Biomechanical Parameters

The main goal of this paper was to determine the biomechanical parameters of abdominal aortic aneurysm using the Bubble Inflated method. In other words, the main task of this paper was to develop a system which would be able to increase the pressure of physiological saline which affects blood vessel tissue and causes its deformation. This deformation is recorded using a camera and providing data at each moment about pressure values which affect tissue and were detected by using a pressure sensor.

Mechanical Properties Characterization

An abdominal aortic aneurysm (AAA) is an abnormal, localized enlargement of the aorta. If untreated, a AAA will continue to enlarge in size and eventually rupture. Currently, AAA diameter is used as the principal indicator of impending rupture. However, this method it is not totally reliable. In an effort to improve the estimation of rupture risk, some researchers are currently studying the mechanical wall stresses of AAAs using patient-specific medical imaging techniques and finite element modeling [1,2]. The accuracy of these models depends significantly on the constitutive law used to describe the mechanical properties of the AAA tissue. To date, only isotropic constitutive laws have been used in these models.
