An algorithm for posturing computational phantoms

Abstract

Generation of postured computational phantom is crucial for simulating exposure to electromagnetic field in realistic situations. Most posturing algorithms are based on free form deformations (FFD), which have the defect of incorrectly deform rigid structures of the body (bones) unless specific precautions are taken. We propose an algorithm which guarantees that rigid structures are not deformed. Moreover, parametrization of the algorithm is much simpler than by using FFD.
