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.
