Translation of data from porcine models to other biomechanical models requires geometric and inertial properties of the pig head and brain, and a translationally relevant anatomical coordinate system (ACS). In this study, the head and brain mass, center of mass (CoM), and mass moments of inertia (MoI) were characterized, and an ACS was proposed for the pre-adolescent domestic pig. Density-calibrated computed tomography scans were obtained for the heads of eleven Large White\u2009\u00d7\u2009Landrace pigs (18\u201348\u00a0kg) and were segmented. An ACS with a porcine-equivalent Frankfort plane was defined using externally palpable landmarks (right\/left frontal process of the zygomatic bone and zygomatic process of the frontal bone). The head and brain constituted 7.80\u2009\u00b1\u20090.79% and 0.33\u2009\u00b1\u20090.08% of the body mass, respectively. The head and brain CoMs were primarily ventral and caudal to the ACS origin, respectively. The mean head and brain principal MoI (in the ACS with origin at respective CoM) ranged from 61.7 to 109.7\u00a0kg\u00a0cm<jats:sup>2<\/jats:sup>, and 0.2 to 0.6\u00a0kg\u00a0cm<jats:sup>2<\/jats:sup>, respectively. These data may aid the comparison of head and brain kinematics\/kinetics data and the translation between porcine and human injury models.<\/jats:p>","DOI":"10.1007\/s10439-023-03294-y","type":"journal-article","created":{"date-parts":[[2023,6,26]],"date-time":"2023-06-26T15:03:11Z","timestamp":1687791791000},"page":"2544-2553","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Geometric and Inertial Properties of the Pig Head and Brain in an Anatomical Coordinate System"],"prefix":"10.1007","volume":"51","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6488-0391","authenticated-orcid":false,"given":"Nikoo","family":"Soltan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2387-941X","authenticated-orcid":false,"given":"Gunter P.","family":"Siegmund","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5067-0833","authenticated-orcid":false,"given":"Peter A.","family":"Cripton","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0995-1182","authenticated-orcid":false,"given":"Claire F.","family":"Jones","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2023,6,26]]},"reference":[{"key":"3294_CR1","doi-asserted-by":"crossref","unstructured":"Abel, J.
