轴对称体位移场重建方法的研究

The Study of Reconstruction Method on the Displacement Field of the Axisymmetrical Body

从弹性体应变分析的基本理论出发,结合Radon变换卷积重建方法,探讨了反投影重建法引入轴对称连续体应变场的重建问题。文中提出了迭代重建的算法,并给出了计算实例。

The problem on the displacement field reconstruction of the axisymmetrical body with the method of image reconstruction from projection is discussed in this paper.This method's principle is based on the strain analysis theory of elasticity body and is combined with the method of convolution reconstruction on Radon transform. The calculation methods of interative reconstruction is projected. And the example of calculation is gived in the paper.
