Abstract
Four screen-film systems were evaluated for their imaging properties in mammography [for breast cancer]. Modulation-transfer functions were measured at 40 kVp [kilovolt peak]. Absolute screen-film sensitivities in mR and entrance exposures were measured with W and Mo target tubes. Radiologists [5] viewed radiographs of a phantom containing microgranules of SiC ranging in diameter from 590-120 .mu.m. 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 .mu.m in dimension.This publication has 6 references indexed in Scilit:
