Digital acquisition of mammographic images is becoming more diffuse in hospitals, and so is off line digitalization of analogic images to allow use of CAD, filing and statistical tools. Radiologists performance in reading digital images is strictly related to the quality of the images displayed on the monitor. We investigated how different display devices, influence digital images reading. For our study we used phantoms for quality controls in mammography. Three different monitors are considered. The first one is the high resolution CRT display used as diagnostic monitor for a GE digital mammograph. The others are a high quality monitor for desktop personal computer and the display of a top of the line notebook. The phantoms used are the CDMAM 3.2 (a contrast-detail phantom) and the RMI 156 (which contains test objects that represent malignancies and small breast structures). Their images were acquired by the digital mammograph and were then analyzed by two expert radiologists who observed them on the different display devices, adopting the same procedure. The results about the reading of the phantoms and the interpretation of the images with different monitors are presented here.
