This paper is an investigation on the development of expertise in 3D-CT diagnosis.The protocols data obtained in the experiment were analyzed by using a Japanese morphological analysis system called ChaSen.The results of the protocols analysis revealed differences between the expert radiologists and the novice residents in (1) the number of verbalized words, (2) the variations in perceptual and conceptual vocabularies, and (3) the frequencies of cycles between perceptual and conceptual processing.The results suggest that expertise in medical image diagnosis involves not only the development of both perceptual and conceptual processing, but also the development of an ability to coordinate between perceptual and conceptual processing.
