YY/T 0794-2010 Translated English of Chinese Standard. (YYT 0794-2010, YY/T0794-2010, YYT0794-2010): Particular specifications for computed radiography devicehttps://www.chinesestandard.net, 13 août 2020 - 29 pages This standard specifies the terms and definitions, composition, requirements, test methods of computed radiography device. This standard applies to CR. The device uses an image plate that forms a "latent image" after X-ray irradiation; forms a digital X-ray image by scanning the "latent image" on the image plate. CR is used to obtain digital diagnostic images after X-ray device photography, excluding X-ray photography device. |
