We propose a new multimodal image registration method when using Magnetic Resonance Imaging (MRI) and Transvaginal Ultrasound (TVUS) imaging separately. Given two sets of corresponding curves in the MRI and TVUS images, we estimate a deformation vector field that registers the TVUS image to the MRI in such a way that the corresponding curves match exactly and the deformation is sufficiently smooth over the whole image domain. Experimental results on real data show that the proposed method outperforms some of the state-of-the-art methods.
