Figure 2: Visualization of anatomic structures on virtual intravascular endoscopy (VIE) image. A VIE image is generated to look at the ostium of left coronary artery (top left), and corresponding orthogonal views (axial on top right, coronal and sagittal views on the bottom right and left, resp.) confirm the exact location of the structure. The blue box indicates the viewing position placed on the VIE image.
