In achieving 3D model of blood vessel from computed tomography(CT), it is not easy to separate vascular endothelium and vascular wall since the portion of the blood vessel in a CT volume data is relatively too small and has not sufficient resolution nor distinctive voxel intensity. In case of using vascular contrast agent, detection of the vascular endothelium is feasible but detection of vascular wall is still difficult. This paper proposes a 3D reconstruction process of blood vessel from CT data with intravascular ultrasound(IVUS) data. The shape of vascular endothelium is achieved from CT data by segmentation and then converted to polygonal data with iso-surface extraction. A representative shape of the polygonal data is approximated into a B-spline curve. If a vascular wall shape from an IVUS image is appropriately positioned on the curve at the location of the IVUS image acquisition, the cross-section shape of vascular wall on the location is defined. The 3D surface model of vascular endothelium and vascular walls is constructed from the series of cross-section contours.
