Abstract

A method for non-rigidly deforming 3D PET datasets is described. The method uses a Lagrangian motion field description and a forward deformation mapping. To regularize the deformation, an anisotropic strain energy function is used that separately models the material properties of cardiac and background tissues. The method is applied to motion compensation in PET so that different time frames of a cardiac sequence may be combined.
