Typical Scanning Patterns

Pulmonary Nodule Search
Figure: Typical eye-position pattern generated during pulmonary nodule search.  Small circles represent fixations and lines represent scan paths.

Mammographic Search
Figure: Typical eye-position pattern generated during mammographic search for micro calcification clusters and masses.  Small circles represent fixations and lines represent scan paths.

Skeletal Search
Figure: Typical eye-position pattern generated during search of skeletal images for fractures.  Small circles represent fixations and lines represent scan paths.  The large circle is the locus of a subtle fracture.
