摘要： An X-ray CT apparatus includes a specifying unit, a setting unit, a controller, and a reconstruction unit. The specifying unit refers to exposure dose information to specify a high exposure area in an imaging area in a subject. The setting unit sets a scan condition under which a cross section of the imaging area can be imaged and under which X-rays are not directly applied to the high exposure area or another scan condition under which a cross section of the imaging area can be imaged and under which an X-ray radiation dose directly applied to the high exposure area is reduced relative to an area other than the high exposure area. The controller collects data of X-rays applied from an X-ray tube and detected by an X-ray detector under the set scan condition. The reconstruction unit reconstructs a tomographic image using the collected data of X-rays.
