R. Hren et G. Stroink, APPLICATION OF THE SURFACE HARMONIC EXPANSIONS FOR MODELING THE HUMANTORSO, IEEE transactions on biomedical engineering, 42(5), 1995, pp. 521-524
A method is described to represent the human-torso geometry, as obtain
ed from, e.g., MR imaging, in terms of the surface harmonic expansion.
Three sperific torso geometries, two male and one female, were recons
tructed with the root-mean-square (rms) error < 5 mm using 168 and 248
parameters, respectively. The method can be used in radiation therapy
and enhances the accuracy of forward and inverse modeling in electroc
ardiology.
