Abstract
There is provided an X-ray image photographing method and an X-ray image photographing apparatus capable of photographing a high resolution phase contrast image and a high resolution absorption contrast image in a short time according to the purpose only by finely adjusting the distance between a specimen and a detector with respect to an X-ray source. The X-ray image photographing method enables photographing of a fine structure with a high space resolution while d/L is sufficiently smaller than 1, when L is a distance from an X-ray sourceto a specimenand d is a distance from the specimento a detector. Further, a distance between a peak position and a valley position of a phase contrast is not less than ⅓Δ and not more than 3Δ, when λ is an average wavelength of the X-ray and Δ is a resolution of the detector
