Abstract

A radiographic diagnostic apparatus including an X-ray tube for generating X-ray radiation, a line slit for shaping the X-ray radiation into a fan beam, a linear X-ray sensor array for detecting the X-ray radiation, and apparatus for driving the components is provided. The focal spot of the X-ray tube and the line slit are disposed on a straight line that connects between a specified fixed point and the center of the linear sensor array of a line extending therefrom. The X-ray tube, the line slit and the linear X-ray sensor array are driven together in a direction perpendicular to the direction of alignment of the linear X-ray sensor array so as to scan an object and thereby produce a radiographic image of the object.
