PROBLEM TO BE SOLVED: To provide an X-ray diagnostic apparatus in which grids easy to produce are used to attain a grid-equivalent interval between absorbing plates required in a high-accuracy detector.SOLUTION: An X-ray diagnostic apparatus 1 includes: an X-ray detector 32 provided with an X-ray tube 21 emitting X-rays from an X-ray focal point F and a plurality of detection elements two-dimensionally allayed in an X-direction and a Y-direction to detect X-rays; and a grid 33 provided on the front surface of the X-ray detector 32 and composed of grid elements 331, 332 each having a plurality of absorbing plates U1, U2 arrayed in the X-direction. The grid 33 has a structure that the absorbing plate U1 arrayed on the grid element 331 shifts in the X-direction in the central projection with respect to the absorbing plate U2 arrayed on the grid element 332, with the X-ray focal point F as a view point. |
