Diagnostic X-ray imaging equipment. Characteristics of general purpose and mammographic anti-scatter grids. | Status: Superseded, Withdrawn

1 Scope and object This International Standard deals with the definitions, determination and indication of characteristics of anti-scatter grids used in diagnostic X-ray imaging equipment, in order to reduce the incidence of scattered radiation, produced particularly in the body of the patient, upon the image reception area and thus to improve the contrast of the X-ray pattern. In this standard only linear grids are considered. Since at present only focused grids are used in mammography, this standard is restricted to focused grids for mammographic anti-scatter grids. This standard is not intended to be applied for acceptance tests. This standard does not cover the homogeneity of performance over the area of a grid. This standard is intended to be applied for the demonstration of the characteristics of anti-scatter grids under test conditions. These conditions are not usually available at the user's site.
