可视化人体的整体坐标系统

Universal Coordinate System of Visual Human Body

可视人数据集是人体解剖结构的基础信息数据集。为了确定人体结构在三维空间中的准确定位以及在不同个体之间便于比较,文中提出和建立了可视化人体的整体坐标系统。以通过耻骨联合上缘中点的水平横切面为标准原点平面,将人体分为上、下部:上部包括头,颈、胸、腹、上臂、前臂等重要部位;下部包括骨盆、下肢和手。人体的整体坐标系可以确定人体重要结构的每一个体元的空间绝对坐标及相对坐标,在图像的分割、匹配、重建中起重要作用。通过坐标系统的变换,人体整体坐标系统可以方便地应用于临床的定位定量诊断,手术导航,放射定位治疗以及人体运动功能等领域的研究。

The visual human data set is the fundamental data set for anatomical information of the human body. In order to locate the human structure in 3-dimensional space precisely and to compare the data set among different individuals conveniently, we suggested and created a universal coordinate system of the human body in which the pubic symphysis horizontal plane was determined as the universal standard original zero plane. The human body can be subdivided into two portions by the original plane. The upper portion includes the head, neck, thorax, abdomen, arm and forearm. While the lower portion includes:the pelvis, lower extremity and hand. The human universal coordinate system can provide a standard geometrical frame for the comparison among different individual data set of the visual human and the precise localization for every voxel in the important structure of the human body. The human universal coordinate system can also be used in the segmentation, matching and reconstruction of images by the coordinate transformation and is of great use in clinical diagnosis, navigation operation, radiation therapy, locomotive function and the human engineering researches.
