High-Dimensional Deformation Fields for Longitudinal Intraindividual Volumetry of Cerebral Infarction

The aim of this study is the analysis of 3D morphological changes of human brains after cerebral infarction. The change of brain volume caused by the infarction is measured by high-dimensional transformations. These are determined by a multiresolution full multigrid (FMG) movement model [4], resulting in a precise correlation of homologous structures. Thus, volume changes are detected with subvoxel accuracy to determine volume changes between the infarct and remote brain regions without manual interaction. High-dimensional transformations are determined by application of the theory according to Navier-Lamee. Vol…
