MR elastography is a new technique using conventional MRI system to assess the elastic properties of tissues. When using pneumatic driver, usually one driver was put at one place of tissue. But the shear wave generated by one pneumatic driver cannot illuminate the large area due to the attenuation. So we use two pneumatic drivers driven synchronously to generate interference shear wave in our experiments...
Magnetic Resonance Elastography (MRE) is a phase-contrast technique using conventional Magnetic Resonance Imaging system to visualize propagating shear waves and study the stiffness of tissues. Usually, shear vibrations are applied to the surface of tissues by means of mechanical driver at one point. But in femoral artery study, the shear wave generated by the single driver on the surface of thigh...
A procedure for the linear finite element analysis of a prismatic beam having random material property is described in this paper. Due to the fact that the material property is described by a random function along the length of the beam and the direct functional form of its variation is unknown, the integration of the strain energy expression may not be possible. This makes the problem very complex...
