Diagnostic X-ray imaging equipment. Characteristics of general purpose and mammographic anti-scatter grids (IEC 60627:2013)
This International Standard is applicable to ANTI-SCATTER GRIDS used in medical diagnostic Xray imaging equipment. ANTI-SCATTER GRIDS are used 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. This International Standard specifies the definitions, determination and indication of characteristics of ANTI-SCATTER GRIDS. 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 where MAMMOGRAPHIC ANTI-SCATTER GRIDS are concerned. 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 determination of the characteristics of ANTISCATTER GRIDS under test conditions. These conditions are not usually available at the site of the RESPONSIBLE ORGANIZATION.
