Abstract

Medical iconography is one of the fields of increasing importance where the physician should particularly welcome the cooperative attention of the biophysicist and his accompanying infusion of sometimes radical scientific methods. The scope of this report is to describe a new approach to medical iconography, which is based on psychophysics and, therefore, it might stirr up emotion and create controversion: but just this is our intention, since we are convinced that the debate of this idea is important enough to be laid before an audience of experts of 3-D imaging systems. Our proposal originates from the recognition that perceiving an information pattern is more than witnessing a signal pattern from which the information pattern is processed. Perception is namely an internal adaptive reaction to the demands made by the world by way of receptor organs, or as internal "updating" of the organizing system to match incoming signals. This can be done in many ways depending on what aspects of information patterns are significant. Our nonconscious a priori knowledge is introduced for grouping the tiles of the signal mosaic, to organize them to perceive what we believe is there. This, however, means that signals of nonadequate stimuli may also be processed in a form which is usually described as "optical image". We are describing techniques which use nonadequate stimuli to get information from 3-D space, and which allow to locate the percepts subjectively in space somewhat similar way as a virtual image of a reconstructed hologram is perceived in space.
