Abstract
In an X-ray CT apparatus, a tube current value calculation unit calculates a tube current value of an X-ray tube based on a successive approximation process condition and based on an input scanning condition and/or a reconstruction condition. A scanning control unit performs scanning based on the calculated tube current value of the X-ray tub, and an image reconstruction unit reconstructs a tomographic image of an object, in accordance with the selected successive approximation process condition and the reconstruction condition. The tomographic image is reconstructed from an amount of transmitted X-rays detected by an X-ray detector after being emitted from an X-ray source to the object, in accordance with the calculated tube current value of the X-ray tube, and being transmitted through the object.
