Morita, Kyoto, Japan) reduces radiation exposure while maintaining sufficient diagnostic image quality for identifying ectopic eruptions and impacted teeth. Additionally, it was investigated whether a low-noise reconstruction filter (G_101) mitigates image quality degradation in 180\u00b0 scans. Three board-certified oral and maxillofacial radiologists certified by the Japanese Society for Oral and Maxillofacial Radiology visually evaluated clinical images from 12 pediatric patients (aged 6\u201310\u00a0years). The image quality was objectively assessed using phantom-based analyses of the modulation transfer function (MTF), noise power spectrum (NPS), and comprehensive objective image quality calculated from MTF and NPS values. Although 180\u00b0 images showed increased noise and slightly lower visual assessment scores compared with 360\u00b0 images, they remained diagnostically acceptable. In 180\u00b0 reconstructions, the median visual scores with the G_101 filter were slightly higher than those with the standard G_001 filter, with small differences (within approximately 0\u20133 points on a 100-point scale), although the differences were not statistically significant. Interestingly, in approximately 28% of 180 evaluations, 180\u00b0 images scored higher than 360\u00b0 images, likely due to reduced motion artefacts from shorter acquisition. In a previous phantom experiment, the dose area product (DAP) for 360\u00b0 and 180\u00b0 scans was 490\u00a0mGy\u00a0cm\n                    <jats:sup>2<\/jats:sup>\n                    and 249\u00a0mGy\u00a0cm\n                    <jats:sup>2<\/jats:sup>\n                    , respectively, indicating that 180\u00b0 scan reduces radiation exposure while maintaining clinically acceptable image quality. These findings suggest that half-acquisition, when combined with an appropriate reconstruction filter, may offer a practical, low-dose alternative for pediatric dental imaging.\n                  <\/jats:p>","DOI":"10.1007\/s13246-025-01691-2","type":"journal-article","created":{"date-parts":[[2026,1,8]],"date-time":"2026-01-08T16:25:39Z","timestamp":1767889539000},"page":"603-615","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Pediatric dental cone-beam computed tomography using half-acquisition and low-noise reconstruction: visual evaluation of clinical images"],"prefix":"10.1007","volume":"49","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-4516-7370","authenticated-orcid":false,"given":"Misaki","family":"Ito","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9660-8245","authenticated-orcid":false,"given":"Ikuho","family":"Kojima","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masahiro","family":"Iikubo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5761-6434","authenticated-orcid":false,"given":"Shu","family":"Onodera","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masahiro","family":"Sai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masaki","family":"Fujisawa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshiki","family":"Kato","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masaaki","family":"Nakamura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masayuki","family":"Zuguchi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0913-2777","authenticated-orcid":false,"given":"Koichi","family":"Chida","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,1,8]]},"reference":[{"key":"1691_CR1","doi-asserted-by":"publisher","unstructured":"ICRP (2015) Radiological protection in cone beam computed tomography (CBCT).
