COMPUTERIZED 3-DIMENSIONAL SEGMENTED HUMAN ANATOMY

Manual segmentation of 129 x-ray CT transverse slices of a living male human has been done and a computerized 3-dimensional volume array mod eling all major internal structures of the body has been created. Each voxel of the volume contains a index number designating it as belongi ng to a given organ or internal structure. The original x-ray CT image s 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-b ased anthropomorphic phantom suitable for many computer-based modeling and simulation calculations.
