A pointing out and naming paradigm to support radiological teaching and case-oriented learning

Abstract

The simple but powerful idea of annotating images by pointing out and naming is ubiquitous in radiological practice. It is used both by a senior radiologist transferring knowledge to juniors and by any radiologist explaining a case. Pointing out can be realized by pointing devices (finger, pencil, arrows); naming mostly consists of a spoken comment or of a written text. Therefore, radiological examination is multimedia by nature, involving images, annotations, voice, and text. In this paper we discuss an implementation of this paradigm in a UNIX workstation-based multimedia environment for case-oriented learning and teaching. We focus on the authoring and the presentation of radiological study material within this system. Possible scenarios for radiological teaching are discussed. Results from validation experiments conclude the paper.

ABOUT THE AUTHOR Johan Van Cleynenbreugel received a Master Science degree in Mathematics (1981) and in Computer Science (1983) from the Katholieke Universiteit Leuven, Belgium. He has been working in applied artificial intelligence research in the areas of VLSI design, medical imaging and interpretation of remotely sensed image data. He was co-author of the 1985 IEEE CAS Darlington Award winning paper. In 1991 he obtained a Ph.D. from the K.U. Leuven on a thesis covering the use of knowledge-based techniques to integrate geographical knowledge in satellite image interpretation. His current research interests include multimedia techniques for radiological communication and education, visualization and manipulation of 3D biomedical data and 3D image segmentation and modelling techniques.
