X-RAY CT IMAGING APPARATUS AND X-RAY CT IMAGING METHOD

PROBLEM TO BE SOLVED: To provide an X-ray CT imaging apparatus capable of certainly performing CT imaging of an imaging object region while reducing an exposure dose in a high sensitivity region even when there is the high sensitivity region in the vicinity of an X-ray irradiation region set to the imaging object region, and to provide an imaging method for the same.SOLUTION: In an X-ray imaging apparatus 1 performing CT imaging, a body control unit 60 controls at least one of an X-ray turn face formed by an X-ray cone beam according to a turn of a turn arm 30 and a turn range of the turn arm 30 to reduce X-ray irradiation to a high sensitivity region having high sensitivity related to X-rays in a living body and set with a position inside a region turning during the CT imaging according to a CT imaging region received on an imaging region setting screen.
