<p>A digital radiation image imaging system to detect an edge-emphasized image highly accurately, and to output the detected edge-emphasized image without deteriorating the image is provided. Under the assumption that D (µm) represents a focal point diameter of X-ray tube, S (µm) represents a minimum control unit of a digital detector, A (µm) represents a minimum control unit of an image output apparatus, R1 (m) represents a distance from a focal point of X-ray tube to a subject, R2 (m) represents a distance from a subject to the digital detector, magnifying power M equals (R1 + R2) / R1, and E represents an edge emphasis width caused by X-ray refraction, S > A and D ‰¥ (S - E) / (M - 1) are caused to hold, and the minimum control unit of the digital detector S and an aggregate of n pieces of minimum control units of the image output apparatus are caused to correspond as data to be reproduced and outputted.</p> |
