Abstract: A system and method for preserving CAD marks falling outside the three-dimensional rendering on a visualization display following segmentation of CT medical image slices for review by a user is disclosed. The CT medical images are processed by both a CAD algorithm and a visualization workstation. The CAD algorithm reports detected suspicious regions to the visualization workstation for display on the three-dimensional rendering of the medical images as well as creates a list of the detections to notify the user. If the detected CAD marks are not located on the three-dimensional rendering of the medical images, the user is notified. The user can the view the detected CAD marks on the two-dimensional CT medical images.
