In case of using vascular contrast agent, detection of the intima is feasible but detection of adventitia is still difficult. This paper proposes a 3D reconstruction process of blood vessel from CT images with intravascular ultrasound (IVUS) images. The shape of intima is achieved from CT data 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 adventitial shape from IVUS image is appropriately positioned on the curve at the location of the IVUS data acquisition, the cross section shape of adventitia on the location is defined. The 3D surface model of intima and adventitia is constructed from the series of cross section contours.
