However, it is unclear that external detectors could evaluate the KAP meter accuracy under the TG\u2010125 geometry.<\/jats:p>\n <\/jats:sec>\n \n Purpose<\/jats:title>\n This study investigated whether the reference air kerma rate () values of the KAP meter increase with increasing field of view (FOV) and whether an external ionization chamber and solid\u2010state detector (SSD) could be used to evaluate KAP meter accuracy in TG\u2010125 geometry.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n An ionization chamber and three different SSDs (Radcal AGMS\u2010DM+, Raysafe X2 R\/F sensor, and RTI Dose Probe) were placed at the patient entrance reference point in a C\u2010arm fluoroscopic system, and measurements were taken at FOV settings of 18, 25, 34, and 42 cm using both the TG\u2010190 and TG\u2010125 geometries. The , incident air kerma rate (, and entrance surface air kerma rate ( values were recorded simultaneously and compared. The measurement data were used to calculate the backscatter factor.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n The increased linearly with the relative X\u2010ray output, and their slopes significantly increased with the FOV. The values of the ionization chamber increased with the FOV; however, the values of the ionization chamber, and values of the SSDs were not dependent on the FOV and were nearly identical to each other. Although the backscatter factor for the KAP meter and ionization chamber increased with the FOV, the backscatter for the SSDs were close to unity in all FOVs and no significant difference was observed.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n The results indicated that the values of KAP meter were increased with the FOV. Furthermore, the SSDs could be utilized to evaluate the KAP meter accuracy in TG\u2010125 geometry.<\/jats:p>\n <\/jats:sec>","DOI":"10.1002\/acm2.70281","type":"journal-article","created":{"date-parts":[[2025,10,9]],"date-time":"2025-10-09T12:32:08Z","timestamp":1760013128000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Investigating the use of ionization chamber and solid\u2010state detectors to evaluate kerma\u2010area product meter accuracy under TG\u2010125 geometry across variable field of views"],"prefix":"10.1002","volume":"26","author":[{"given":"Atsushi","family":"Fukuda","sequence":"first","affiliation":[{"name":"Department of Radiological Sciences School of Health Sciences Fukushima Medical University Fukushima Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7126-3989","authenticated-orcid":false,"given":"Pei\u2010Jan Paul","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Radiology Virginia Commonwealth University Health System Richmond Virginia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,10,9]]},"reference":[{"key":"e_1_2_10_2_1","volume-title":"Amendment 2\u2010Medical Electrical Equipment\u2010Part 2\u201343: Particular Requirements for the Basic Safety and Essential Performance of X\u2010Ray Equipment for Interventional Procedures","author":"International Electrotechnical Commission (IEC)","year":"2019"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcin.2012.10.016"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1177\/0284185116658682"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvir.2022.08.023"},{"key":"e_1_2_10_6_1","volume-title":"IEC 60580:2019.
