A Well Tempered Mammographic Display

Abstract

This proposal addresses the development of a softcopy display for digital mammography that seeks to couple optimally the visual system to the displayed image without excessive human-machine interaction. It also breaks away from two traditional approaches to workstation display design, namely trying to make the softcopy image look like hardcopy and using observer determined window-level and rove-zoom function. The display is calibrated by using both the perceptually standard curve for the monitor and an observer derived display based upon the just noticeable difference in contrast over the intensity range of the monitor. The image is equalized to fit the prescribed intensity range. There is also a built in scanning procedure derived from eye-position observation on skilled mammographers. The calibration procedures are being tested and the scanning procedure is being developed.
