# A fast diffeomorphic image registration algorithm

@article{Ashburner2007AFD, title={A fast diffeomorphic image registration algorithm}, author={John Ashburner}, journal={NeuroImage}, year={2007}, volume={38}, pages={95-113} }

This paper describes DARTEL, which is an algorithm for diffeomorphic image registration. It is implemented for both 2D and 3D image registration and has been formulated to include an option for estimating inverse consistent deformations. Nonlinear registration is considered as a local optimisation problem, which is solved using a Levenberg-Marquardt strategy. The necessary matrix solutions are obtained in reasonable time using a multigrid method. A constant Eulerian velocity framework is used…
