Abstract
A digital radiation image radiographing system includes an X-ray tube to irradiate a radiographic subject with X-rays and a digital detector to detect X-rays having passed through the radiographic subject, and performs a phase contrast radiography. The system satisfies a formula (D≧(S−E)/(M−)), in which D (μm) represents the focal size of the X-ray tube, S (μm) represents the minimum control unit of the digital detector, R(m) represents a distance from the focus point of the X-ray tube to the radiographic subject, R(m) represents a distance from the radiographic subject to the digital detector, M represents an enlargement ratio (M=(R+R)/R), and E represents an edge enhancement width according to X-ray refraction.
