Medical Image Perception & Performance

A Model For Search

  • Global Impression: initial glance at image gives fairly accurate conception of general content of image needed to carry out extensive search.
  • Focal search & scanning : guided by global impression allows reader to scrutinize potential lesion areas with acute foveal vision.
  • Decisions: based on interaction between global impression & focal search.
  • Eye-position recording : helps characterize search strategies & decision making based on this general model.
