Quantitative Image Quality Analysis of Soft Copy Displays

Abstract

This is a report on work performed in the second year of the project "Quantitative Image Quality Analysis of Soft Copy Displays". The purpose is to make physical image quality measurements on two video display monitors such as are used in digital mammography. There is great interest in optimizing displays for medical imaging, as it is known that displays are the weak link in image quality. In this period we successfully applied the CAMPI (Computer Analysis of Mammography Phantom Images) method to the evaluation of phosphor type of two new monitors. In preliminary results we showed that the P-45 phosphor has advantages over the newly proposed P-104 phosphor. These measurements are a first, and when they are confirmed, will represent a significant contribution to the state of our knowledge regarding soft copy displays.
