Abstract
Modern medical image devices provide data which are suitable for computer modeling. Using
the data from a multi-slice 64-CT scanner at German Cancer Research Center in Heidelberg, we
developed a set of software tools for manipulating FE mesh as well as post-processing. In this
work we employed raw data from the CT image device to create a 3D brick mesh of the aorta.
The aorta image was taken from a patient that had an aorta aneurysm so we virtually removed it
and created a corresponding 3D meshed model without the aneurism. Finite element calculation
was performed for both geometrical models, for the aorta with and without aneurysm.
We also created a set of post-processing software tools for representation of the results. It is
shown that the developed software tools are efficient regarding the post-processing time. This
efficiency is very important for future diagnostic and modelling software.
