초록

The quantitative comparison of brain architecture across different subjects requires a common coordinate system, with respect to which the spatial variability of features form different individuals can be expressed. We have developed and implemented an image warping technique which is based on an elastic body deformation. The resulting 2D deformation map can be used to quantify anatomic differences between subjects. The technique's accuracy is tested, by warping 2D magnetic resonance images of age seventies into Talairach atlas.
