Objective    To establish digitized visible model of hip joint and study its CT 3D imagings

and to provide morphological data for image diagnosis and hip surgery planning.     Methods    (1)Twenty cases of hip pain were scanned with helical CT and the images were rebuilt with bone three-dimensional reconstruction in CT workstation. (2)The bones

muscles

nerves and vessels were drew accurately in the hip cross-sectional images of the first female Chinese visible human dataset

and the dimensional computer reconstructions of the hip by surface rendering were got on a SGI workstation.     Results    (1)The three-dimensional reconstruction images of helical CT can reveal the spatial relation adjacent to the bones distinctly and perfectly. (2)The visualized reconstructions of hip

including bones and soft tissues

can be presented individually or jointly.     Conclusion    Hip joint CT three-dimensional reconstruction and the digitized visible model can display the stereo and spatial relations completely and accurately.
