三维目标的构造是三维数据可视化的基础，此文首次将CT成象机理引入三维目标重构，提出了断层积分逆问题，并对其可解条件进行了深入的研究。在此基础上形成了一种全新的三维数据构造方法。新方法明显地优于传统的三维重建方法，可以在较厚的断层条件下实现三维目标的准确复原，具有重要的理论和应用价值。

3D object construction is the foundation of 3D data visualization. In this paper, for the first time, the CT imaging mechanism is introduced in to 3D object construction. The inverse problem of the slice integral has been studied and a theory and implementation of 3D object restoration has been proposed. The proposed method has great advantage over the traditional 3D reconstruction theory. It can restore the 3D objects accurately even for the thicker slices. The proposed method is a totally new method and of great theorial and practical sign if icance.
