To improve image quality of dual energy tomographic images obtained by helical scan of an X-ray tomographic apparatus having a plurality of X-ray tubes.
An X-ray CT apparatus includes: a bed for placing a subject; a first X-ray generator and a second X-ray generator for generating X-rays; an X-ray detector which is disposed to face the first and second X-ray generators and collects projection data; a rotating part for rotating the first and second X-ray generators with the body axis of the subject as the axis; and a photographing control part which performs helical scan by relatively moving the first and second X-ray generators and the bed while rotating the first and second X-ray generators. The X-ray CT apparatus further includes an X-ray projection data control means which collects X-ray projection data at positions in the same body axis direction and at the same view angle, as respective X-ray projection data based on the X-rays generated from each of the first and second X-ray generators.
