Comparative Study on Phase Imaging of X-Ray and Neutron Sources

After the discovery of X-ray in 1895 the vast majority of radiographs have been taken and interpreted on the basis of absorption contrast of the object. In recent years the possibility of utilizing phase-contrast effect has received considerable attention. This new technique is capable of providing improved information from weakly absorbing samples, together with improved edge enhancement. The method requires use of coherent X-rays to allow wave interferences to occur and manifest itself as contrast formation in the intensity distribution recorded at the detector plane. This paper presents study of phase contrast imaging technique using X-rays & neutron sources.
