ABSTRACT:
A scan control method for an X-ray CT apparatus wherein a subject with a contrast agent injected therein is helically scanned with an X-ray beam and image reconstruction is performed based on projection data obtained through an X-ray detector. The method includes controlling a velocity of a helical scan following motion of the contrast agent in the subject.
