X\u2010ray multimeters (XMMs) are compact, solid\u2010state semiconductor dosimeters that have become common for conventional QA measurements due to their ease of use.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Purpose<\/jats:title>\n                    <jats:p>In this investigation, the performance of two XMMs in low\u2010energy x\u2010ray calibration beams was assessed, and the stability of the manufacturer's calibration over time was evaluated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>An RTI Piranha and Radcal Accu\u2010Gold+ with AGMS\u2010DM+ sensor were used to measure air\u2010kerma rates and half\u2010value layers of UW\u2010MO and UW\u2010M series calibration beams. Measurement results were compared to reference values collected with standard instruments. The same measurements were repeated every 3\u20135 months for 2.5 years to evaluate whether the XMMs\u2019 energy response changes over time.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>All air\u2010kerma rate measurements and nearly all half\u2010value layer measurements were within tolerance of the reference measurements. Both XMMs were satisfactorily stable over the course of the study, with all measured air\u2010kerma rates within a 2% range relative to the reference for a specific beam. However, some drift in response was observed, particularly for the RTI Piranha.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Both XMMs met the performance standards provided by their respective manufacturers. An additional calibration would result in increased measurement accuracy for some beam series. One limitation of this study is that the detectors were not subject to more rigorous clinical conditions.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/mp.18106","type":"journal-article","created":{"date-parts":[[2025,9,4]],"date-time":"2025-09-04T05:54:48Z","timestamp":1756965288000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["X\u2010ray multimeter performance under calibration laboratory conditions"],"prefix":"10.1002","volume":"52","author":[{"given":"John T.","family":"Stasko","sequence":"first","affiliation":[{"name":"Department of Medical Physics School of Medicine and Public Health University of Wisconsin\u2010Madison  Madison Wisconsin USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wesley S.","family":"Culberson","sequence":"additional","affiliation":[{"name":"Department of Medical Physics School of Medicine and Public Health University of Wisconsin\u2010Madison  Madison Wisconsin USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,9,3]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/mp.16842"},{"key":"e_1_2_8_3_1","volume-title":"Digital Mammography Quality Control Manual","author":"Berns EA","year":"2018"},{"key":"e_1_2_8_4_1","unstructured":"International Electrotechnical Commission.Medical electrical equipment \u2013 dosimeters with ionization chambers and\/or semiconductor detectors as used in X\u2010ray diagnostic imaging.
