抄録

Since 1895 when the x-ray was discovered, x-ray imaging has been performed with absorption contrast. Somenkov and co-workers have reported that refraction of x-ray improves sharpness of x-ray images by edge effect due to phase contrast. Since this discovery, phase contrast imaging has been studied intensively with coherent x-ray from synchrotron radiation and micro-focus x-ray tubes. We have created a methodology of phase contrast imaging with incoherent x-ray from a practical medical x-ray tube of a small focal spot such as 0.1mm. In this paper, theoretical background of this phase contrast imaging is described for design of digital phase contrast mammography system, and the pixel size for printing of digital mammogram is also discussed.
