ON THE CONSIDERATION OF INITIAL PHASE AND INTENSITY PROFILES IN X-RAY PHASE CONTRAST VISUALIZATION

The work is devoted to analytical calculations of the evolution of an intense wave field during 2-D visualization in an X-ray phase contrast experiment to study the internal structure of a homogeneous body.The well-known noniterative algorithm for solving the inverse phase recovery problem was modified by generalizing the initial conditions for the differential transport of intensity equation.An analytical expression for estimating the projected thickness of the studied sample was obtained using the integral Fourier representation of intensities.
