This paper suggests the method to create the individual finite element model by the dimensions only that can be measured easily. Individual head FE models are constructed by transformed a basic head FE head model with matched the individual head outer shape to the basic one by using Free Form Deformation (FED) technique. The individual head outer shape is created by weighted composition of the representative shapes of Japanese head calculated by the method combining Multi Dimensional Scaling (MDS) with FFD technique. Weights for the composition are calculated by minimizing the error between measured head dimensions and calculated ones. Furthermore, the construction method was validated by the comparison of the shape and pressure responses in brain of the head FE model created by the present method with those of the head FE model created from CT images. The suggested method can create individual FE model easily even when individual medical images (e.g. CT or MRI) cannot be taken.
