This study investigates a CT-specific, operational air kerma\u2013area product derived from time-resolved measurements using small solid-state dosemeters mounted at the gantry aperture. A mathematical framework is presented that accounts for tube rotation, bow-tie filtration, beam geometry, and the longitudinal dose profile. Model validation was performed using measured air-kerma rate waveforms under free-in-air and phantom conditions, demonstrating that a reproducible kerma\u2013area quantity can be derived from fixed-detector measurements. By excluding the kerma\u2013area contribution associated with radiation that does not intersect the object, the proposed approach yields a quantity that is more closely related to patient-incident radiation than conventional output-based KAP concepts in CT. The methodology provides a practical tool for system characterization and quality control in CT dosimetry.<\/jats:p>","DOI":"10.1093\/rpd\/ncag010","type":"journal-article","created":{"date-parts":[[2026,1,20]],"date-time":"2026-01-20T12:28:43Z","timestamp":1768912123000},"page":"358-370","source":"Crossref","is-referenced-by-count":0,"title":["Assessment of air kerma\u2013area product in computed tomography using small solid-state dosemeters"],"prefix":"10.1093","volume":"202","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4193-5390","authenticated-orcid":false,"given":"Adnan","family":"Beganovi\u0107","sequence":"first","affiliation":[{"name":"Department of Radiation Protection and Medical Physics, Clinical Center of the University of Sarajevo , Bolni\u010dka 25, Sarajevo 71000,","place":["Bosnia and Herzegovina"]},{"name":"Faculty of Science, University of Sarajevo , Zmaja od Bosne 33\u201335, Sarajevo 71000,","place":["Bosnia and Herzegovina"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lejla M","family":"\u010civa","sequence":"additional","affiliation":[{"name":"Sarajevo School of Science and Technology , Hrasni\u010dka cesta 3a, Ilid\u017ea 71210,","place":["Bosnia and Herzegovina"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mahira","family":"Red\u017ei\u0107","sequence":"additional","affiliation":[{"name":"Department of Radiation Protection and Medical Physics, Clinical Center of the University of Sarajevo , Bolni\u010dka 25, Sarajevo 71000,","place":["Bosnia and Herzegovina"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amra","family":"Skopljak-Beganovi\u0107","sequence":"additional","affiliation":[{"name":"Department of Radiation Protection and Medical Physics, Clinical Center of the University of Sarajevo , Bolni\u010dka 25, Sarajevo 71000,","place":["Bosnia and Herzegovina"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lars","family":"Herrnsdorf","sequence":"additional","affiliation":[{"name":"LH4\u03c0 MicroSense AB , Lovisebergsgatan 10, 462 31 V\u00e4nersborg,","place":["Sweden"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6443-1913","authenticated-orcid":false,"given":"S\u00f6ren","family":"Mattsson","sequence":"additional","affiliation":[{"name":"Medical Radiation Physics, Lund University, Skane University Hospital Malm\u00f6 , SE-205 02 Malm\u00f6,","place":["Sweden"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2026,3,13]]},"reference":[{"key":"2026031302443724500_ref1","volume-title":"Survey of CT practice in the UK.
