In an X-ray CT device, the scan conditions of the device are set, a three-dimensional X-ray passage length model of the body being examined is generated from a scanogram image of the body, the control pattern of the tube current is automatically set on the basis of the scan conditions and the three-dimensional passage length model, and the dose which will be given will be calculated and displayed on the basis of the control pattern of the tube current, and three-dimensional CT value model data of the body generated on the basis of a standard human body. The scanogram image of the body and the control pattern of the tube current are displayed next to each other or overlap to allow an operator to edit the control pattern while viewing the body, so that a suitable tube current can be set.
