Abstract
Two 30 cm diameter steel drums with four facets rotating at 1800 RPM have produced high-quality digital-subtraction radiographs by alternately blocking and transmitting dual-energy synchrotron X-ray beams. An eight times faster system with 16.5 cm diameter tenfaceted tin-plated aluminum drums rotating at 5760 RPM is presently under construction.
