Example of a 30 mm OCT pullback (bottom) with an identified calcified plaque (vertical line). The plaque is followed cross-section per cross-section and corresponding circumferential plaque measurements are shown. Plaque volume was calculated by the integral of each 2-dimensional plaque measurement over identified plaque length. Horizontal line (A) shows length of stent within the pullback. Stent struts are seen at 3 and 7 o’clock in the cross-section
