PROBLEM TO BE SOLVED: To provide an X-ray diagnostic apparatus having a noiseless radioscopic image having high resolution and a high image quality. SOLUTION: While irradiating a fan-shaped X-ray beam restricted to a specific width by an X-ray shielding collimator 2 existing in the slice direction, either one of an integral structure of an object 4 or an X-ray source 1 and a multislice detector is moved in the slice direction. X-ray measured data of a specific range in the object slice direction is constituted as an image, and an X-ray transmitted image is displayed. Measuring data with respective slice corresponding detecting element rows are individually stored/recorded. The measuring data is corrected on a measuring position by shifting the measuring view number with respective measuring data groups with a data center position of one or plural specific measuring rows as a reference according to a slice inter-row distance of a multislice detector. A measuring data group after correcting a position is weighed/added to be integrated into one or plural image display measuring data, X-ray radioscopic image reconstituting processing is performed to obtain a radioscopic image, and the image is displayed.
