FIGURE 4

Regions of interest depicting the (A) aorta and (B) vena cava are drawn manually or automatically using image reconstruction workstations. As these structures are defined, an accompanying surfaced-rendered 3-dimensional image is generated (red-colored aorta with white calcium, blue vena cava). (C) Distracting contrast-enhanced structures such as the kidneys (dashed ovals) can be removed from the 3-dimensional surface rendering. (D) Highly transparent (90%) depiction of the bony structures provides anatomic landmarks for the operator.
