Patent ID: 7257190

Claim:
A radiographic device comprising: a radiation source which generates radiation; a detector which detects radiation from said radiation source on a two-dimensional plane and outputs image data; an imaging control unit configured to perform radiography of a subject to be examined while rotating said radiation source and said detector relative to the subject; a setting unit which sets a rotational position; a selection unit configured to select a first resolution in case of the set rotational position and select a second resolution lower than the first resolution in case of rotational positions except for the set rotational position, in the radiography in the relative rotation; a speed control unit configured to switch a speed of the relative rotation to a first speed in case of the set rotational position and switch a speed of the relative rotation to a second speed higher than the first speed in case of rotational positions except for the set rotational positions; and a storage unit configured to store image data corresponding to a resolution selected by said selection unit on the basis of the image data from said detector.
