This invention provides a radiographic apparatus and method, which can
suitably set a grid in radiography or fluoroscopy and execute fluoroscopy
or radiography of an object under optimum imaging conditions. The
radiographic apparatus includes an X-ray unit (102) which irradiates an
object with radiation (X-rays), a two-dimensional detector (106) which
detects, through a grid, the radiation which has passed through the
object, and a read control unit (107) which acquires an image of the
object from the detected X-rays. The apparatus further includes a user
interface (113) capable of setting imaging conditions such as an X-ray
condition, grid condition, and read condition, a grid switching unit
(105) which selects one of a plurality of grids on the basis of the set
imaging conditions, and a grid stripe reduction unit (109) which reduces
grid stripes generated on the image by the grid.
