| description | Nonrigid image registration is widely used to estimate
tissue deformations in highly deformable anatomies. Among
the existing methods, nonparametric registration algorithms
such as optical flow, or Demons, usually have the advantage of
being fast and easy to use. Recently, a diffeomorphic version
of the Demons algorithm was proposed. This provides the
advantage of producing invertible displacement fields, which
is a necessary condition for these to be physical. However,
such methods are based on the matching of intensities and
are not suitable for registering images with different contrast
enhancement. In such cases, a registration method based on the
local phase like the Morphons has to be used. In this paper, a
diffeomorphic version of the Morphons registration method is
proposed and compared to conventional Morphons, Demons,
and diffeomorphic Demons. The method is validated in the
context of radiotherapy for lung cancer patients on several
4D respiratory-correlated CT scans of the thorax with and without
variable contrast enhancement. |
