SSD enable accurate 3-D representations of anatomy, relying on the gray scale to encode surfacereflections from an imaginary source of illumination (Fig. D). SSD images are limited by their dependence on user-selected threshold settings . The 12-bit CT data is reduced to binary data, each pixel either within or outside of the threshold range .Because of this, it can overestimate or underestimate stenosis.
