Comperative study of FE models of human femur constructed by different approaches
Abstract eng: Methods for fullyautomatic generation of FE model are shortly discussed in the paper. There are two basic principles of reconstruction, voxel based and volumebased methods. The voxel model generation is based on checking all pixel values and defining voxels by means of the selected pixels. Development of the volume model is usually divided into three procedures: tissue segmentation, contour model definition and surface area definition. Three FE models of femur were considered: (i) cortical model (ii) spongiocortical model with homogeneous cancellous tissue (iii) spongiocortical model with heterogeneous cancellous tissue. These models were compared in a simple stress analysis. FE analyses results of all these models are compared with results of experiments conducted using fresh cadaver femur and straingauge measurement.
