The oVert (openVertebrate) Thematic Collection Network (TCN) will generate and serve high-resolution digital three-dimensional (3D) data for internal anatomy across vertebrate diversity. Via a network of digitization centers across the US, more than 20,000 fluid-preserved specimens representing over 80% of the living genera of vertebrates will be CT-scanned. This will provide broad coverage for exploration and research on all major groups of vertebrates. Contrast-enhanced scans will be generated that reveal soft tissues and organs. This collection of digital imagery and three-dimensional volumes will be open for exploration, download, and use to address questions related to the discovery of new species, documenting patterns of anatomical diversity and growth, and testing hypotheses of function and evolution. The resource will provide unprecedented global access to valuable specimens in US museum collections and will develop best practices and guidelines for high-throughput CT-scanning, including efficient workflows, preferred resolutions, and archival formats that optimize the variety of downstream applications. Museum specialists will be trained on the generation, curation, and distribution of 3D data, researchers in using 3D anatomical data, and high school and undergraduate students in the tools for creating 3D anatomical models. To drive the use of these digital specimens by K-12 STEM educators, teacher-driven workshops that generate freely available lesson plans focused on specific science standards that are based on digital and printed 3D models of specimens in US museum collections.Data generated by oVert will serve as a catalyst for diverse research projects focused on understanding the vertebrate morphological diversity and will dramatically increase the accessibility of specimens housed in US scientific collections. These anatomical phenotypes represent a common currency that facilitates integration across the fields of taxonomy, evolution, developmental biology, comparative physiology, functional anatomy, paleontology, and ecology. The x-ray computed tomography (CT) scanning gemerates high-resolution digital anatomical data, represented as both 2D image stacks and 3D volumes and surfaces. With these 3D digital specimens, US and international research communities will be able to (1) diagnose, describe, and infer patterns of relationships among both living and extinct vertebrates, (2) test hypotheses of morphological evolution such as patterns of disparity, modularity, and phenotype-environment correlations, (3) develop structure-function models for testing hypotheses about morphological adaptations related to, e.g., feeding and locomotion, and (4) explore relationships between brain and nervous system anatomy and both sensory and musculoskeletal function. The 3D data will be distributed globally through MorphoSource, an on-line data repository for 3D biological specimen data, which will capture standardized metadata, ingest legacy data from previous and existing projects, and will supply media information to data aggregators including iDigBio (www.idigbio.org). Training workshops, both on-site at participating institutions and national society meetings of scientists and educators are planned to foster innovation and capabilities for users of 3D image data.

公开的（开放膜）主题收集网络（TCN）将生成并为跨脊椎动物多样性的内部解剖结构生成并提供高分辨率数字三维（3D）数据。 通过整个美国的数字化中心网络，将ct扫描占20,000多种占脊椎动物生命属的水平超过80％的标本。 这将为所有主要脊椎动物群体探索和研究提供广泛的覆盖范围。 将产生对比增强的扫描，以显示软组织和器官。 该数字图像和三维卷的集合将开放，用于探索，下载和用于解决与发现新物种有关的问题，记录解剖学多样性和增长的模式以及测试功能和进化的假设。 该资源将在美国博物馆收藏中提供前所未有的全球对有价值标本的访问，并将为高通量CT扫描的最佳实践和准则提供最佳实践和准则，包括高效的工作流程，首选分辨率和档案格式，以优化各种下游应用程序。 博物馆专家将接受3D数据的一代，策划和分布的培训，研究人员使用3D解剖学数据以及高中和本科生，用于创建3D解剖模型的工具。 为了推动K-12 STEM教育工作者使用这些数字标本的使用，以教师为驱动的研讨会，这些研讨会可免费提供基于美国博物馆集合中的数字和印刷3D标本的特定科学标准。这些解剖表型代表了一种共同的货币，可促进分类，进化，发育生物学，比较生理学，功能解剖学，古生物学和生态学领域的整合。 X射线计算机断层扫描（CT）扫描宝石可高分辨率数字解剖数据，以2D图像堆栈和3D体积和表面表示。 借助这些3D数字标本，美国和国际研究社区将能够（1）诊断，描述和推断生命和灭绝脊椎动物之间关系模式的模式，（2）测试形态进化的假设，例如，差异，模块化，模块化和表型 - 环境互相关的模型，（3）对结构互动的模型，（3）与测试相关的模型。运动和（4）探索大脑与神经系统解剖结构以及感觉和肌肉骨骼功能之间的关系。 3D数据将通过Morphosource在全球分布，Morphosource是3D生物标本数据的在线数据存储库，该数据将捕获标准化的元数据，以前和现有项目的摄入遗产数据，并将向包括IDIGBIO（www.idigbio.org）在内的数据聚合器提供媒体信息。 培训讲习班，即参与机构的现场和科学家和教育工作者的国家社会会议，以促进3D图像数据用户的创新和能力。
