Abstract: A technique is provided for the displaying a visual aid tool to facilitate the review of image data which has undergone processing by one or more computer-implemented routines. In particular, the display of the visual aid tool does not obstruct structures of interest in the image which have been identified by the computer-implemented routines. The visual aid tool may allow the magnification of an identified structure, may display relevant information for reviewing the structure, and may allow toggling between result sets for different computer-implemented routines available to process the image data. In addition the visual aid tool may be customized to reflect the preferences or tendencies of individual operators.
