Abstract
A Rotating Aperture Wheel (RAW) technology is under development which involves replacing a grid for scatter elimination with an assembly of one fore and two aft lead aperture wheels which are rotated so as to maintain the alignment between the slit or aperture pattern of each. Such a design has the unique feature that its motion can be made independent of the x-ray exposure time and duration allowing for the practical use of a moving slit anti-scatter technique in rapid sequence and dynamic radiographic procedures. The technology is flexible so as to lend itself toward use with varying source-to-image receptor distances (SIDs) such as are involved in fluoroscopy.
