摘要：
PROBLEM TO BE SOLVED: To provide an X-ray inspection device and an X-ray inspection method capable of certainly detecting a soft and small abnormal tissue with a small amount of exposure, in a medical diagnosis field. SOLUTION: A fan-beam-like X-ray is emitted into a photographic subject, a permeation X-ray image which permeates the photographic subject and comes into an X-ray detector 13 is detected by the X-ray detector 13, and the X-ray image is processed and reconstructed as a refraction X-ray image. Thus, an abnormality of a soft tissue or void in the photographic subject that is hardly detected in difference by X-ray photographing by the permeation X-ray image can be obtained as an image output.
