X Ray Phase Contrast Imaging for the Extreme Low Density or Weak Absorption Materials

Abstract:

Article Preview

In order to get better images from the extreme low density or weak absorption materials, a new modulation transfer function model is established for the X ray phase contrast imaging. Then the parameter effects of ray source size are elaborated on the basis of the partially coherent optical theory. From the simulation and calculation, the proposal and parameter optimization are revealed according to the actual materials experiment conditions.
