An object of the present invention is to provide a novel method for generating 3-dimensional radiation images and, more particularly, a method for generating 3-dimensional radiation images capable of aligning completely registered 3-dimensional positions thereof. At least one 2-dimensional radiation image of a subject carried by a radiant ray which has passed through a subject is obtained by irradiating a radiant ray from a plurality of positions, which differ from one another, toward said subject, 2-dimensional pixel data which denotes pixel values at respective points on said 2-dimensional radiation image is obtained by repeatedly scanning an image in a main scanning direction which intersects a sub-scanning direction while sequentially moving in said specified sub-scanning direction on this 2-dimensional radiation image, and 3-dimensional pixel data which denotes the pixel values corresponding to 3-dimensional points inside said subject are obtained based on the 2-dimensional pixel data.
