Evaluation of a Digital Telemammography System: A Model for a Regional System.
Abstract
The research hypothesis being tested is that a telemammography system provides a mechanism for digitizing, transmitting, archiving, and displaying mammograms so that a trained radiologist utilizing grayscale monitors (2k x 2k x 8/12 bits) can interpret the images with an accuracy level sufficient for primary diagnosis. A new metric for measuring the performance of telemammography systems has been developed, throughput/cost ratio. This metric provides a measure for comparing analog to digital mammography systems. This metric has been employed in comparing manufacturing processes, i.e. jobs/sec/cost (1). A ROC curve analysis (2) is utilized to compare the accuracy of interpretation of analog images versus digitized images. The hypothesis is being tested by utilizing a laser film digitizer with a 50-micron pixel size and by performing ROC studies to compare conventional analog screen-film mammography with digitized screen-film mammograms displayed on grayscale workstations (two monitors, each 2k x 2k x 8/12 bits). The wide area network (WAN) being utilized are terrestrial and satellites links. The goal of this study is to determine the requirements to deliver high quality, high resolution mammography images from remote locations that may not have a terrestrial data communications infrastructure available.
