Description

Most measurements on observers' ratings anything in behavioral sciences always involve measurement errors. Similarly, observers' scores on their ratings of medical images contain measurement errors. As it is impossible to remove these errors completely, we are forced to use unreliable data. Therefore, the practical issue is how to assess and utilize the assessed results.<BR>Generalizability study, which has been hardly discussed in the visual evaluation o n medical images, is carried out on two experiments to evaluate medical images.<BR>So far, how to determine the number of interests, subjects and observers has been frustrating investigators, however, the procedure based on the result derived from this study will become useful for the investigators in the future.
