The uncertainty analysis technique in psychology was apply to a method of radiographic image evaluation with perceptual fluctuation and to a examination of visual evaluation of X-ray grid. A skull phantom was radiographed using four kinds of grids with 30 films each. The total of 120 films were randomly mixed and then assesed by 7 neurosurgeons, 7 radiologic technologists and 7 students in the course of radiologic technology, College of Medical Science, Kumamoto University. The results obtaind were as follows ; 1) The physical characteristics of four kinds of grids agreed with the visual evaluation of skull phantom radiographs by each observer. 2) The fluctuation of visual evaluation by each observer was lower in radiologic technologists than neurosurgeons.
