SOFTWARE TOOLS FOR GENERATING CFD SIMULATION MODELS OF BLOOD FLOW FROM CT IMAGES, AND FOR POSTPROCESSING

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.
