对衍射增强计算机断层技术进行了分析研究,提出了一种新方法.应用该方法只需在摇摆曲线一点处对物体进行360°范围内旋转投影成像,即可获得物体的折射率梯度分布以及吸收系数与散射系数和分布.该方法较以前的方法,大大简化了实验步骤. A new method of diffraction-enhanced computer tomography is proposed, and a new method is proposed.With this method, the object can be rotated and projected 360 ° only at a point of the rocking curve to obtain the gradient distribution and absorption of the object’s refractive index Coefficients and Scattering Coefficients and Distributions This method greatly simplifies the experimental procedure compared to previous methods.
