摘要：
An X-ray computed tomography (CT) apparatus according to an embodiments includes collection circuitry, control circuitry and image generation circuitry. The collection circuitry collects a signal derived from X-rays emitted from an X-ray tube and transmitted through a subject. The control circuitry calculates a value of tube current to be supplied to the X-ray tube in a main scan, based on a first image acquired through a reconstruction process using the signal and a first filter, the signal being collected by the collection circuitry in a localizer scan. The image generation circuitry generates a second image as a localizer image through a reconstruction process using the signal and a second filter, the signal being collected by the collection circuitry in the localizer scan.
