GOAL
A computer graphics method that permits the reconstruction, visualization and measure of the vertebral deformities of the scoliotic spine is presented.
MATERIALS
Medical imaging techniques utilizing computerized tomography is at the foundation of the reconstruction technique. The studied morphometric parameters are: 1) vertebral body wedging, 2) transverse and spinous process orientation and dimensions and 3) bilateral variation of pedicular dimensions.
RESULTS
The reconstructed specimen showed the usefulness of this technique for visualizing and measuring vertebral deformities. Preliminary results seem to be in agreement with the literature concerning the deformities of scoliotic vertebrae.
CONCLUSION
This tool will be useful in morphometric investigations for the evaluation of the deformations of scoliotic vertebrae.
目标
提出一种计算机图形学方法，该方法可对脊柱侧凸的脊柱椎体畸形进行重建、可视化及测量。
材料
利用计算机断层扫描的医学成像技术是重建技术的基础。所研究的形态测量参数包括：1）椎体楔形变；2）横突与棘突的方向及尺寸；3）椎弓根尺寸的双侧差异。
结果
重建后的标本显示了该技术在可视化及测量椎体畸形方面的实用性。初步结果似乎与有关脊柱侧凸椎体畸形的文献一致。
结论
该工具在形态测量研究中对评估脊柱侧凸椎体的变形将很有用。
