Human Factors and Human-Computer Considerations in Teleradiology and Telepathology

Abstract

Radiology and pathology are unique among other clinical specialties that incorporate telemedicine technologies into clinical practice, as, for the most part in traditional practice, there are few or no direct patient encounters. The majority of teleradiology and telepathology involves viewing images, which is exactly what occurs without the "tele" component. The images used are generally quite large, require dedicated displays and software for viewing, and present challenges to the clinician who must navigate through the presented data to render a diagnostic decision or interpretation. This digital viewing environment is very different from the more traditional reading environment (i.e., film and microscopy), necessitating a new look at how to optimize reading environments and address human factors issues. This paper will review some of the key components that need to be optimized for effective and efficient practice of teleradiology and telepathology using traditional workstations as well as some of the newer mobile viewing applications.

Figure 1

Example of how a typical radiologist examines a chest image. Circles represent fixations or where the eyes land with foveal vision and the size reflects how much time is spent fixating each location with larger circles indicating more time. Lines are saccades or jumps the eyes make between fixations.
