A method system and program product are provided for highlighting high risk structures in a virtual rendering for use during an intervention procedure in a body lumen. A physician performs a CT scan of the body lumen. Using the CT scan a modeling program segments the body lumen and segments a high risk structure. The modeling program determines relative distances between the body lumen and the high risk structure and compares the distances to a marking criteria. The modeling program creates a virtual rendering of the inside of the body lumen corresponding to an interventional camera image and marks areas of a wall of the body lumen corresponding to the comparison of the relative distance to the marking criteria.
