Abstract
Initial measurements of certain display characteristics of a number of cathode ray tubes (CRTs) from different manufacturers are presented. Our aim was to compare the performance of these devices with respect to several critical parameters that affect the display of medical images. We designed a custom CCD imaging system to capture these display characteristics as images. Our CCD imaging system is reasonably portable so that it can travel to a clinical setting. Since a thorough calibration of the CCD imaging system is not completed, the results are reported for comparison purposes only. It was observed that most of the gray scale CRTs that we have studied have similar performances. Results obtained when a color CRT (shadow mask tube) is used to display a gray scale image are also presented. Two sections of the lung region of a digitally acquired computed radiography (CR) PA view chest image were presented on soft-copy and hard-copy displays. Images of these displays were acquired using the CCD imaging system and are presented in this paper.
