Curves-Driven Smooth Deformation Field for Multimodal TVUS-MR Image Registration
نویسندگان
چکیده
We propose a new framework to register and fuse TransVaginal Ultrasound (TVUS) and Magnetic Resonance (MR) Images. The proposed method, first establishes optimal correspondences between pairs of curves by fixing the optimal re-parametrization between each pair of corresponding organ boundaries. Then, the deformation field is interpolated using Cubic Hermite Finite Element (CHFE). As a result, our method does not require predetermined point correspondences and the whole deformation is guided by the organ boundaries displacement. Experimental results on real data images show that our method matches the given curves with high precision and construct smooth deformation fields over the whole image domain.

Mapping and characterizing endometrial implants by registering 2D transvaginal ultrasound to 3D pelvic magnetic resonance images
We propose a new deformable slice-to-volume registration method to register a 2D Transvaginal Ultrasound (TVUS) to a 3D Magnetic Resonance (MR) volume. Our main goal is to find a cross-section of the MR volume such that the endometrial implants and their depth of infiltration can be mapped from TVUS to MR. The proposed TVUS-MR registration method uses contour to surface correspondences through ...
متن کاملGeodesic Active Fields - A Geometric Framework for Image Registration
In this paper we present a novel geometric framework called geodesic active fields for general image registration. In image registration, one looks for the underlying deformation field that best maps one image onto another. This is a classic ill-posed inverse problem, which is usually solved by adding a regularization term. Here, we propose a multiplicative coupling between the registration ter...
متن کاملA Viscous Fluid Model for Multimodal Non-rigid Image Registration Using Mutual Information
We propose a multimodal free-form registration algorithm based on maximization of mutual information. The warped image is modeled as a viscous fluid that deforms under the influence of forces derived from the gradient of the mutual information registration criterion. Parzen windowing is used to estimate the joint intensity probability of the images to be matched. The method is evaluated for non...

Introduction: The purpose of multimodal and co-registration In MR Neuroimaging is to fuse two or more sets images (T1, T2, fMRI, DTI, pMRI, …) for combining the different information into a composite correlated data set in order to visualization, re-alignment and generating transform to functional Matrix. Multimodal registration and motion correction in spinal cord MR Neuroimag...
متن کاملMultimodal image registration by edge attraction and regularization using a B-spline grid
Multi modal image registration enables images from different modalities to be analyzed in the same coordinate system. The class of B-spline-based methods that maximize the Mutual Information between images produce satisfactory result in general, but are often complex and can converge slowly. The popular Demons algorithm, while being fast and easy to implement, produces unrealistic deformation f...
