Four screen-film systems were evaluated for their imaging properties in mammography, Modulation-transfer functions were measured at 40 kVp. Absolute screen-film sensitivities in mR and entrance exposures were measured with tungsten and molybdenum target tubes. Five radiologists viewed radiographs of a phantom containing microgranules of SiC ranging in diameter from 590 to 120 micrometer. The Rarex-B screen--composed of yttrium oxysulfide--performed best, allowing phantom radiographs at 185 mR with image quality sufficient to demonstrate microgranules greater than 330 micrometer in dimension.
对四种屏-片系统在乳腺摄影中的成像特性进行了评估，在40 kVp下测量调制传递函数。使用钨靶和钼靶管测量了以毫伦琴（mR）和入射曝光表示的绝对屏-片灵敏度。五位放射科医生查看了含有直径范围从590至120微米碳化硅微粒的体模的射线照片。由硫氧化钇组成的Rarex-B屏表现最佳，在185 mR时即可获得体模射线照片，其图像质量足以显示尺寸大于330微米的微粒。
