Abstract

The AT&T CommView® image management and communication system (IMACS) at Georgetown University supports multiple work stations for diagnosis, review, and research. Consistancy of the perceived brightness of displayed images throughout the network in the hospital is a critical issue. A simple method has been developed to set and track the brightness of cathod ray tuned used to display radiological images. A computer generated test image (SMPTE) is used. This consists of 11 brightness patches equally spaced over the dynamic range of CRT intensity driving levels. This test image is displayed and viewed in the same manner as patient images. An inexpensive hand-held photometer calibrated in ft-Lamberts is used to measure the brightness patches of the test images.
