Abstract
When we construct three dimensional blood vessel modeling for numerical blood flow analysis, the extraction of coordinate data of contour on blood vessel region from two dimensional medical image obtained by medical equipments such as MRI, CT, ultrasonic echocardiography through manual image treatment demands many labour and times for researchers. To solve above mentioned problem, we developed an automatic shape extraction method using Snake for contour extraction and pattern recognition by Genetic Algorithm. We can attain to extract automatically the required contour data from medical image for blood vessel modeling on numerical flow analysis. We apply the abdominal aorta and renal artery modeling for numerical analysis of hemodynamics.
