脑血管变异的知识在教育、培训、诊断和治疗中是必不可少的。目前的血管系统，特别是血管变异的表现方式是不够的。我们的目的是构建一个三维（3D）交互式地图集的脑动脉变异沿着探索工具，使调查人员只需点击几下，以更好，更快地了解变异及其空间关系。之前创建的脑动脉系统的3D模型，完全标记了名称和直径，用作参考。由于有关血管变异性的大量材料不完整且未完全记录，因此我们的方法基于现有知识在3D中合成变异。使用专用血管编辑器根据文献创建变体，并嵌入参考模型中。创建60个3D变体和分支模式，包括颈内动脉、大脑中动脉、大脑前动脉、大脑后动脉、椎动脉和基底动脉以及Willis环。列出了其流行率。开发图谱以单独探索变体或嵌入参考脉管系统中。提供变体和参考脉管系统的实时交互式操作（旋转/缩放/平移/查看）。该图谱有助于研究人员轻松熟悉变体并快速探索它们。它有助于呈现血管变体并理解其单独或嵌入周围参考血管系统的空间关系。这对医学生、教育工作者准备教学材料和临床医生进行扫描解释是有用的。它可以很容易地通过额外的变体实例、新变体、分支模式和支持文本材料进行扩展。
The knowledge of cerebrovascular variants is essential in education, training, diagnosis and treatment. The current way of presentation of vasculature and, particularly, vascular variants is insufficient. Our purpose is to construct a three-dimensional (3D) interactive atlas of cerebral arterial variants along with exploration tools allowing the investigator just with a few clicks to better and faster understand the variants and their spatial relationships. A 3D model of the cerebral arterial system created earlier, fully labeled with names and diameters, is used as a reference. As the vast material about vascular variability is incomplete and not fully documented, our approach synthesizes variants in 3D based on existing knowledge. The variants are created from literature using a dedicated vascular editor and embedded into the reference model. Sixty 3D variants and branching patterns are created including the internal carotid, middle cerebral, anterior cerebral, posterior cerebral, vertebral and basilar arteries, and circle of Willis. Their prevalence rates are given. The atlas is developed to explore the variants individually or embedded into the reference vasculature. Real-time interactive manipulation of variants and reference vasculature (rotate/zoom/pan/view) is provided. This atlas facilitates the investigator to easily get familiarized with the variants and rapidly explore them. It aids in presentation of vascular variants and understanding their spatial relationships either individually or embedded into the surrounding reference cerebrovasculature. It is useful for medical students, educators to prepare teaching materials, and clinicians for scan interpretation. It is easily extensible with additional variant instances, new variants, branching patterns, and supporting textual materials.
