Basic Principles of PET/CT Imaging,grid nodes locally irrespective of any coordinate directions, so that curved boundaries can be handled with ease and local regions in which the solution variations are large can be resolved with a selective insertion of new points without unduly affecting the resolution in other parts of the physical domain.

Stretching Method,ching functions which provide the required spacing between the coordinate lines in selected zones. This chapter is concerned with the specification of the stretching mappings and of the intermediate transformations for the generation of grids with node clustering in the areas of solution singularities.

Variational Methods,ates the equations for those coordinate transformations which yield a grid with optimally balanced grid quality measures. The relative contributions of the functionals are determined by the user-prescribed weights.

Unstructured Methods,grid nodes locally irrespective of any coordinate directions, so that curved boundaries can be handled with ease and local regions in which the solution variations are large can be resolved with a selective insertion of new points without unduly affecting the resolution in other parts of the physical domain.

Physiological Variants in PET-CT,neration concerned with adaptation of grids to the numerical solution of partial differential equations has not been covered fully so far in the discussion. The goal of the current chapter is to partly eliminate this drawback by giving an elementary introduction to the subject of adaptive grid generation.

PET and PET/CT in Head and Neck Cancersurfaces. The development of this method was inspired by the need for full automation of big grid codes, which requires an implementation of techniques that enable one to generate in a unified manner both fixed and adaptive grids in domains and on surfaces with a complicated geometry and/or complex physical solution.
