Color video and photographic displays were compared for their effect on the performance of dermatologists in a test of morphology recognition. The subjects made significantly more errors on images presented in video format than in photo slide format.

We have previously described a user-interactive rule-based computer program (Dyna-SaurI) designed for dynamic thesaurus integration, and demonstrated its efficacy on integrating dermatological subsets of the MeSH and SNOMED thesauruses. In the present study, we have refined our rules for merging and mapping multiple thesauruses and tested these rules. We then applied them with a set of optimized parameters to the integration of a third thesaurus, a subset of the International Coding Index for Dermatology, with the Integrated MeSH-SNOMED thesaurus. The parameter changes resulted in improved ranking of more specific and conceptually closer terms.
A microcomputer-based system for copying, storing, retrieving, and displaying color still images was assembled from commercially available components. The system was tested against 35-mm color photographic transparencies by measuring the performance of 91 medical students in a task of identifying the primary morphology of eight skin lesion images from the displayed images. There was no significant difference in the students' performance between the two display media.
