Entropy analysis to psychological evaluation for tomographic images is applied. An optic canal and an internal ear tomogram are taken by hypocycloidal, elliptical, spiral and circular blurring movements. Fifteen tomograms are taken for each tomographic blurring movement of the two different parts, so a total of 60 sheets of tomograms are taken. All optic canal tomograms are evaluated by two groups composed of five ophthalmologists and five radiologic technologists, and internal ear tomograms are evaluated by five otolaryngologists and five radiologic technologists. Each observer participated in this experiment twice, so the total number of tomograms are 120 sheets per ovserver. The subjects were directed to classify 120 tomograms by using a three-category rating scale. Characteristics of each ovserver and each group can be shown quantitatively by caluculated information values.
