  		Fig. 1 —Curved multiplanar reconstruction (MPR) along long axis of vessel (left), and two perpendicular 2D profiles (right) at location indicated on curved MPR (TeraRecon Aquarius workstation). Profile is line crossing lumen, resulting in graph representing attenuation (in Hounsfield units) along that line. Pixels with attenuation values higher than average attenuation of contrast material in opacified lumen minus 3 SD are supposed to be part of coronary lumen.

  		Fig. 2 —Curved multiplanar reconstruction along long axis of vessel shows how software on TeraRecon Aquarius workstation automatically calculates volume inside vessel wall corresponding to attenuation between minimal and maximal values in Hounsfield units.
