Brain Cine-MRI Sequences Registration Using B-Spline Free-Form Deformations and MLSDO Dynamic Optimization Algorithm

Abstract

In this paper, a dynamic optimization algorithm is used to assess the deformations of the wall of the third cerebral ventricle in the case of a brain cine-MR imaging. In this method, a nonrigid registration process is applied to a 2D+t cine-MRI sequence of a region of interest. In this paper, we propose to use a B-spline Free-Form deformation model. The registration process consists of optimizing an objective function that can be considered as a dynamic function. Thus, a dynamic optimization algorithm, called MLSDO, is used to accomplish this task. The obtained results are compared to those of several well-known static optimization algorithms. This comparison shows the relevance of using a dynamic optimization algorithm to solve this kind of problems, and the efficiency of MLSDO.
