Screen speed is an important parameter for patient breast radiation doses and image quality in clinical mammographic examinations.
Replacement of analog systems with digital detectors during the last decades has caused a dramatic drop for film/screen market. On the other hand, there are still many departments using analog systems and they are facing the problem of finding the most suitable combination for their existing films or screens
Speed of the film /screen combinations is mainly determined with X-ray sensitometry which is a relative technique and does not give speed information for the screen alone. This technique is also difficult to implement by many users. It is shown in this work that speed information of the screens can be obtained from the measurement of their quantum detection and light emission efficiencies. Our results can be helpful for the users to set up their optimum film/screen combinations.
