Abstract

The purpose of this paper is to report on the experience we have gained with regard to image quality assurance (QA) in a clinical teleradiology practice between a central university hub and multiple very remote rural spokes in a two state area. Identical standard SMPTE test pattern images were supplied to each remote site which digitized and transmitted them at monthly intervals to the hub for QA analysis. Many types of image quality inadequacies were detected. These included vertical artifact lines from dirt in the scanning mechanism, inadequate spatial resolution, inadequate contrast resolution, brightness imbalance, and variable distortions of the image. A predictable pattern of digitizer malfunction was not detected. While the quality of some sites remained relatively stable over many months, others deteriorated rapidly. We conclude that a continuous QA image screening program is essential in a hub and spoke teleradiology operation with the type and interval of screening depending upon multiple factors described in this paper.
