Abstract
According to one embodiment, an X-ray diagnostic apparatus includes an X-ray source, an X-ray detector, a rotating mechanism, a control unit, and a reconstruction unit. The source irradiates an object with X-rays. The detector outputs projection data by detecting X-rays transmitted through the object. The rotating mechanism rotates the source and the detector around the object. The control unit acquires projection data, while making the rotating mechanism rotate the source and the detector, such that the number of views in a specific view angle range becomes larger than that in other view angle ranges. The reconstruction unit configured to reconstruct an image by using acquired projection data of each view.
