Abstract:
1. A radiography apparatus comprising: a radiation source that outputs radiation to a subject; a detection means that detects the radiation that has passed through the subject; an image obtainment means that moves, relative to the detection means, the radiation source in a movement range that is calculated based on a desired slice angle with respect to a predetermined base point on a base plane that defines a range of obtaining a slice image of the subject, thereby moving the radiation source to a plurality of positions, and that obtains a plurality of radiographic images of the subject corresponding to the plurality of positions by irradiating the subject with radiation from the plurality of positions; an image reconstruction means that reconstructs the slice image from the plurality of radiographic images; and a selection means that selects, based on a distance from a detection surface of the detection means to a slice plane on which the slice image is generated and the desired slice angle, radiographic images to be used to reconstruct the slice image.
