Abstract

The purpose of this study is to incorporate thickness data into a soft tissue model in a laser scanned head data base, for use in FEA modeling of the behavior of the soft tissue layer under mechanical loads. Using a magnetic-based, spatial acquisition system (Polhemus) into which is incorporated an ultrasound sensor the position and orientation of tissue thickness vectors are obtained. By combining this with 3D high resolution head shape data from our laser scanner, a model of the head complete with soft tissue thickness is to be developed. We have implemented an initial version of software for the integration of laser scanning and facial soft tissue thickness measurement. The package displays facial images and performs basic imaging processing. The co-ordinate systems of the two methods are matched with the help of markers fixed on known head landmarks and a 3D digitiser (Polhemus). The computed source locations can be instantly superimposed on the facial images during the analysis.
