Clinical Utility of multiple imaging modalities
larger than QCA but smaller than IVUS (IVUS > OCT = real value > QCA) Coregistration of OCT/IVUS and angiogram might be optimal for sizing of the vessel In plaque characterization, OCT and IVUS(VH) is complementary and the fusion of two modalities might enhance understanding of plaque characteristics (Plaque burden + cap thickness

3D morphologic analysis difficult in IVUS data More art than science Inherently n-D, optimal methods with JEI capabilities (LOGISMOS+JEI) Establishing baseline/follow-up correspondence, deriving vessel geometry 2-view X-ray angiofor vessel shape, data fusion with IVUS

et al.  about the fusion of 3D QCA and IVUS/OCT. They have developed and validated a novel fusion technique based on the 3D QCA from either mono- or biplane angiographic views and the registration with IVUS or OCT pullback sequences. This new and fast approach allows the interventional cardiologist with

3D-QCA* features reconstructions of stenotic coronary arteries and allows quantitative cross-sectional information to be displayed. This off ers automatic contour detection, single-segment analysis, and bifurcation analysis. QCA* features automatic contour detection and analysis of the area of interest.
