|Title:||The Viscoelastic Brain|
|Seminar:||The Pritchard Lab Seminar|
|Speaker:||Corina Drapaca, Dept of Engineering Science & Mechanics, Penn State|
|The brain is the most complex organ of our central nervous system; its micro and macroscopic structures are essential in understanding not only the brain’s functions but also its response to mechanical loadings due to surgery, implants, or traumatic injuries. There is increasing experimental evidence that the brain can be modeled as a viscoelastic material, however finding the material parameters of the viscoelastic brain is still an open problem. One modality to find these parameters is the Magnetic Resonance Elastography (MRE), a non-invasive, in vivo imaging technique used to measure the elasticity of a tissue subject to mechanical stress. The resulting strains are measured using MR imaging and the elastic modulus is computed from viscoelastic models of tissue mechanics. In this talk we will present the viscoelastic properties of the brain and the MRE technique.|
