Abstract

Systems, processors and methods display image views of stacks or volume image data and allow a user to navigate the data and/or views using CAD findings. The systems, methods or processors can generate vicinity CAD marks that have an appearance that varies depending (a) the proximity to the suspected abnormality and/or (b) the navigation direction required to move to the suspected abnormality. The visual appearance of a respective vicinity CAD mark in a view can correspond to proximity of the related suspected abnormality to a current view, whereby the vicinity CAD marks have higher intensity, color saturation, size, or other more dominant visual characteristic in views close to the suspected abnormality and lower intensity, color saturation, smaller size or other less dominant visual characteristic in views further away from the suspected abnormality.
