This International Standard deals with the definitions, determinations and indication of characteristics of MAMMOGRAPHIC ANTI-SCATTER grids used in diagnostic X-ray imaging equipment, in order to reduce the incidence of SCATTERED RADITION, produced particularly in the body of the PATIENT, upon the IMAGE RECEPTION area and thus to improve the contrast of
the X-RAY PATTERN.
At present only focused ANTI-SCATTER grids are used in mammography. The scope of this standard is therefore restricted to FOCUSED 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 not intended to be applied for the determination of the characteristics of MAMMOGRAPHIC ANTI-SCATTER GRIDS under conditions which can normally be found in installations of X-RAY EQUIPMENT at the USER's site.
