Several biomechanical simulation models of parturition have been proposed to investigate birth, but many do not include the uterus. Additionally, most solid models rely on segmenting anatomical structures from clinical images to generate patient geometry, which can be time-consuming. This work presents two new parametric solid modeling methods for generating patient-specific, at-term uterine three-dimensional geometry. Building from an established method of modeling the sagittal uterine shape, this work improves the uterine coronal shape, especially where the fetal head joins the lower uterine wall. Solid models of the uterus and cervix were built from five at-term patients' magnetic resonance imaging (MRI) sets. Using anatomy measurements from MRI-segmented models, two parametric models were created\u2014one that employs an averaged coronal uterine shape and one with multiple axial measurements of the coronal uterus. Through finite element analysis, the two new parametric methods were compared to the MRI-segmented high-fidelity method and a previously published elliptical low-fidelity method. A clear improvement in the at-term uterine shape was found using the two new parametric methods, and agreement in principal Lagrange strain directions was observed across all modeling methods. These methods provide an effective and efficient way to generate three-dimensional solid models of patient-specific maternal uterine anatomy, advancing possibilities for future research in computational birthing biomechanics.<\/jats:p>","DOI":"10.1115\/1.4065109","type":"journal-article","created":{"date-parts":[[2024,3,16]],"date-time":"2024-03-16T11:31:26Z","timestamp":1710588686000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":5,"title":["Parametric Solid Models of the At-Term Uterus From Magnetic Resonance Images"],"prefix":"10.1115","volume":"146","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6384-0777","authenticated-orcid":false,"given":"Erin M.","family":"Louwagie","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, Columbia University, New York, NY 10027"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Divya","family":"Rajasekharan","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Columbia University, New York, NY 10027"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arielle","family":"Feder","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Columbia University, New York, NY 10027"},{"id":[{"id":"https:\/\/ror.org\/04mhzgx49","id-type":"ROR","asserted-by":"publisher"}],"name":"Tel Aviv University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6925-0217","authenticated-orcid":false,"given":"Shuyang","family":"Fang","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Columbia University, New York, NY 10027"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chia-Ling","family":"Nhan-Chang","sequence":"additional","affiliation":[{"name":"Department of Obstetrics & Gynecology, Irving Medical Center, Columbia University, New York, NY 10032"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mirella","family":"Mourad","sequence":"additional","affiliation":[{"name":"Department of Obstetrics & Gynecology, Columbia University, Irving Medical Center , New York, NY 10032"},{"id":[{"id":"https:\/\/ror.org\/01esghr10","id-type":"ROR","asserted-by":"publisher"}],"name":"Columbia University Irving Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kristin M.","family":"Myers","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Columbia University, New York, NY 10027"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"33","published-online":{"date-parts":[[2024,4,8]]},"reference":[{"key":"2024040813540701700_bib1","article-title":"Births: Provisional Data for 2021","year":"2022"},{"issue":"2","key":"2024040813540701700_bib2","doi-asserted-by":"crossref","first-page":"197","DOI":"10.1001\/jama.2014.14774","article-title":"Variation in and Factors Associated With Use of Episiotomy","volume":"313","year":"2015","journal-title":"J.
