Knowledge of tissue distribution allows the creation of anatomical models of the human body. Anatomically based models are of increasing interest e.g. in the field of medical education, development of therapies and research on the risks of electro smog.The motivation for this work was the creation of a female 3D anatomical model with high accuracy and resolution. The purpose of this anatomical model is to simulate the human physical behavior through the numerical calculation of fields.The objectives were the segmentation of the Visible Female thorax applying digital image processing techniques and the evaluation of existing tools for segmentation and classification. This evaluation should deliver solutions to achieve better accuracy, to reduce the time on manual segmentation and to allow an adaptation of existing tools.
