When X-rays penetrate the material, the X-ray absorption image is obtained according to the composition of the material. The composition can be measured by using monochromatized X-ray. Using coherent X-ray, the phase contrast image is obtained based on the change in the phase of X rays penetrated through the materials. X-ray phase contrast image was possible only by super research facilities because of the X-ray source needed to be highly controlled. Parametric X-ray was generated from a 80MeV LINAC at LEBRA, Nihon University, and it succeeded in taking a picture of the phase contrast image of the ground specimens of teeth. yNihon University Science Research Subsidy (Sogo 05-029) and the LEBRA Science Frontier Promotionz
