The purpose of this whole study is to find out how radiologists read clinical images by utilizing the eye movement analysis with an eye camera. As a preliminary study, the simple images generated by the personal computer on the CRT monitor were used. A circle with 1cm diameter was selected as a signal to eliminatethe influences of the CRT grade and the observers' eyesight. The signal with various background noise and various locations on the CRT monitor was shown to the observers. In this study, the eye fixation records were analyzed under the conditions such as the fixation angle 2 degrees and fixation duration 100 msec. The physician and radiological technologists working for the gastrointestinal examinations were selected as observers. As the results, every observer easily caught the perceptible signal in peripheral vision first and immediately caught it again in central vision, When the degraded images were shown, fowever, they started searching the signal and the eye fixation records were varied indicidually.
