Thorax of the phantom was first scanned without the use of a contact shield, followed by a scan with a 0.5\u00a0mm lead equivalent out-of-plane shield placed in the localizer but 1\u00a0cm caudally outside the scanned volume. Scans were repeated using the scanner\u2019s organ radiation dose reduction feature. Pitch values 0.35, 0.6, and 1.05 were used. With a pitch of 1.05, the effects of TCM varied between scanners from 4.35% to 356% when scanning toward the caudal end of the scanned volume, when shield was used outside the scanned volume. Also, with some scanners, the use of XCare increased the cumulative tube current.<\/jats:p>","DOI":"10.1093\/rpd\/ncag125","type":"journal-article","created":{"date-parts":[[2026,10,21]],"date-time":"2026-10-21T15:50:33Z","timestamp":1792597833000},"source":"Crossref","is-referenced-by-count":0,"title":["A
