RADIOLIS - A RADIOLOGICAL INSTRUCTIONAL T RAINING SYSTEM FOR THE SYSTEMATIC EVALUATION OF X-RAYS AS DEMONSTRATED FOR FOCAL BONE-LESIONS

RADIOLIS is an instructional software system for radiological training that guides the user through a systematic analysis of an image. The b ackbone of the analysis is a detailed and structured questionnaire whi ch, as applied to our example, includes all relevant differential-diag nostic criteria for focal bone lesions. The variation range of the rad iomorphologic characteristics in the questionnaire is introduced to th e user with digitized X-ray images, making the simulation of an image analysis possible. In preparation, diverse teaching/learning methods r einforced by instruction psychology were incorporated during the syste m's development. At the core of the training system are an expandable image database and a database containing descriptions of image materia l formulated by radiology experts. The field of focal bone lesions, fo r instance, has already been integrated into RADIOLIS. A graphic user interface and an interactive dialogue enable both comfortable and simp le use of the system and the user-specific structuring of the learning process.
