the exposure index (EI) and dose-area product (DAP). We performed observer-based analysis of image quality for lowest exposure and average exposure images in the manual and AEC groups.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Overall, 2093 examinations were conducted in 467 patients. AEC yielded a statistically significant reduction in the DAP (AEC: 1.64 dGycm\n 2<\/jats:sup>\n ; manual: 1.99 dGycm\n 2<\/jats:sup>\n ) and EI (AEC: 266; manual: 393) compared to manual control (\n P<\/jats:italic>\n \u2009<0.001). Evaluation of the average and low exposure images revealed that the DAP and EI were consistently lower in the AEC group (\n P<\/jats:italic>\n \u2009<0.01). Observer-based analysis of the lowest exposure images revealed that AEC yielded a statistically significant higher score compared to manual control (12.5 manual, 13.4 AEC;\n P<\/jats:italic>\n \u2009<0.001).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n AEC within a wireless portable X-ray system improves subjective image quality while reducing radiation exposure, as substantiated by quantitative and qualitative metrics.<\/jats:p>\n <\/jats:sec>","DOI":"10.1177\/02841851251387448","type":"journal-article","created":{"date-parts":[[2025,10,27]],"date-time":"2025-10-27T17:17:08Z","timestamp":1761585428000},"page":"60-66","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Efficacy of a new detector automatic exposure control in portable anteroposterior chest radiography: a retrospective examination of radiation dose optimization and image quality"],"prefix":"10.1177","volume":"67","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5960-0719","authenticated-orcid":false,"given":"Yoon Ki","family":"Cha","sequence":"first","affiliation":[{"name":"Sungkyunkwan University School of Medicine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jung Han","family":"Woo","sequence":"additional","affiliation":[{"name":"Chung-Ang University Hospital"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dong Hyuk","family":"Kim","sequence":"additional","affiliation":[{"name":"Health & Medical Equipment Business, Samsung Electronics Co., Ltd, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sanguk","family":"Kim","sequence":"additional","affiliation":[{"name":"Health & Medical Equipment Business, Samsung Electronics Co., Ltd, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dong Hun","family":"Lee","sequence":"additional","affiliation":[{"name":"Health & Medical Equipment Business, Samsung Electronics Co., Ltd, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6271-3343","authenticated-orcid":false,"given":"Myung Jin","family":"Chung","sequence":"additional","affiliation":[{"name":"Sungkyunkwan University School of Medicine"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,10,27]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1088\/0031-9155\/51\/21\/006"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.145.3.7146417"},{"key":"e_1_3_2_4_2","unstructured":"International Electrotechnical Commission.
