RBF Morph will be present at the Conference CompImage 2012 that will be held on the 5th September at the Department of Computer Control and Management Engineering Antonio Ruberti, Sapienza University of Rome, with the paper A new workflow for patient specific image-based hemodynamics: parametric study of the carotid bifurcation by M.E. Biancolini, R. Ponzini, L. Antiga, U. Morbiducci.

Abstract

Engineering applications involving biological fluids have highly transversal requirements in terms of domain definition from clinical images, complex flow conditions, fluid rheological properties, structure motion and deformation, visualization and post-processing of the results.

For these reasons, and thanks to the enormous developments of computational sciences, a computer-aided–engineering workflow seems to be a possible elective environment where to perform hemodynamics studies and medical device design.

Today a large part of the technological requirements needed to tackle these problems in a computational environment are already available in open source and/or commercial software.

Nevertheless, success still strongly depends on technical knowledge and best practice or in other word ideas must be translated into stable and usable implementations.

In this work we present a new workflow based on three fully validated software used to effectively fulfill the requirements related to hemodynamics: the Vascular Modeling Toolkit (VMTK) for the pre-processing step; the mesh morphing tool RBF Morph to impose changes to the vascular anatomy; Ansys Fluent as Navier-Stokes solver and CFD modeler.

As a first test case we focused our attention on the study of a subject-specific carotid bifurcation being this anatomical site of major interest in hemodynamics.
