1. A medical image diagnostic apparatus, comprising:
- an X-ray tube configured to radiate an X-ray;
a rotor configured to hold the X-ray tube and rotate together with the X-ray tube at least two predetermined, constant rotational speeds, including a first rotation speed used for scanning an object and a second, non-zero rotation speed lower than the first rotation speed; and
processing circuitry configured toacquire information on a waiting time until a time of exposure by the X-ray tube, andcontrol a rotation speed of the rotor during the waiting time in accordance with the acquired information on the waiting time.

Abstract
According to one embodiment, a medical image diagnostic apparatus includes an X-ray tube, a rotor and processing circuitry. The X-ray tube radiates an X-ray. The rotor holds the X-ray tube, and rotates together with the X-ray tube at least any of a first rotation speed used for scanning an object and a second rotation speed lower than the first rotation speed. The processing circuitry acquires information on a waiting time up to timing of exposure by the X-ray tube. The processing circuitry further controls a rotation speed of the rotor during the waiting time in accordance with the information on the waiting time.

12. A medical image diagnostic apparatus, comprising:
-
a rotor configured to hold an X-ray tube and rotate together with the X-ray tube; and processing circuitry configured to control a rotation speed of the rotor in a time period until exposure by the X-ray tube such that the rotor rotates at a first, non-zero rotation speed lower than a second rotation speed required for the exposure by the X-ray tube.
