Paper Abstract

As presentation of medical radiographic images on soft-copy displays (cathode ray tubes) becomes increasingly prevalent in electronic radiography, methods of quality assurance must be developed to ensure that radiologists can effectively transfer film-based reading skills. Luminance measurements provide the basis for evaluating the state of soft-copy displays. An integrated approach has been implemented at Mallinckrodt Institute of Radiology (MIR) which facilitates measurement of geographically distributed soft-copy displays with centralized data logging, performance tracking and calibration. MIR''s central radiology image manager (RIM) exercises the display station which drives the monitor, harvests the measurement data, stores the results and submits the resulting data for additional processing. The luminance measurements are collected by a small, portable photometric instrument designed at MIR that includes a serial port which is accessed via local area terminal service (LAT) supported by the RIM. The design details of the photometric instrument and example luminance characteristics of several soft-copy displays used at the Mallinckrodt Institute are presented in this paper.
