Analysis of contrast error mechanism for synchrotron radiation computed-tomography technique
同步辐射计算机断层技术衬度误差机理分析

Based on the unique advantages of high intensity, high resolution and good collimation of synchrotron radiation X-ray, the nondestructive synchrotron radiation computed-tomography technique is widely used in many fields. In this paper, the contrast error of this technique is studied, and four basic error-forms are discussed. The numerical simulation results confirmed the analysis.
