Abstract EN
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.
