Radiographic contrast improvement by means of slit radiography.
It is generally believed that properly constructed high ratio grids are very efficient in removing radiographic scatter. The authors show that grids inherently transmit substantial amounts of contrast-degrading scatter and suggest a better method of eliminating it. A system of moving paired slits produces radiographic images with higher contrast than do grids at the same tube voltage. The diagnostic implications are discussed.
