Method and device for elastic registration between a two-dimensional digital image and a slice of a three-dimensional volume with overlapping content

Abstract : The invention concerns a method and device for elastic registration of a two-dimensional source digital image of an object of interest with a slice of a three dimensional target volume of the object of interest, comprising defining a Markov Random Field framework comprising at least one undirected pairwise graph superimposed on the two-dimensional image domain comprising at least a set of regular vertices and at least a set of edges, defining at least a grid of control points, each control point corresponding to a vertex of the set of vertices, and a neighborhood system of edges associated with vertices. The method of the invention comprises defining a set of multi-dimensional labels of a discrete space to apply a displacement to each control point, a control point displacement defining a transformation adapted to obtain a plane slice of the target volume and an in-plane deformation transformation of the source digital image. A set of labels is obtained, defining a set of displaced control points, by minimizing an energy target function, the set of displaced control points defining a plane slice of the target volume that elastically matches the two-dimensional source digital image according to the energy target function. The energy target function is a sum comprising first order and/or second order and/or third order terms defined over first, second, third order sets of control points.
