Geometric modeling of human hand for muscle volume conductor computation

Nerve or muscle action potential fields of realistic anatomy can be simulated using a numerical approach. This paper presents a Sample Surfaces Method (SSM) based on the contour characteristics of the human hand, such as the creases on the fingers, to reconstruct the 3-D contour surface of the human hand for volume conductor computation using the Msc/Patran package. Using the SSM technique the authors define 24 primary sample surfaces necessary to reconstruct the 3-D geometric model of a realistically shaped hand. The secondary sample surfaces between two adjacent primary surfaces could be inserted depending on the desired accuracy of a geometric model. Finally, the authors present several reconstructed, realistically-shaped, human hand models with different boundaries or at different hand positions
