摘　　要：把ＣＴ成像机理引入三维目标重构，提出了基于断层积分求逆的目标复原方法．真实ＣＴ图象实验结果表明，该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，具有重要的理论意义和应用价值．D object construction is the foundation of 3D data visualization.In this paper,the CT imaging mechanism is introduced into 3D object construction,and for the first time,an object restoration method based on the inverse problem of the slice integral has been proposed.It has been proved by the experiment of real CT data that 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 theoretical and practical significance.
