Scope
YY/T 0480-2021 is the English-translated version of 诊断X射线成像设备 通用及乳腺摄影防散射滤线栅的特性.
YY/T 0480-2021 is the Chinese standard "Diagnostic X-ray imaging equipment-Characteristics of general purpose and mammographic anti-scatter grids". Its scope clause reads: This standard specifies the definition, determination method and representation method of anti-scatter grid characteristics.
This standard applies to anti-scatter grids used in medical diagnostic X-ray imaging equipment. Use an anti-scatter grid to reduce the main The effect of scattered radiation from the patient's body on the image receiving area to improve the contrast of the X-ray pattern.
This standard only deals with linear grids. Currently, only converging grids are used in mammography, so for mammography anti-scatter grids, this standard is limited to Poly grid.
This standard does not apply to acceptance tests. This standard does not address uniformity over the entire area of the grid. This standard applies to the determination of the characteristics of anti-scatter grids under test conditions.
Usually, these test conditions are at the site of the responsible party is not available. Its clauses include terms and definitions.
