Reference image and corresponding projection CD images. Reference image and corresponding projection CD images of Da (a) and Aba (b) at the level of pulmonary artery and approximately one cm above the bifurcation, respectively. Each column of pixels represent a time point and represents a CD signal from two projections; approximately 400 successive projections are shown. The readout direction is indicated by the red arrow and the time axis is from left to right as indicated by the blue arrow.
