    ABSTRACT: The growing appreciation of the pathophysiological and prognostic importance of arterial morphology have led to the realization that angiograms are inherently limited in defining the distribution and extension of coronary wall disease. By IntraVascular UltraSound (IVUS) physicians have a picture of the composition of vessel in detail. However, observing an IVUS pullback it is difficult to figure out the catheter position with regard to the vessel parts and ramifications, and misclassification of lesions is possible. The objective of this work is to develop a computer vision technique to fuse the information from IVUS and angiograms defining the correspondence of every IVUS image with a corresponding point of the vessel in the angiograms. 1.

    ABSTRACT: Intravascular ultrasound images (IVUS) have allowed deepening in the knowledge of the true extension of the coronary vessel illness. Today, vessel diagnosis is limited to observation and measurements in the IVUS planes. For a bigger accuracy, 3D visualization is necessary to allow estimating the extension, localization and severity of the pathology. We develop tools for interactive 3D visualization to extend the views to any sailing angle through the cube of IVUS data. As a result, physicians are allowed to inspect and get 3D measurements about the vessel pathology from IVUS images.
