| Abstract: | Objective To investigate and compare the image quality of phase-contrast mammography and full-field digital mammography.Methods ACR RMI-156 phantom was selected and were exposured at PCM and FFDM.The exposured condition was the same in two groups except in automaticexposure.Three radiologisits evaluate the phantom X-ray images which were printed to film respectively.The method of evaluating RMI-156 was scoring(according to minute structure inside phantom).Compare the difference of scoring between the PCM an... |
