ABSTRACT:
In an X-ray CT apparatus for sequentially performing first and second scans of different control parameters by switching the control parameter of at least one of tube voltage and tube current of an X-ray tube on the same slice in a subject, the time interval between the first and second scans is shortened. A scan controller for performing a control on a whole scan starts transmitting the control parameter corresponding to the second scan to an X-ray controller for controlling the tube voltage and the tube current in an X-ray tube during the first scan without waiting for the end of the first scan (S27).
