The scanning grid: a novel and effective bucky movement.
A grid consisting of a focused array of radiopaque strips has been constructed. No interspace material is employed, and, during an exposure, the arrangement moves so that the grid strips remain focused and a uniform film density is obtained. Preliminary measurements and radiographs of patients indicate that such a device is a practical and effective method of suppressing scatter.
