Paper Abstract

BAZIS has set up an experimental imaging workstation with facilities for image input, storage, presentation and manipulation. A software package called FRACTALS (Filmless Radiology And Computerized Task Analysis Lab Software) has been developed for an IBM RT PC. An important feature of FRACTALS is a logging facility called computerized task analysis. Every time FRACTALS is started, a journal file is created. This file contains information on e.g. the images that has been displayed, options that has been invoked, window & level settings, time stamps. This information can be used to evaluate the functionality of FRACTALS and to perform research on human behaviour at radiology workstations. In this paper we discuss the porting of FRACTALS from the RT PC to other systems, using the X Window System. Furthermore we discuss the evaluation of the suitability of the RT PC input devices for a radiological workstation using the results of event logging.
