Abstract：
The presentation of cortical arteries is challenging, as most of their course is hidden in the depth of the sulci. Despite that, demonstrating the arteries on the cortical surface is a standard way of their presentation. To keep advantages of surface presentation while lessening its limitation, we propose a novel context-related method of cerebrovasculature presentation by cortical openings consisting in the removal of a selected region from the cortical mantle and exposing underlying structures. We also introduce a reverse than standard vessel-to-context mapping from a gyrus/lobule to vessels supplying it.The method has the following steps: define a cortical opening, develop a tool to perform them, create cortical openings for gyri and lobules with underlying white matter and intracranial arteries, generate labeled and parcellated images for the created openings, and integrate the cortical opening images with the NOWinBRAIN public repository of 8600 3D neuroimages.The cortical openings are created for 64 gyri and six lobules for the left and right cerebral hemispheres resulting in 210 images arranged in triples as spatially corresponding non-parcellated and unlabeled, parcellated by color and unlabeled, and parcellated and labeled images.The cortical opening approach, generally, increases vessel exposure in a higher number of depicted branches, revealing arteries otherwise hidden deep in sulci, a more complete vessel course, and a lower number of required views.The gyrus/lobule-to-arteries mapping facilitates exploration of a studied region, encapsulates all local arteries, and reduces vascular complexity by decomposing the entire vascular system into smaller sets involved in the studied region.
摘要：
皮质动脉的呈现具有挑战性，因为他们的大部分课程是隐藏在深沟。尽管如此,展示皮质表面的动脉是它们呈现的标准方式。为了保持表面呈现的优势，同时减少其局限性，我们提出了一种新的上下文相关的方法，通过皮质开口来呈现脑血管系统，包括从皮质套中去除选定的区域并暴露底层结构。我们还引入了从回/小叶到提供回血管的标准血管到上下文映射的反向映射。该方法具有以下步骤:定义皮质开口,开发一个工具来执行它们，为回旋和小叶创建皮质开口，并带有潜在的白质和颅内动脉，为创建的开口生成标记和分割的图像，并将皮质开口图像与NOWinBRAIN公共存储库的8600个3D神经图像集成在一起。为左右大脑半球的64个回旋和六个小叶创建皮质开口，从而产生210个图像，这些图像在空间上对应于非分割和未标记的三元组排列，按颜色和无标签划分，以及分割和标记的图像。皮质开放方法，一般来说,增加血管暴露在更多数量的描绘分支，露出深藏在沟中的动脉，更完整的船只航线，和较少数量的所需意见。回回/小叶到动脉的测绘有助于探索研究区域，封装所有局部动脉，并通过将整个血管系统分解为涉及研究区域的较小集合来降低血管复杂性。
