Digital acquisition of mammographic images is becoming more diffuse in hospitals, as well as off line digitalization of analogical images to allow use of CAD, filing and statistical tools. Radiologists performance in reading digital images are strictly related to the quality of the images displayed on the monitor. We are investigating how different display devices, influence digital images reading. To reach the goal we are using 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 the GE digital mammograph. The others are a high quality monitor for personal computer and the monitor of a high quality 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 by observing 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.

Abstract
Digital acquisition of mammographic images is becoming more diffuse in hospitals, as well as off line digitalization of analogical images to allow use of CAD, filing and statistical tools. Radiologists performance in reading digital images are strictly related to the quality of the images displayed on the monitor. We are investigating how different display devices, influence digital images reading. To reach the goal we are using 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 the GE digital mammograph. The others are a high quality monitor for personal computer and the monitor of a high quality 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 by observing 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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
