STUDY OF ANTI-SCATTER GRIDS : RADIOGRAPHY WITH HIGH RATIO GRID

Abstract

To improve image quality by removing scattered radiation more perfectly, various anti-scatter devices have been designed and reported. With conventional Bucky's device, when grid's transmission of primary radiation is large and its transmission of scattered radiation is little, we can expect considerable improvement of image quality. A high ratio grid with wood spacer satisfy these conditions. In our hospital, we have changed grid ratio of Bucky's device to 16:1 instead of 10:1, thus enabling a high quality image with little exposure.
