Modelling of Human Abdominal Artery for Blood flow Analysis

Abdominal artery (AA) that originates from the heart, starting from the top of the left ventricle is the largest artery in the body and supplies oxygenated blood to all of the abdominal and pelvic organs and the legs. Atherosclerosis which is hardening and narrowing of arteries which result in an inadequate blood supply to vital organs. Anatomical complexity is accomplished using computerized axial tomography (CT) and magnetic resonance (MR) data. The purpose of this work is to create CAD model of abdominal artery. The redundant information such as noises are removed using Thresholding and region growing operation using medical image modelling by a software (MIMICS V19). Further the detail geometric features of AA are examined using software (3MATIC V19) to compare the dimensional details of the anatomical organ. The data is made compatible for computational fluid dynamics (CFD) analysis by converting stereo lithography (STL) data into volume mesh using finite element modeling (FEM) software. Thus the developed Finite element (FE) model can be used for understanding the velocity profile, drug delivery and complex problem associated with the blood flow. (C) 2017 Elsevier Ltd.
