title: [Personal computer-based interpretation experiment system for digital chest images].
abstract: We have developed a system of nodule detection interpretation experiment on personal computers. This system is composed of three subsystems: practice, experiment and check modes. In the practice and experiment modes, chest radiographic images, each with or without a nodule, are shown in a random order on the monitor. The reader is then asked to point a location of nodule and to give a confidence rating. In the check mode, a subsystem shows locations of the real nodules and false positive foci on a figure of a chest radiograph. It also shows receiver operating characteristics of each reader. This system can precisely and easily perform an interpretation experiment. Then reader performance in detection of nodules can be accurately and promptly evaluated. This system, therefore, is very useful to perform a large-scale interpretation experiment in a constant reading condition.
