Abstract
The movement of an anti-scatter grid in a radiography apparatus is a continuous curve having point symmetry with respect to the point whose time coordinate is equal to half the exposure time, and for which the space derivative of the time variable has two linear portions which are symmetrical with respect to a symmetry axis passing through the middle of the range of movement of the grid. The grid is moved with a high rate of movement close to the starting position and the end position.
