手动分割的129个X射线CT横向切片的一个活的男性人类已经完成，并建立了一个计算机化的三维体积阵列建模的所有主要的内部结构的身体。体积的每个体素包含一个索引号，将其指定为属于给定的器官或内部结构。原始X射线CT图像在512x512矩阵中重建，x，y平面中的分辨率为1 mm。z轴分辨率从颈部到大腿中部为1 cm，从颈部到头顶为0.5 cm。该体积阵列表示人体解剖结构的高分辨率模型，并且可以用作适合于许多基于计算机的建模和模拟计算的基于体素的拟人体模。
Manual segmentation of 129 x-ray CT transverse slices of a living male human has been done and a computerized 3-dimensional volume array modeling all major internal structures of the body has been created. Each voxel of the volume contains a index number designating it as belonging to a given organ or internal structure. The original x-ray CT images were reconstructed in a 512x512 matrix with a resolution of 1 mm in the x,y plane. The z-axis resolution is 1 cm from neck to midthigh and 0.5 cm from neck to crown of the head. This volume array represents a high resolution model of the human anatomy and can serve as a voxel-based anthropomorphic phantom suitable for many computer-based modeling and simulation calculations.
