Application of the surface harmonic expansions for modeling the human torso
Rzzz Hren, G. Stroink · IEEE Transactions on Biomedical Engineering · 1995
A method is described to represent the human-torso geometry, as obtained from, e.g. MR imaging, in terms of the surface harmonic expansion. Three specific torso geometries, two male and one female, were reconstructed 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 electrocardiology.
