Abstract
A radiographic image diagnostic apparatus according to embodiments includes an X-ray tube, a holding member, and coil control circuitry. The X-ray tube includes: a cathode that emits electrons; coils that generate electromagnetic force; and an anode that rotates about a rotation axis in response to the electromagnetic force and to generate an X-ray by receiving the electrons. The holding member holds the X-ray tube so that the X-ray tube is movable. The coil control circuitry controls a current to be supplied to the coils based on at least one of a position of the X-ray tube, a direction of the X-ray tube, or a velocity of the X-ray tube.
