ABSTRACT:
Scatter is reduced in an X-ray system by a relatively large light- or X-radiation-opaque mask rotating on a first axis and carrying smaller, radiation-opaque masks rotating off the first axis. The smaller masks have elongate radiation windows which are held parallel to each other and to a fixed plane through the first axis by translative drive and driven wheels on the larger and smaller masks coupled by a flexible linkage belt.
