摘要：
The basic imaging characteristics of a new mammographic screen-film combination have been experimentally determined. These characteristics include absolutely calibrated sensitometry, modulation transfer functions, noise power spectra, noise equivalent quanta, and detective quantum efficiency. Specific image quality advantages of this new system are discussed, including a substantial reduction in film noise, and comparisons are made with an established mammography system.
