Paper Abstract

By the middle of 1994, most of the radiology diagnoses at Madigan Army Medical Center will be performed on diagnostic workstations rather than from hardcopy films. Consistent, high- quality images must be produced by the different monitors to help support accurate diagnoses and consultation. We have applied several quality control tests to various types of monitors attached to a clinically-functioning medical diagnostic imaging support (MDIS or PACS) system at Madigan to ensure the high quality of diagnostic image display. Many characteristics of a monitor can degrade over time, including luminance, spatial uniformity, and spatial resolution. Tests to measure these characteristics are explained and results are shown. A photometer and the SMPTE test pattern are used in many of the tests. The results of different monitors on the same workstation are compared as well as the results from the same monitor over time. Technicians from the PACS vendor adjust the maximum brightness of the monitors periodically at Madigan so that they meet the specification. Our data shows that this adjustment alone is not sufficient to ensure that the other characteristics of a monitor are within acceptable values.
