To develop a robust and accurate multi-parameter assessment framework for adolescent idiopathic scoliosis based on spinal x-ray images, overcoming the limitations of traditional Cobb angle (CA)-based evaluation.\n Approach<\/jats:italic>\n . We proposed a dual-view labeling protocol and employed a Residual U-Net architecture to segment vertebral bodies in 700 paired anteroposterior and lateral x-rays. A novel Local Sine-based Spinal Projection Model was introduced to calculate vertebral inclination angles and derive consecutive CAs. Additional spinal parameters, including coronal balance (T1PL-CSVL), force line (FL), and FL balance, were computed to enable comprehensive spinal evaluation.\n Main results<\/jats:italic>\n . The proposed method achieved a vertebral segmentation Dice coefficient of 94.7%. The mean absolute error of the CA was\n \n \n \n <\/jats:tex-math>\n \n \n \n 2.71<\/mml:mn>\n \u2218<\/mml:mo>\n <\/mml:msup>\n <\/mml:mrow>\n <\/mml:math>\n <\/jats:inline-formula>\n , outperforming the minimum bounding rectangle method (\n \n \n \n <\/jats:tex-math>\n \n \n \n 3.46<\/mml:mn>\n \u2218<\/mml:mo>\n <\/mml:msup>\n <\/mml:mrow>\n <\/mml:math>\n <\/jats:inline-formula>\n ) and novice manual measurements (\n \n \n \n <\/jats:tex-math>\n \n \n \n 5.40<\/mml:mn>\n \u2218<\/mml:mo>\n <\/mml:msup>\n <\/mml:mrow>\n <\/mml:math>\n <\/jats:inline-formula>\n ), with an intraclass correlation coefficient of 0.958. In diagnostic grading, 120 out of 142 patients were correctly classified (84.5% success rate). Longitudinal follow-up demonstrated accurate tracking of structural improvements and coronal balance recovery following conservative treatment.\n Significance<\/jats:italic>\n . This approach enables automatic, precise, and comprehensive scoliosis evaluation by integrating fine-grained segmentation with geometric modeling of spinal curvature. The proposed method improves spinal assessment accuracy and facilitates longitudinal scoliosis monitoring, offering substantial clinical utility and impact in computer-aided orthopedic diagnosis.\n <\/jats:p>","DOI":"10.1088\/1361-6560\/ae8ca3","type":"journal-article","created":{"date-parts":[[2026,7,17]],"date-time":"2026-07-17T22:55:45Z","timestamp":1784328945000},"page":"155009","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Multi-parameter scoliosis evaluation from dual-view x-rays via a local sine-based projection model"],"prefix":"10.1088","volume":"71","author":[{"given":"Xianbin","family":"Wang","sequence":"first","affiliation":[{"name":"The First Affiliated Hospital of Heilongjiang University of Traditional Chinese Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guobao","family":"Ma","sequence":"additional","affiliation":[{"name":"Foshan University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenrui","family":"Wu","sequence":"additional","affiliation":[{"name":"Foshan University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9862-3657","authenticated-orcid":true,"given":"Wenzheng","family":"Ding","sequence":"additional","affiliation":[{"name":"Foshan University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Honglian","family":"Xiong","sequence":"additional","affiliation":[{"name":"Foshan University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mingyi","family":"Wang","sequence":"additional","affiliation":[{"name":"Foshan University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2026,8,3]]},"reference":[{"key":"pmbae8ca3bib1","doi-asserted-by":"publisher","first-page":"1227","DOI":"10.1302\/0301-620X.98B9.37273","type":"journal-article","article-title":"Coronal imbalance in degenerative lumbar scoliosis: prevalence and influence on surgical decision-making for spinal osteotomy","volume":"98","author":"Bao","year":"2016","journal-title":"Bone Joint J."},{"key":"pmbae8ca3bib2","doi-asserted-by":"publisher","first-page":"543","DOI":"10.1053\/crad.2001.0909","type":"journal-article","article-title":"Imaging in scoliosis: what, why and how?","volume":"57","author":"Cassar-Pullicino","year":"2002","journal-title":"Clin.
