Free-Form Nonrigid Image Registration Using Generalized Elastic Nets

Andriy Myronenko, Xubo Song, Miguel A. Carreira-Perpinan
2007 2007 IEEE Conference on Computer Vision and Pattern Recognition  
We introduce a novel probabilistic approach for nonparametric nonrigid image registration using generalized elastic nets, a model previously used for topographic maps.  ...  The idea of the algorithm is to adapt an elastic net (a constrained Gaussian mixture) in the spatial-intensity space of one image to fit the second image.  ...  Image registration with generalized elastic nets Generalized elastic nets (GEN) The elastic net is a Gaussian mixture with a quadratic prior on its centroids [3, 7, 8] .  ...

Optimal grid point selection for improved nonrigid medical image registration

Clinton Fookes, Anthony Maeder, J. Michael Fitzpatrick, Milan Sonka
2004 Medical Imaging 2004: Image Processing  
Results show that non-rigid registration can by improved by using optimally selected grid points of interest.  ...  This generates two corresponding sets of control points for the two images, yielding a sparse deformation field.  ...  The optimally placed control net is then used to perform block matching between two images to generate a non-rigid registration.  ...

Automated 3-dimensional elastic registration of whole-body PET and CT from separate or combined scanners

Raj Shekhar, Vivek Walimbe, Shanker Raja, Vladimir Zagrodsky, Mangesh Kanvinde, Guiyun Wu, Bohdan Bybel
2005 Journal of Nuclear Medicine  
Although a combined PET/CT scanner removes many of these misalignments, breathing-related nonrigid mismatches still persist.  ...  Registration and fusion of whole-body functional PET and anatomic CT is significant for accurate differentiation of viable tumors from benign masses, radiotherapy planning and monitoring treatment response  ...  Next, using the transformation field, we resample the original PET image (22) to generate a continuous elastically transformed PET image that aligns well with the CT image.  ...
